Even though a root canal lasts over a lifetime, sometimes, the tooth might need to be retreated as a result of infection or an incomplete first procedure, a situation may arise when the patient may require a root canal retreatment on the same tooth.
When do you need a root canal retreatment?
You might need to undergo a root canal retreatment if you have:
A fractured tooth
A cracked, loose, or broken crown or filling
New infection or decay
A narrow canal that went untreated the last time
A problem that wasn’t detected in the previous procedure
When saliva gets into the tooth and re-contaminates the root canal
A root canal treated poorly
How will you know if something is wrong with your root canal?
If the previous root canal goes wrong, then you will feel severe pain or discomfort. Some even report extreme pain while exposing the tooth to hot or cold temperatures. You will find the portion around the tooth swollen or bleeding. In some cases, the tooth gets loose, making the gums pull away. That is why it is necessary to go for regular X-rays, dental cleanings, and also maintain good oral hygiene. In some rare cases, you may not feel pain, but still have an infection, and that could be detected in a routine dental exam.
What happens during the root canal retreatment procedure?
At first, the endodontist uses a 3D Imaging technology and Surgical Operating Microscope to determine the cause of root canal failure. After determining the problem, the endodontist numbs the area that is to be treated. He creates a small access opening into the tooth. He removes fillings or other materials that are placed in it to protect the root canal. He also removes any infection found in the canal.
As the affected portion is unobstructed, the endodontist reshapes and disinfects the canals. He uses various medications and irrigants for the process. The dentist then fills the area with a temporary filling. After the healing process, the endodontist places a crown as a final step, for the protection of your tooth.
