Endodontic Retreatment


What is a root canal 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.

Once endodontic retreatment has been chosen as a solution to your problem, Dr. Pablo Duluc Vega will reopen your tooth to gain access to the root canal filling material. The doctor will remove that material, clean the canals and then carefully examine the inside of the problematic tooth with a microscope. 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 as soon as possible in order to have a new crown or restoration placed on the tooth to restore full functionality.

Improper healing may be caused by:

  • 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.
  • Curved or narrow canals were unable to be treated during the initial treatment.
  • Complicated canals went undetected during the initial treatment.

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.
