A second root canal, also called root canal retreatment, may be needed when a previously treated tooth does not heal as expected or develops a new infection.
Possible reasons include:
- A previously untreated canal
- New decay reaching the root canal system
- A leaking or damaged crown or filling
- Persistent bacteria inside the tooth
Retreatment involves carefully reopening the tooth, removing the previous filling material, cleaning the canal system again, and resealing the tooth.
Our goal is to address the source of the problem while preserving your natural tooth whenever possible.
