I had the best experience. Thank you.

Dr Cohenca is one of the most kind doctors I ever met in my life. He was so nice, explained me everything about root canal and was very precise with procedure. I recommend this place. Everyone there are so helpful and nice. Thank you!

Outstanding service, outstanding care, professional and personable - I couldn’t ask for a better experience for a root canal!!

Dr. Cohenca and his staff are exceptional. They go out of their way to make the patient comfortable throughout their appointment. Without saying their expertise is second to none. Dr. Cohenca is an expert in his field of dentistry to which I will refer family and friends to him in the event they are in need of his help.

I experienced a sudden toothache and Dr. Cohenca accepted me the same day although their schedule was full! It turned out I needed a root canal care on a tooth that was holding my bridge. He told me there was no need to remove my bridge - he just drilled the hole through it! I needed 2 visits as I had some underlying infection going on, but it all ended very well. He was very attentive to my needs, very gentle and the final result was superb! Highly recommended! Thank you again, Dr. Cohenca! :)

I recently had a root canal at Prime Endodontics and while a root canal is never fun, Dr. Cohenca and his staff made the entire experience as pleasant as it could possibly be. Dr. Cohenca took the time to explain the issue I was experiencing with my tooth and his recommendation for treatment. I was able to have the treatment done the same day. I was provided with noise cancelling head phones I could connect to my phone to listen to music during the procedure. I did not feel any pain throughout the treatment and my mouth was feeling 100x better the following day. Dr. Cohenca and his staff were friendly, professional, and made every effort to ensure I was comfortable throughout. He also personally followed up with me the next day to make sure I wasn’t experiencing any issues. I highly recommend Prime Endodontics!

I would rather get a root canal from Dr. Cohenca then get a simple cleaning anywhere else. Very good experience

I am someone with very bad anxiety when it comes to going to the dentist so when I found out I needed a root canal I wanted to make sure I went to someone who really knew what they were doing. Dr. Nester Cohenca was so thorough and made sure I knew what was going to happen every step of the way. I didn’t feel a thing during my root canal and they gave me noise cancelling headphones so I didn’t have to hear all of the drilling. The procedure went by very quickly and they took X-rays before, during, and after so I felt confident they were being very thorough and I was comfortable the whole time. I highly recommend Prime Endodontics to anyone who needs a root canal.

Glad I went with the team at Prime Endodontics for my root canal.

Glad I went with the team Prime Endodontics for my root canal.

I have had several root canals in my lifetime. They are no fun and I dread having them done. Prime Endodontics gave me the best experience I’ve ever had. They made sure I was as comfortable as I could be and we’re very caring. I highly recommend them.

Great medical office, wonderful and warm experience from start to finish. I Aappreciate doctor who taking time to go over the diagnosis clearly and treatment options. Was referred over by my general doctor and can see why. Highly recommended.

From the beginning the staff is warm and friendly and very helpful. The procedure was explained in detail by Dr Cohenca. Both his assistant and doctor were very calming and answered any questions. I am amazed at how quickly the procedure was complete. Very Professional, very good. Hightly recommend Dr Cohenca and his staff.

I was 15 weeks pregnant with excruciating facial pain that 4 doctors couldn’t diagnose. I saw Dr Cohenca and he was able to fix the pain in 30 minutes by diagnosing it quickly and accurately. He is also supremely kind. Special shout out to his front office and assistant Stephan who both went out of their way to make me feel completely comfortable. I would give this doctor and his staff 10 stars.

Their level of care exceeded my expectations. Pure artistry.

I always hear root canal is one of the hardest procedures ever. With Prime Endodontics it felt like I’m cleaning my teeth not under a procedure. Staff was very friendly offering me and my wife drinks, music and everything that would make you comfortable during the time. Dr. Cohenca is an excellent doctor he never let me feel pain and seems to know what he was doing. Love the place recommended!! Thank you

Very caring and thorough dentist, dental assistants and staff. I highly recommend them for root canals

The Prime Endodontics team was very empathetic, warm, confident, and skilled. I’m a couple days out and feeling fine. It felt fairly easy, and mine wasn’t the easiest case, but I felt completely safe and well cared for. Trusting your team is something you need in more advanced dental care, and that’s just what Prime Endodontics offers. I am thankful for their care!

Dr. Cohenca is a professional, his office staff was really courteous and helpful.

It was a great experience. It was comfortable and smooth. I had no pain after the procedure.

Was a great experience - able to watch the entire procedure via a screen - highly recommend

I will highly recommend Dr. Cohenca and the office for root canal treatment. My first root canal experience was wonderful! Especially touched by these three facts - (1) real-time camera to watch the entire procedure (2) pre-bill confirmation on the responsible amount prior to conduct the treatment (3) send immediate report with all the X-rays to patient electronically. The doctor is calm, patient, and proficiently skilled. All the staffs are warm hearted.

