Endodontic Retreatment
When a patient continues to have pain, discomfort, or signs of infection after having a root canal procedure, a retreatment procedure may be needed.
Schedule an AppointmentReasons for Endodontic Retreatment
Some common reasons for a previously treated tooth to become re-infected include:
- Canals not located or cleaned during the initial root canal
- Bacterial leakage back into the root canal system from broken or missing fillings
- Cavities exposing the previous root canal material
- Cracks or fractures of the roots
If you have recently had a root canal procedure from one of our endodontists, home care instructions can be found here. For more information on root canal retreatment, visit the American Association of Endodontists Webpage by clicking here.

What Happens During Root Canal Retreatment?
Root canal retreatment involves exposing the root canal system, examining inside the root canal system with the surgical operating microscope for untreated canals, signs of infection, and fractures. The endodontist will remove the old root canal filling, then clean, disinfect, and re-seal all canals. A temporary filling will be placed and then the patient will have a follow up appointment with their primary dentist.
