Root Canal Retreatment

Why is root canal retreatment required?

With proper care, even teeth that have had root canal treatment can last a lifetime.  But sometimes, a tooth that has been treated doesn't heal properly and can become painful or diseased months or even years after treatment.  If your tooth failed to heal or develops new problems, you have a second chance.  An additional procedure may be able to support healing and save your tooth. 

Occasionally what happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:

  •  Narrow or curved canals were not treated during the initial procedure
  • Complicated canal anatomy went undetected in the first procedure
  • The placement of the crown or other restoration was delayed following the endodontic treatment
  • The restoration did not prevent salivary contamination to the inside of the tooth

In other cases, a new problem can jeopardize a tooth that was successfully treated:

  • New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth
  • A loose, cracked or broken crown or filling can expose the tooth to new infection
  • A tooth sustains a fracture


What does root canal retreatment involve?



 During treatment, Dr. Forte will reopen your tooth and remove the filling materials that were placed in the root canals during the first procedure.  Dr. Forte then carefully examines the tooth, looking for additional canals or cracks.  Dr. Forte then removes any infection, cleans and shapes the canals, and places new filling materials.  The opening is then sealed with a temporary filling.  Once the tooth heals, a new crown or other restoration is placed on the tooth to protect it.  

You will then 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 it to full function.