I had for the first time painless root canal work in my tooth with Dr Cohenca. He provided a detailed explanation of the process before getting started. The staff and the assistant are just amazing!

Got me in same day for a quick and painless root canal. The staff was super friendly and Dr. Cohenca was communicative and gentle.

I received a root canal here on a back molar, it was a very pleasant experience throughout and didn't have any issues afterwords. I'd happily recommend Dr Cohenca to others.

Great experience, thank you!

Great experience! Got the same appointment and got scheduled for the root canal procedure the following week. Everyone is very kind and nice, making sure you are ok all the time. Procedure sounded painful but it was completely pain-free. Dr. Cohenca is an excellent doctor! I am happy I was referred to this place. Thank you!

Prime Endodontists was recommended by my dentist for an abses in the mouth. Prime responded to see me on the same day immediately after my dentist visit. Dr. Cohenca diagnosed it to infection of the roots in the tooth near the abses. He immediately drained the abses and releived me the pain and suffering. Within 20 days he worked on the infected tooth and cleared all the infections. Their service is SUPERB and their process is ZERO PAIN. I recommend Prime for all problems related to teeth.

The experience at Prime Endontics was very pleasant compared to any other root canal that I have ever had before. The assistant and Dr. Cohenca explained everything that was going to happen during the procedure, then helped me to totally relax by providing me with headphones playing classical music and a blanket. I could also watch the entire procedure on a televised screen monitor above which helped me to relax even more. Overall it was a very efficient and pleasant experience. Tom O'Neill

The team at prime Ensodentistry was amazing! They took great care of me, especially during a nerve wracking procedure. They even provided a blanket, headphones and chapstick (it’s the little things) to make me more comfortable. I highly recommend Dr. Cohenca and his bedside manner.

Absolutely excellent painless experience, from front began to the end, staff are very professional. Dr. Cohenca did a amazing job. Love it. 5+++ stars!!!

I was referred to Prime Endodontics and Doctor Cohenca due to pain after a crown prep procedure. I called on Friday and was able to get a same day appointment. Everyone was extremely welcoming and made for a very relaxing experience. Dr Cohenca did a thorough exam, and then confirmed I needed a root canal. The procedure was done the same day, in less than 2h. Dr Cohenca and all the staff went above and beyond to ensure I was comfortable and explained everything in detail. For a procedure that gets such a bad reputation, I have to say it was one of the easiest and most comfortable dental appointments I ever had. Will definitely be using them in the future if another issue with pain occurs.

Excellent, professional care. Would never worry about a problem needing their “fixing” again.

I sent a lengthy thank you to the office. This Dr. is beyond excellent!!!!

Dr. Cohenca and his staff provided an exceptional experience for me. They were greatly concerned about my comfort and awareness of the procedure. Before it started they gave me a detailed explanation of what to expect. During the procedure Dr. Cohenca continualy checked on how I was doing and gave me updates on his progress. I experienced no discomfort at all, either during the procedure or afterwards. My procedure was on a Friday, and Dr. Cohenca was so caring that he even gave me his cell phone number so I could contact him over the weekend if I had any questions or problems. The office environment is clean, modern and they use the lasted state-of-the-art equipment. They strictly followed COVID-19 guidelines which also gave a me a great sense of comfort and peace of mind.

My first visit with Prime Endodontics definitely didn't leave me disappointed. The level of skill and professionalism is top notch, the office is lovely (sitting by the fire was very soothing), the staff are wonderful and Dr. Cohenca is definitely top notch. Not sure I would say I'm looking forward to a root canal lol, but if it has to be done, there is no place I'd rather be. 5 stars all around....great location, great office, great team and a great doctor.

Prime Endodontics team and Dr. Cohenca are very caring and professional. I had a swelling in my cheek and I have been referred by my dentist to their office. I want to say I had the most amazing root canal - Yes, there is such a thing!! I am now recovering and grateful to the team 🤩🙏👍

Recently I was diagnosed with needing a root canal, Prime Endodontics came highly recommended. The office is bright and extremely soothing. Dr. Cohenca was fantastic, he explained the entire procedure and answered all my questions. There was no discomfort during or after and I healed in no time. If you are requiring a root canal don't give it a second thought, call Prime Endodontics and let Dr. Cohenca and Frank Sinatra work their magic on you.

Dr. Cohenca is clearly highly trained and experienced professional. He explained to me treatment plan in detail, answered all questions, made sure I was comfortable and completed procedure confidently and painlessly. I experienced no complications and felt good after the procedure. I am happy for being referred to Dr. Cohenca’s office and will recommend him without reservation.

Had an emergency root canal needed with severe pain. They got me in quickly and took care of my needs. Will go back if/when needed for another. Highly recommend!

