Endodontic Retreatment

Sometimes it is necessary to re-do root canal treatment, usually if an infection occurs after the initial treatment. The procedure typically involves re-opening the tooth and removing the old root filling material, sterilising and then re-sealing the root canal. This is a more complicated procedure and requires advanced techniques to achieve the best result. Dr. Harlamb uses specialised technology and experience to perform endodontic retreatment procedures.

Improper healing may be caused by:

  • Curved or narrow canals that were not treated 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 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, Dr. Harlamb 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. Dr. Harlamb will clean the canals and carefully examine the inside of the problematic tooth. Once cleaned, Dr. Harlamb will fill and seal the canals and place a temporary filling in the tooth.

At this point, Dr. Harlamb will advise you when you will need to return to your dentist to have a new crown or restoration placed on the tooth to restore full functionality.
