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 Retreatment may be needed.
Improper healing may be caused by:
- Curved or calcified canals were unable to be treated during the initial treatment.
- Complicated canals 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.
Fractures existing in the root structure.
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 retreatment has been selected as a potential solution to your problem, the doctor will re-open your tooth to gain access to the root canal filling material. This restorative material will be removed to enable access to the root canals. The doctor will now re-clean your canals and carefully examine the inside of the problematic tooth. Once cleaned, the doctor will fill and seal the canals and place a temporary filling in the access opening.
After a week or two, you will need to return to your dentist in order to have a new crown or restoration placed to restore the tooth to full functionality.