I would very much recommend Prime Endodontics to my friends and family. Dr. Cohenca is very patient and friendly to his patients. His assistant is very experienced. The impressive part are; they provided iPad to patient during the treatment, have screen for patients to see everything that doctor is doing, after treatment they offer a hot towel to make patient feel comfortable. My right bottom #30 tooth have been bothering me for looong time. I am very thankful for the Root canals treatment in Dr. Cohenca's prime endodontics. Overall l am so glad l did the rootcanal treatment. Its a great relief for me after suffering for long time.

This was my second time I had to do root canal. Nestor is very gentle, explain before what will happen and what I might feel. During all his treatment it was not paintfull and the next day I felt good. Thank you Nestor for making this experience positive for me.

I had a very good experience having an infection identified & cleaned out & then a root canal done to clear everything up above an old cap I had on an upper molar. It was a painful toothache & I feel so lucky to have had it taken care of by Dr Cohenca & his whole team. I will feel very comfortable to have any procedure(s) I may need in the future, due to autoimmune issues, genetics, & some neglect, done here in the future. They were very caring & made me feel very confortable the whole appointment visit. I am a senior & affording dental care hasn’t been easy which is why I say I had some neglect, sadly, with my teeth. I would like to thank Prime Endodontic’s office for their knowledge of individual dental insurance & submitting it. I’d definitely recommend this Dr & office 100 %.

1. Explanation on what the doctor is about to perform was really good 2. RCT procedure was done with great care with detailed explanation 3. I did also like the follow-up which their office done. Usually I haven't seen someone doing it

Dr. Cohenca & his staff responded to my emergency situation by getting me into their office & treating me the same day. Dr. Cohenca is fantastic at his craft & his staff was very professional & pleasant. I would highly recommended them.

I was SO scared to get a root canal. Everyone in this office was just so amazing and helped me through my nervousness. Dr. Cohenca did an amazing job. So caring and professional. I will be recommending to everyone. 5 star service! Definitely don't put off this procedure. You'll be so glad you got it done by him.

I was so apprehensive and nervous before going in to see Dr. Cohenca/Prime Endodontics, in Kirkland. The minute I stepped foot in the office, I was made to feel safe and “heard”. My dreaded root canal was amazing and I never felt uncomfortable in the days after. In fact, after the procedure, I went for a nice walk and was at peace that it was over and was nothing like I had heard, from friends, about their experiences. I’ve been recommending Dr. Cohenca to family and friends (even those out of town). Five ⭐️

Had to have an emergency root canal and they were very accommodating, thorough, and took great care of me, making sure I understood what was happening during each step of the process

He is the best in the world 🌎

When you are dealing with infection it pays to find someone you can trust to deliver excellent care, & in my experience you are in exceptional hands with Dr. Cohenca. His credentials are impressive: 29 years of clinical, research & teaching experience, expertise in dental traumatology (when bad things happen) & pediatrics (when bad things happen to kids), and a multinational and multi-lingual background — which point strongly to an abundance of knowledge, experience & developed technical (& communication) skills. But what brought me to his current practice was prior experience: 13 years ago I was treated by Dr. Cohenca at the UW following a bike and sailing accident. Back then I expected root canals to be ‘character-building:’ yet in his hands the procedure was quick, easy and the aftermath so ‘unremarkable’ (no complications then or now) that I forgot about it. So when I needed another root canal, I sought his care. This time my procedure was finished in just over an hour, I was sent home with standard aftercare instructions but less than 6 hours later woke from a nap experiencing no discomfort or pain whatsoever (note: mileage may vary, situations are unique/multi-factorial, pain subjective etc). Weeks later, I continue in the path of ‘unremarkable’ healing. The clinic displays professionalism (there’s in-built follow up in care, communication is easy & Dr. Cohenca makes himself readily available) but what stands out is a sense that Prime Endodontics is a practice founded on transparency, integrity & basic good practices founded on patient health. Having ‘trust’ issues and desire to understand I ask a lot of questions yet Dr. Cohenca and his staff took time to answer all my questions, clearly lay out what I should expect as treatment & aftermath, and I personally appreciated Dr. Cohenca’s tendency towards frankness and honest, pragmatic opinions (should you ask for them). There’s a deliberate transparency from billing (write up with a clear breakdown of what’s to be charged insurance etc) to procedure (should you choose to you can watch it take place in real time, which may in turns fascinate/ educate/ distract etc) to post-procedure assessment & management of expectations. Dr. Cohenca also shows & explains the results of his work: in my case, a lateral canal at right angles making my root system look a bit like a game of Tron, and a ‘core build-up’ smoothly built to prevent infection or trauma. Inappropriately performed procedures can lead to problems/re-treatments down the line and our current system can cause strange pressures and incentives that lead to clinical decisions not always in the patient’s best interest, so having trust in a clinician’s skill, devotion to excellence and professional integrity is key. As an established researcher & clinician & teacher Dr Cohenca seems committed to providing evidence-based care tailored to a client’s situation, to lay out treatment & expectations in a clear, open manner, and to educate and empower his patients with information. All these things build trust, and hence I would feel confident in returning should complications arise, or future treatments be needed. & that feeling of of confidence in getting good care - is priceless. p.s. also from experience: if you're usually 'asymptomatic' or have 'mild/moderate' symptoms and they start to subside/go away, don't put off an evaluation. Denial may be a long river but it will get you nowhere & not all 'pulpitis' reverses itself (trust me). Be healthy,

