Endodontic Retreatment

With the appropriate care, your teeth that have had endodontic treatment will last as long as other natural teeth.  Yet, occasionally, a treated tooth may fail to heal completely or may develop new problems.  Pain may occur months or years after treatment.  If so, endodontic retreatment may be needed.

Improper healing may be caused by:

  • Curved or narrow canals that were not treated during the initial treatment.
  • Complicated canals that went undetected during the initial treatment.
  • The crown or restoration was not placed within the appropriate amount of time following the procedure.
  • The crown or restoration that did not prevent saliva from contaminating the inside of the tooth.

In some cases, new problems can influence a tooth that was successfully treated:

  • New decay can expose a root canal filling material, causing infection.
  • A cracked or loose filling or crown can expose the tooth to new infection.

Our doctors can diagnose the cause of post-endodontic disease and save such teeth by re-treating the root canal space. Advanced technology combined with our experience can give your tooth a second chance, thereby avoiding extraction.

After retreatment, you will need to return to your dentist as soon as possible in order to have a new crown or restoration placed on the tooth to restore full functionality.
