Your teeth that have had endodontic treatment will last as long as other natural teeth if you are taking the appropriate care. Yet, a tooth that has received treatment may fail to heal or pain may continue to exist. Sometimes, months or years after treatment the pain may occur. If this is the case, Endodontic Retreatment may be needed.


Improper healing may be caused by:

  • Complicated canals went undetected during the initial treatment

  • Curved or narrow canals were not treated during the initial treatment

  • The crown or restoration did not prevent saliva from contaminating the inside of the tooth

  • The crown or restoration was not placed within the appropriate amount of time following the procedure


In some cases, new problems can influence a tooth that was successfully treated:

  • A cracked or loose filling or crown can expose the tooth to new infection

  • New decay can expose a root canal filling material, causing infection


If retreatment has been selected as a solution to your problem,to gain access to the root canal filling material the doctor will reopen your tooth. This restorative material will be removed to enable access to the root canal. The doctor will now clean your canals and examine the inside of the problematic tooth then will fill and seal the canals and place a temporary filling in the tooth. 

In order to have a new crown or restoration placed on the tooth to restore full functionality you will need to return to your dentist as soon as possible.