Amazing! I was referred for molar re-treatment and knew I was in good hands as soon as I walked in the door. The staff are relatable and very professional. Dr. Cohenca is very knowledgeable and accessible. My pain was relieved the same day of treatment. Thank you! If I ever require a root canal I will not have the general dentist address but rather come here because I know my issues will be addressed quickly and professionally.

Dr Cohenca is a wonderful Doctor and took excellent care of me. He doesn’t do a root canal unless it is absolutely necessary and I really appreciated his honesty and care.

My time at Prime Endodontics was THE most pleasant experience I've had when it comes to endodontics. First off, not only is Dr Cohenca extremely knowledgeable and thorough in his treatment explanation, but his calm and gentle demeanor puts you at ease. In preparation for my retreatment, I had revealed I become extremely nervous and am sensitive to the slightest bit of pain in which they prescribed a type of sedative and made me right at home with a blanket and noise canceling headphones. I felt absolutely NO pain and the experience was better than I could have imagined. I highly recommend Prime for any and all of your more complex dental procedures.

Dr. Cohenca treated my daughter with a root canal. Besides being a fantastic professional he was very patient and attentive to her fear. Explained the course of the procedure and got her full cooperation. Problem was solved with no complications and no after pain. Thank you very much Doctor and wonderful staff

Very caring and helpful staff. Dr. Cohenca was excellent! He explained everything along the way and made the RC as comfortable as possible.

For having a root canal it was the easiest and painless experience. I actually fell asleep during the procedure. They staff was so good the doctor did a fantastic job

I took my 8 year old to see Dr. Cohenca after a bike crash and damaged tooth that needed a root canal He was WONDERFUL with my child - and I was especially impressed with how careful he was to win trust and gain my child's consent. He insisted that the procedure would only happen if the patient was consenting and comfortable, was careful to communicate each step as it happened in terms that could be understood by mother and child, and overall it was a very positive experience for us, in the midst of a pretty rough week.

Dr. Nestor received me at short notice in light of my urgent request, quickly diagnosed the problem and treated me that day. The treatment was professional and courteous. Doctor Nestor is so gentle and kind. He's just an angel!

I highly recommend this orthodontist! I was referred after finding out I needed a root canal and the experience I had was exceptional. From the way I was greeted to the procedure it was a really comfortable and great experience. The staff was very professional and empathetic for their patients. I will be coming back and recommending anyone who needs it. Thank you all so much!

We received excellent care for my 13 year old daughter when she had to have root canals on her front 2 teeth. Later she did not believe me when I told her that she had shots to numb the area. This was because Dr.Cohenca and his assistant did not rush through the procedures and they were very concerned with her comfort at all times. They were also very diligent to answer any questions my daughter and I had. The kindness, professionalism, and later follow-up from both Dr. Cohenca and his staff was very much appreciated. I highly recommend this office.

Awesome experience. Dr. Cohenca and staff were caring and took extra care to ensure that I was not in pain and that my procedure was as stress free as possible.

Very patient with me since I was so nervous. Explained the procedure very well and did their best to keep me calm. Very professional. No more pain after my root canal 3 days ago. What a relief.

Dr. Cohenca and his staff were wonderful with my son during his dental emergency. They told us what was happening in each step of the procedure and made sure he was comfortable with noise-cancelling headphones, music and a blanket. The care they provided made the experience a smooth one. I would highly recommend this office!

I saw my regular dentist for extreme pain, she referred me to Kirkland Prime Endodontics for an immediate appointment. Her office called them and they got me in within the hour. That in itself was impressive since I drive to Kirkland from Milton. I went to their office after filling out all information online in my car, my dentist had given them all my insurance info so that was a plus!! When I went in I was greeted very warmly, they took my temp due to covid, ask me a few questions, next thing I know I am being taken back to a nice room, where Stephan prepped me for my exam by Dr Nestor Cohenca. He came in, did a few things said yes I needed a root canal, explained to me the procedure he would do to save my crown, they went right to work, got it done, and everything went great!!! It was completed in about an hour for everything!! I must say that was the most pleasant experience I have ever had having a root canal done! If ever I need another, or if I know someone who needs I will definitely recommend them to Dr Cohenca. The care of the Dr., and the staff was truly wonderful. Thank you Dr Nestor Cohenca and all the staff for the compassion and professionalism I was shown... Blessings to you all!!!!

