Root Canal Retreatment

Endodontic Re treatment

Occasionally a tooth that has undergone endodontic treatment fails to heal or pain continues despite therapy. Although rare, sometimes a tooth initially responds to root canal therapy but becomes painful or diseased months or years later. When either of these situations occur, the tooth often can be maintained with a second endodontic treatment.

Previous endodontic treatment that has failed may be best dealt with by a specialist. Failures may be due to blockages, ledges and perforations within the root. Sometimes it is necessary to remove posts, fractured instruments as well as existing root filling materials to access the failed treatment.


Endodontic therapy when done properly usually has a very high degree of success.  We will discuss with you the chances of success for your specific tooth, before any endodontic procedure is started to help you make an informed decision.

However, it should be remembered that it is impossible to guarantee the success of any medical procedure.Even with the best treatment, healing may not occur due to circumstances beyond the control of the dentist. Should this occur, further steps may be required to deal with the infection.

Once endodontic therapy is completed your tooth should  be examined and X rayed after 6 – 12 months. This allows us to make sure the tooth has healed or is healing properly. If needed it will examined periodically up to 2 years.
