With the appropriate care, endodontically treated teeth 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. This 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 was not properly sealed and did not prevent saliva from contaminating the inside of the root.
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 restoration can expose the tooth to new infection.
Once retreatment has been selected as a solution to your problem, the doctors will reopen your tooth to gain access to the root canal filling material. The old root canal filling material will be removed to enable access to the root canal. The doctors will now clean your canals and carefully examine the inside of the problematic tooth. Once cleaned, the doctors fill and seal the canals and place a temporary filling in the tooth.
At this point, 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.