I was immediately greeted with a friendly receptionist and was taken right away to see Dr. Cohenca. I must admit, after two previous root canals, it was the best root canal experience I have ever had. Dr. Cohenca was very gentle and kind, explained the entire process and I didn’t feel an iota of pain while he was working on my tooth. My tooth (under an existing Crown from 4 years ago) was very inflamed and I felt exposed the nerve with any cold/hot food/water. Generally after a root canal you start to have pain after the numbness goes away. It has been two days since he drilled thru my existing gold crown and completed the root canal procedure. I would be less concerned and much more motivated to go back again should there be a need for another root canal. Thank you very, very much Dr. Cohenca and your wonderful and very friendly assistant, Forgive me if I did not remember her name. I will highly recommend Dr. Cohenca. You would be crazy to go with anyone else. This Doctor is extremely caring, kind & second to none.

I waited and waited for the pain to come and after one week I’m still waiting:-) I will certainly ho back again should there be a need for another root canal. Thank you yo you Dr. Cohenca and your wonderful and very friendly assistant, I believe her name was Dana. Forgive me if I did not remember your name. I will highly recommend Dr. Cohenca.

Dr. Cohenca and his staff did an incredible job on my root canal. They were kind and welcoming, explained the procedure clearly and even showed me before and after xrays to illustrate the work that was done. Dr. Cohenca personally called me the next day to see how I was doing. It was a down to earth experience that seemed like how all medical/dental procedures should be. I’d highly recommend prime endodontics to anyone who is looking for a root canal, being my first one I was quite relieved it wasn’t nearly as bad as they’re made out to be!

The team, lead by Dr. Cohenca, clearly explained what they were going to do. They put me at ease before we got started, and during the procedure they explained their progress. I never experienced pain outside of the brief moments of the initial painkiller injections. When all concluded Dr. Cohenca gave me clear explanations of what I should and shouldn’t do. He also gave me his mobile number in the unlikely event I experienced any post-procedure complications. Fortunately, I had no complications. While I hope to never have another “endodontic procedure”, if I do I will come straight to Dr. Cohenca and his terrific team.

My Dentist referred me to Prime. I went in and was evaluated and came back two hours later and received a complete (and painless) root canal and was home with my toothache completely resolved. I was very happy.

.

Recently had root canal therapy.  Dr Cohenca and his staff were exceptional! So very friendly and really showed concern for my care .  Highly recommended!

I just got back from my double root canal with Dr. Cohenca. I was apprehensive, since I hadn't had a root canal in ... 20? years....and these were on my two front teeth. I couldn't have been more pleased w/ the experience! From the person at the front desk, to Stephan and Dr. C--wonderful1 No pain Jazz to listen to! It could not have been easier. I am forever grateful!

Dr. Cohenca was very thorough in his work. I had no pain during or after my root canal. He explains every treatment option specifically designed to you in no rush. He makes his patients feel as though his time is dedicated to their appointment alone, and he is soft spoken, kind and will go the extra mile for patient care!

I needed a root canal precedure done, and would like to say it was a very smooth operation by Doctor Cohenca.The Doctor and his staff at Prime were professional, personable and informative. I was able to see the before and after his surgery.I had very little discomfort during my healing.I would recommend him to anyone.

I had to have my first root canal taken care of and I found Dr Cohenca after doing some research online. When it comes to dental work I’ve learned the hard way that you must find the perfect fit to make the experience less traumatic and painless. First impressions are everything like they said; I gave a call to the office and from the beginning I experienced great professionalism and care from Julie, she listened to all my questions and concerns and is for sure a great asset to his team.The day of my appointment I arrived into a clean, modern office with a great location. Dr Cohenca explained what the appointment will consist of and his Dental Assistant Stephan and him took care of the procedure promptly and efficiently. They offered some after care instructions and recommendations. I can’t praise Prime Endodontontics enough, I had an excellent experience and I couldn’t be happier!

Needed a last second root canal and Prime Endodontics was amazing.  Dr. Cohenca and his staff are extremely professional and personable; I have never felt so at ease in a dentist office.  I hope I don't need another root canal any time soon, but if I do, I know where I'm going.  Thanks!

I was referred to Dr. Cohenca by my dentist for re treatment of root canal. From customer experience point of view I was treated very well and I felt comfortable. Every detailed was explained to me and I knew exactly how much I will be charged and what kind of work will be done. From technical point of view, my dentist says by looking at the post work xrays, he did excellent job. Thank you Dr. Cohenca team!

I was referred to Dr. Cohenca  through my dentist , unfortunately for a root canal. I have never in my life had this procedure done so I was a little apprehensive and nervous. From the time I entered their beautiful office To the time I left it was an a great experience .The  staff were warm and friendly , they explained everything thoroughly, l was given a headset to listen to music to helps me relax and Dr.Conhenca Explained everything thoroughly. It was completely pain-free and after having a toothache for three months it was completely gone the next day. I would highly recommend this office 😍

When no one else would see our son due to the closure Dr. Cohneca helped us and made time to not only see but treat him! We are SO THANKFUL for the kindness of Dr. Choneca and staff!!!

