Endodontic retreatment

What is endodontic retreatment?

With the appropriate care, teeth that have had endodontic treatment will last as long as other natural teeth. Yet, a tooth that has received treatment may fail to heal or pain may continue to exist. Sometimes, the 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 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

Once revisionary treatment has been selected as a solution to your problem, the endodontist will reopen your tooth to gain access to the root canal filling material. This restorative material will be removed to enable access to the root canal. The endodontist will now clean your canals and carefully examine the inside of the problematic tooth. Once cleaned, the endodontist will fill and seal the canals and place a temporary filling in the tooth. Next your dentist will place a new crown or restoration on the tooth to restore full functionality.
