Root Canal Therapy

Root Canal Therapy

Root canal therapy, also known as endodontic therapy, is a dental treatment for removing the diseased or damaged pulp (nerve) of the tooth. After the removal of a damaged tooth, the inside areas of the nerve chambers or root canals are filled and sealed.


  • As a first step, local anesthesia is administered to the tooth which is to be treated.
  • After the tooth and the surrounding area becomes numb, the endodontist drills an opening through the crown or the biting surface of the tooth to access the pulp chamber.
  • Using specially created files the endodontist cleans out the infected, diseased and dead pulp from the canals.
  • Once the infected and dead tissue removed, the canals are disinfected using disinfectants.
  • The canals are shaped with fine instruments so that they can be filled with the root canal fillings known as gutta-percha and sealed.
  • Temporary cover material is placed above the gutta-percha.
  • Sometimes, a post is placed into the canal next to the gutta-percha to give the crown more support.
  • Finally, the crown is cemented in place so that it never dislodged.


  • Prevents infection from spreading and save the tooth from extraction.
  • Relieves pain caused due to inflammation.

This procedure is done by a root canal specialist or an endodontist. Fortunately, the procedure is not always as painful as you might expect and you can return to your normal day-to-day activities shortly after the procedure. Follow after-care instructions carefully to promote adequate and proper healing. A follow-up can help to evaluate and detect possible problems and treat them before they get worse.
