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 return or continue to exist. Sometimes, the pain may occur months or years after treatment. If so, endodontic retreatment. may be indicated.

Improper healing may be caused by:

    • Curved or narrow canals that were not treated adequately 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 that did not prevent bacteria from contaminating the inside of the tooth.

Inflamed Tissue


Filling Removed


Canals Cleaned


Root Material Placed


Filling Restored


Healed 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 retreatment has been selected as a solution to your problem, the doctor will reopen your tooth to gain access to the root canal filling material. The old root canal restorative material will be removed to enable access to the root canal spaces again. The doctor will now 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 tooth.

At this point, you will need to return to your dentist within a month or so, once your tooth is feeling better, in order to have a new crown or restoration placed on the tooth to restore full functionality.
