Root Canal Retreatment

Occasionally a tooth that has undergone endodontic treatment fails to heal or pain continues despite therapy. Although rare, sometimes a tooth initially responds to root canal therapy but becomes painful or diseased months or years later. A tooth may not heal as expected following initial treatment for a variety of reasons:

  • calcified or curved canals were not treated during the initial procedure

  • complicated anatomy went untreated in the first procedure

  • delay in placement of the crown or final restoration following the initial endodontic treatment

  • the restoration did not seal the inside of the tooth prevention salivary contamination

In other cases, a new problem can arise causing a previously successfully treated tooth to fail.

  • new decay, recurrent decay, can expose the root canal filling to bacteria, causing a new infection in the tooth

  • a loose or broken crown or filling can allow salivary contamination inside the tooth leading to a new infection

  • the tooth sustains a fracture

Your tooth will be reopened to gain access to the root canal filling material. Inside of your tooth will be carefully searching for additional canals or unusual anatomy that requires treatment. 

After cleaning the canals, a filling will be placed to seal the canals.

After retreatment is completed, it is essential for you to return to your dentist as soon as possible to have a new crown or restoration placed to protect and restore to tooth to its full function.