The entire staff is very professional and show true concern about you as patient! Dental procedures are not fun, but they make you feel at ease and as comfortable as possible. Highly recommend them!

Good service, able to get help with very short notice and everything was as it should be. I’m a happy customer.

I recently went to Dr. Cohenca for a root canal. Initially, I was quite nervous. But Dr Cohenca is a very good doctor. He spent time throughly explaining the procedure. The office was decorated in calming colors and Dr. Cohenca provided earphones so I was able to listen to Claude Debussy the whole time, which helped considerably. All the assistants were kind and professional and frequently asked me if everything was all right. The procedure went very well and I was so happy to not have the painful toothache.

Dr. Cohenca was recommended for our daughter's root canal, and he did not disappoint! Everyone in the office was fantastic but most importantly the work done was excellent and the whole experience deserves a 5 star rating.

I had a dental emergency in the midst of “stay at home” and they made a safe and timely space for me.  One root-canal later and all is well.  I was treated well and the procedure was easy and painless.  Highly recommend!

I called Dr. Cohenca's office today after enduring a weekend of excruciating pain. They were able to get me in this afternoon, which was such a relief. After locating the offending tooth, Dr. Cohenca thoroughly explained his treatment plan to me. After numbing me up, it was root canal time. It sounds strange to say, but this was the most relaxing dental procedure I've ever had (and I've had plenty). I'm used to lying in a chair, staring at bright overhead lights, and listening to cheesy soft rock music while the dentist drills away. That wasn't the case here at all. They dimmed the lights, gave me a blanket, and provided me with Spotify and noise canceling headphones. I nearly fell asleep during the procedure, which speaks volumes about how gentle Dr. Cohenca and his assistant Stephan were. As I write this, I am finally pain free for the first time in a month. Dr. Cohenca is a master of his craft and I highly recommend him. Well done!

Dr. Cohenca and staff will give you such a good root canal at their sparkling new Market St. location that you'll want to come right away for another!Seriously, what can you say about the unpleasant experience of a root canal except that the doctor and staff made it as humanly pleasant as possible? Dr. Cohenca is super professional and has been doing this for many years. Dr. Cohenca has a soft, calm demeanor that puts you at ease. He talks to you before the procedure and fully answers questions. A few days after the procedure, he called me personally to ask about my condition and answered a few more questions. Many doctors, if they do call back, have a staff member call.I felt like Dr. Cohenca and all of his staff took care of me well and did the job with ultimate professionalism. His office, facing Market St. in Kirkland, has large picture windows with plenty of natural light that help make the patient feel even more comfortable.

Dr. Cohenca did an emergency root canal for me as a referral from my dentist.  The procedure went very well and I was very impressed with the doctor and the entire staff.

Dr. Cohenca was wonderful as was the rest of the staff. For someone who doesn’t like the dentist and extreme anxiety, this was probably one of the best experiences I’ve had. Dr. Cohenca walked me through each step to help calm my nerves. Very thankful they were able to get me in quickly!

 I had a very pleasant experience with Dr. Cohenca and his staff. Mr. Cohenca is very professional, he takes the time to explain what needs to be done and provides valuable advice.I came in for an emergency root canal during a very stressful time for many, but they made sure I felt at ease and comfortable. They scheduled me in for the exam and procedure on the same day, which was very nice. The staff is amazing, sweet and very knowledgeable. The office is beautiful and very well taken care of. Meeting Nestor Cohenca was a pleasure, not only is he thorough and informative, but he is also very sweet and knowledgeable in his field. I would go back a million times but let's keep it to one time only.

Great

Can I just say, as a colleague and fellow dentist, Dr. Cohenca is exceptional! I refer difficult cases to him and he sends me detailed reports, with X-rays and photographs, unlike most of the specialists I work with. He goes above and beyond to deliver quality care (even during quarantine) with integrity, honesty and clinical excellence. Furthermore, Dr. Cohenca was my instructor at the University of Washington School of Dentistry over 10 years ago and I always remember him for being kind, enthusiastic, and fair.  He was world-class educator for many years before opening his private practice. I would refer friends and family to Dr. Nestor. Thank you for making an impact!

I just wanted to thank the team that assisted me yesterday. Every effort was made to make me comfortable and the procedure pain-free. I greatly appreciate that I was able to be seen and treated so compassionately during these exceptional times.

I sent my dentist an email on a Sunday night about major tooth pain that I was experiencing. The next morning, I was contacted by Karen at Prime Endodontics with an appointment the FOLLOWING DAY! Bridget set me up, Dr. Cohenca performed a root canal flawlessly and without pain, and I even got a complimentary lip balm! They are truly amazing. I highly recommend their services. Great people...

Amazing Staff and Service.  The staff made me feel comfortable every step of the way.  My procedure was explained well and the staff was more than accommodating. Best dental work I have had.

