Endodontic Retreatment

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 narrow canals were not 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.



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. 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 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.

I would highly recommend Dr. Hsiao. He gave me excellent care; his assistant Jenn gave me excellent care and their personalities and bed side manners were great.

We had an excellent experience from start to finish with our daughter's root canal. We needed an emergency appointment...the staff worked hard to accomodate us and got us an appointment the next morning. Dr. Goldberg was excellent medically, and in dealing with our daughter who gets very nervous at the dentist! Worth the trip from over an hour away!!

The first root canal I had (NOT done by Dr Fuller or anyone at Endodontics) was a bad experience. My experience at Endodontics Limited, PC was easy. The receptionists who were my first impression, set the tone for a great experience, then to have met Dr Fuller and have is professionalism, patience and kindness completed my exceptional experience. The entire staff at the Phila office are fantastic. A huge thank you to all of them.
