Are Root Canal Retreatments Common?

The root canal system is very complex—and while some root canal treatments don’t result in any future issues for the patient, others can become re-infected months or even years after the initial treatment.* If you’re experiencing pain or swelling in a previously treated tooth,** you might be dealing with a failed root canal.

When Are Root Canal Retreatments Needed?

There are a variety of reasons root canal retreatment becomes necessary. One of the main factors is related to the complex anatomy of the root canal system. If the narrow, curved canals within the root canal system are not thoroughly cleaned and disinfected during the initial treatment—or they go undetected altogether—the tooth may become infected again.*

root canal retreatmentDuring standard root canal treatment (RCT), files and treatment fluids are used to remove the infected tissue and clean and disinfect the canals.*** But since the root canal system can consist of narrow and curved canals, it can be difficult for the files used during standard RCT to reach all the infected tissue.*

Fortunately, the GentleWave® Procedure offers an alternative to standard root canal treatment that can help reduce the chances of a failed root canal.4