I was more than satisfied with my appointment. Everyone was professional and went the extra mile to make sure I was comfortable throughout my procedure. The service was exceptional and I left feeling very happy with the results.

My daughter had her regular teeth cleaning at our old dentist and they didn't notice she had a cavity. Later we went to a new dentist and was told my daughter's cavity was so deep that she might have to do a root canal. We were referred to Doctor Nestor Cohenca, who's the best doctor we've ever seen. He talked to my daughter about how this is going to be done and what she would experience in a very friendly, calm and professional manner. I watched the whole procedure and I believe he's the best in this field. Not only did he save the tooth, but he didn't have to do a root canal, just a Therapeutic Pulpotomy. I'd highly recommend him if you ever need an Endodontist.

I was in pain and was having a hard time finding someone that I felt comfortable with that was able to treat my issue. Dr. Cohenca and his staff made me feel comfortable and confident in him to address my issue. He did a retreatment of one of my former root canals because it showed that it needed treatment in the Ex-ray that his staff took and I am feeling a lot better now.

My dentist accidentally drilled too close to a nerve when he was prepping my tooth for a bridge, which caused me to have excruciating pain. They were kind enough to set up an appointment on my behalf with Prime Endodontics. I could not wait for the scheduled appointment and reached out to Prime to see if they could see me earlier than what was scheduled. Their staff was kind, professional and thoughtful. They had lip balm and even offered me a blanket to ensure that that I was comfortable. Dr. Cohenca stayed to sort out my tooth, even though it was his birthday. They even called the following day to check up on me. Great service, professional and caring staff. I highly recommend Prime Endodontics!

Very happy with my experience. Warm and relatable staff. Efficient and well-organized, professional operation, too. Dr. Cohenca took the time to make sure he answered my questions and provided full details. I felt very well cared for. And both he and the staff followed up with me after the day of treatment to make sure my recovery was going well. I'm not eager for another root canal, of course, but if I need endodontic care I will come back here again, no question.

I had a great experience with Dr. Cohenca. He knew I needed a root canal, he explained the whole procedure and made me feel very comfortable and the procedure went on very smooth. I would like to thank Dr. Cohenca and his team!

I got 4 root canals in a 2 week span done here, and I couldn't recommend them more. They got me in quickly for appointments, the staff are nice, respectful, and friendly. The facility is very clean and modern. Dr. Cohenca is very good at what he does, doing the work with minimal pain and utmost comfort. He works quickly and efficiently and is very caring through the whole process. I have quite a bit of dental anxiety and the whole office worked to make me feel as comfortable as possible.

 Saw my dentist and she recommended that I see Dr. Cohenca for a possible root canal.  My dentist called and they could see me that same afternoon.  Dr. Cohenca even scheduled me that next day for the procedure.  I didn't have time to even think about what was going to happened.  I had always heard horror stories about root canals and I don't know about those other people but my experience was nothing like that!!  Dr. Cohenca was wonderful, him and his assistant had great bedside manner always making sure I was OK!  I highly recommend Dr. Cohenca for your dental needs!!!

Had Root Canal and Root Canal Retreatment done across two days. Dr. Cohenca is really experienced, and far better than any previous endodontist I’ve ever dealt with. He is thorough in his work, which can be seen in the x-rays. He makes sure you are getting your money’s worth. You can tell he is an honest guy who’s giving you the correct treatment advice, even if it means leaving a tooth alone for the time being. He makes sure you’re comfortable during your treatment by giving you a blanket, dimming the lights and giving you noise canceling headphones with a tablet so you can listen to your favorite music while he and his assistant go to work. Not lying, but today during my root canal, I actually had to make a solid effort not to fall asleep - I was THAT comfortable and relaxed! Highly recommended endodontist! Oh, he also has the very latest tech in his office. Not those dated Windows 7 computers that keep hanging up!

Prime Endoontics is highly recommended! Dr. Cohenca and staff are very professional and very knowledgeable of their craft. Office is beautiful and all staff makes you feel like your home. My procedure was an emergency case and Dr. Cohenca and staff stepped in and made the procedure painless and quick! Definitely will go back if I need work done. Thank you!

I had to get 4 root canals done nearly back to back, this office took every step to make me feel comfortable and ease my dental anxiety for these procedures. Dr. Cohenca and his assistants have very good bedside manner and I would recommend them to anyone. The work was done effectively, quickly, and comfortably.

As one who suffers from anxiety prior to dental treatment, Dr. Cohenca has done a phenomenal job at attending my emotional state while performing the necessary oral treatment. He is quick at responding to emergency situations and putting the patient’s need at the highest priority. The staff at the clinic are warm and welcoming.

As someone who has anxiety before dental treatments, Dr. Cohenca has been extremely attentive to my needs while providing the highest medical care one can expect. He has proven time and again to always respond in emergency situations and place the patient’s priority on top. The staff and office are warm and welcoming, always making sure that you feel safe and well taken care of.

