Root Canal (Endodontic) Retreatment

You may have been referred to our office for root canal retreatment. Occasionally a root canal may need to be redone. As endodontists, Drs. Sullivan and Suhag have advanced training and have access to specialized equipment including the use of the dental microscope.

Root canal retreatment may be required for any of the following reasons:

• 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 filling or crown 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.
