Re-root Canal Treatment

Re-root Canal Treatment

Re-root canal treatment is performed in an attempt to save the tooth from extraction. Restoring the natural tooth often produces healthier results, and many re-treated teeth can function very well for years, perhaps even for the rest of the patient’s life.


  • During re-treatment, the damaged tooth is reopened to gain access to the root canal filling. It involves deconstructing the crowns, posts and other restorative materials in order to reach the root of the tooth.
  • Later the filling material from the initial procedure is removed and the canals are thoroughly cleaned.
  • Using magnification and illumination, the affected area will be carefully examined to detect possible additional canals or unusual areas.
  • After the canals are cleaned well, the tooth is refilled with gutta-percha, and the canals are sealed.
  • A temporary filling is placed in the tooth. This procedure is done under local anesthesia, which numbs the affected area and relieves any pain and discomfort. The anesthesia also helps patients relax.
  • Regular dentist appointments will be required to permanently restore, using a crown or other material, the tooth, allowing it to function fully, and protecting it against future infection or decay.


  • Preservation of damaged tooth.
  • Retaining natural bite and smile.
  • Prevention of future dental damages.
  • Virtually pain-free procedure.

After root canal retreatment, patients may experience tenderness, pain, and discomfort, the dentist should be contacted. Patients can minimize these risks by following the pre- and post-procedure instructions.