After my dentist found a problem under one of my teeth, Dr Cohenca was able to solve the issue. Very friendly and professional staff.

They were great. My dentist sent me to them and he is picky so right for the bat they had to be good. And yes they are. Took me right in everyone was very nice and helpful. Dr Cohenca checked me out and when to it. Not only that he is a nice guy. Not in pain anymore.  My dentist was right Dr. Cohenca is good any more problems with my teeth I would go back.

I can't imagine anyone needing to come here is in a good mood because something is very wrong to have to see an endodontist. With that said, the experience from the first phone call with the receptionist to the dental assistant to Dr. Cohenca is just top notch!! They office is sterile clean (Im the type to look at the dust build up on base boards at the dentist) yet so warm and inviting with their decors! Best of all, everyone was so friendly in a genuine way. Dr. Cohenca himself is so thorough in his exam and explanations. He really took the time to answer all my questions and come up with a plan for my case, even if it meant to further refer me to another specialist. If it helps your decision, I was referred to this office because my friend who is also an endodontist herself told me to come here after seeing his x-ray work on her friends. She said they did an impressive job on a difficult case.

I highly recommend the Prime Endodontics! Dr. Nestor Cohenca is very professional! He have the highest technology for x rays. It was really a great experience for me today.

I wrote a much longer review and unfortunately it did not get published so this one will be shorter. Overall, this is the best medial experience my wife and I have ever experienced. Dr Cohenca fit us into his busy schedule, walked us through the results of both CT Scan and XRay so that we could be knowledgeable... we had to go to ER ultimately two days later and Dr Cohenca and his entire staff checked on us the entire time. Best service and care ever

The experience was top notch from beginning to end. They were able to see me immediately after my dentist referred me for an emergency root canal. The doctor and staff were all extremely attentive and caring. They understood my dental anxiety and went above and beyond to make sure I was comfortable at all times.

I'm very happy with my experience with Dr. Cohenca, who diagnosed an issue with a sensitive tooth and was able to perform a root canal immediately.The facilities are top-notch, everybody was very attentive and kind, and I actually had a great experience. Highly recommended!

Dr. Cohenca and his staff were fantastic! They took their time to explain about my situation, process, and options.   They made sure I was comfortable throughout the procedure  and even called me the next  day to check how I was feeling. Thank you!!!

I needed to have an emergency root canal and Dr. Cohenca and I had several telephone calls on Easter Sunday to diagnose my symptoms and schedule an appointment for the following morning.  Dr. Cophenca thoroughly explained the procedure and performed it with little to no discomfort.  I could not have been more impressed and thankful for Dr. Cohenca.

I sent my dentist an email on a Sunday night about major tooth pain that I was experiencing. The next morning, I was contacted by Karen at Prime Endodontics with an appointment the FOLLOWING DAY! Bridget set me up, Dr. Cohenca performed a root canal flawlessly and without pain, and I even got a complimentary lip balm! They are truly amazing. I highly recommend their services. Great people...

Pleasant staff, very friendly and helpful.  I changed my previous clinic and was shocked by what could be so good when treating my teeth.  In my opinion, a dental clinic should be just like this.

 Had I known root canals could so painless and comfortable I wouldn't have suffered for over a year with a cracked tooth. Dr. Cohenca and his staff really took the time to ensure I was comfortable and understood the procedure. The entire process took only about an hour and a half and Dr. Cohenca and his staff really went above and beyond to make sure I was comfortable the entire time, from giving me a blanket to remembering special health issues before I could even bring them up. I just adore this man and his staff for taking such good care of me when I was terrified and the best part is now I am pain free!

Let's be honest....no one wants a root canal.  I, like many others, was not looking forward to the procedure.But from the moment I walked in the door I was treated with amazing care and the overall experience was unbelievable.The staff was kind, the Dr helped me understand the procedure, and answered all of my questions, and ultimately I never felt intimidated or uncomfortable.During the procedure itself, I was relaxed, felt no pain and at ease at every moment.Although I won't say I'm anxious to go back again, but if I have to, I have no fears or anxiety.Thanks for making my visit easy and comfortable.You run a class act operation.

Very professional. Pain free appointment. He made sure that I was comfortable thruought the procedure.

Dr. Cohenca is a superior endodontist and one of the most compassionate individuals you will ever meet. His root canals are pain free, and he and his staff treat patients with the utmost respect. While there are multiple endodontists in my immediate vicinity, I will willingly drive 30+ miles to Everett to be his patient. I'd rate him 10 stars if I could.

Dr. Cohenca and the entire staff at Lakeside Endodontics are outstanding! Dr. Cohenca is an expert at what he does and treats his patients with respect, consideration and professionalism. He runs a superior practice -- where patient comfort, satisfaction and excellence take precedence. .A++

Excellent and pain free
