If your tooth does not heal correctly after a root canal procedure, endodontic retreatment may be necessary to save it. With any dental procedure, it is better to save your natural tooth if the possibility is there. A “retreated” tooth can last a very long time, even a lifetime.
A few instances that require the need for endodontic retreatment:
- The infection in your tooth did not heal properly
- Placement of your crown or other restoration was delayed
- New decay has formed
If your endodontist thinks you need retreatment, you both will discuss treatment options and choose the one that best suits your situation. Your endodontist will begin by reopening your tooth to gain access to the root canal filling material. Removal of restoration and filling material allows access to blocked canals. After removing the canal filling, the endodontist will clean the canals and carefully examine the inside of your tooth using magnification and illumination, searching for any additional canals or unusual anatomy that requires treatment. Your endodontist will then clean the canals, seal them, and place a temporary filling in the tooth. After your endodontist completes retreatment, you will need to return to your dentist as soon as possible to have a new crown or other restoration placed on the tooth to protect and restore it to its full function.
