With the appropriate care, your 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 Re-treatment may be needed.
Improper healing may be caused by:
- Curved or narrow canals that were not, or could not, be treated during the initial treatment.
- Complicated canals or additional 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 bacteria 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 re-treatment has been selected as a solution to your problem, the doctors 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 doctors will now clean your canals and carefully examine the inside of the problematic tooth. Once cleaned, the doctors will disinfect or medicate the tooth, fill and seal the canals inside the tooth, and place a temporary or final filling in the opening made in the biting surface of the tooth.
At this point, you will need to return to your dentist as soon as directed in order to have a new crown or alternate final restoration placed on the tooth to restore full functionality.
