With proper care, even teeth that have had root canal treatment can last a lifetime. But sometimes, a tooth that has been treated doesn’t heal properly and can become painful or diseased months or even years after treatment. If your tooth failed to heal or develops new problems, you have a second chance. An additional procedure may be able to support healing and save your tooth. If you are experiencing dental pain or discomfort in a previously treated tooth, talk to an endodontist about retreatment.
As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:
In other cases, a new problem can jeopardize a tooth that was successfully treated. For example:
During retreatment, the endodontist will reopen your tooth and remove the filling materials that were placed in the root canals during the first procedure. The endodontist then carefully examines the tooth, looking for additional canals or new infection. The endodontist then removes any infection, cleans and shapes the canals, and places new filling materials. The opening is then sealed with a temporary filling. Once the tooth heals, a new crown or other restoration is placed on the tooth to protect it.
