What is Endodontic retreatment?

Endodontic retreatment is a root canal procedure that is performed on a tooth that has had root canal therapy (RCT) in the past. It's also sometimes referred to as a “root canal retreatment”, “root canal revision”, or, “endodontic revision”.

Why is retreatment needed for some teeth after a root canal?

In the vast majority of cases, root canal therapy is completely successful. But sometimes, a retreatment may be necessary, usually, when one of the following issues arises:

  • Narrow canals that were missed or not treated initially have been infected and required treatment
  • The sealer used in the restoration did not adequately prevent contamination
  • Crown placement following the procedure was delayed, enabling the tooth to become damaged or infected
  • The crown has become damaged, resulting in infection or damage to the tooth it protects
  • The tooth has become broken
  • Other areas of the tooth become damaged or infected, exposing the treated area to infection as well

How can I tell if I need retreatment?

Most people who need retreatment will continue to experience pain and discomfort in and around a treated tooth, as well as increased sensitivity to hot and cold foods and beverages. An office exam and dental x-ray can help determine if another root canal treatment is needed or if another problem is occurring.

What happens during endodontic retreatment?

During the procedure, the crown will be taken off your tooth, and the filling material that was placed in your tooth during the first procedure will be carefully removed. The canal area will be carefully examined and evaluated for infection in the main canal or tiny narrow canals, removing damaged areas as they're identified. Then, new materials will be placed in the cavity, and the area will be sealed. Once healing occurs, a new crown will be placed over the tooth.
