Root Canal Treatment

Root canal therapy is a treatment modality that will save diseased or injured teeth. The alternative to endodontics is extraction. Typically, a severely decayed tooth will begin to ache. The pain might be intermittent at first and over time progress to a constant dull throbbing pain or a severe ache that might be felt radiating to all the teeth of the affected side. Sometimes there is no pain and an abscess might be discovered on a routine x-ray or intraoral examination.

The pulp is a soft tissue that is located inside the tooth structure. It contains nerves, arteries, veins and lymphatic supplies. These are located in the canals which are thin tube like spaces in the roots and in the pulp chamber located within the crown of the tooth.

When the pulp is diseased or injured and unable to repair itself, it becomes infected. Left untreated, the pulp will die and become necrotic. Infection can build up at the root tip forming an abscess that can destroy the bone surrounding the tooth. Endodontic treatment is the removal of the diseased pulp tissue, which will enable the body’s defense system to repair the damage caused by the infection. Root canal therapy normally takes two to four visits to complete.


• A local anaesthetic is used so the procedure will be pain free.

• An opening is then made through the top of the tooth into the pulp chamber.

• The pulp is removed from the pulp chamber and the root canals are cleaned, enlarged, and shaped to a form that can be filled and sealed later.

• A temporary filling is placed in the opening of the tooth to seal it between visits. There can be some discomfort in the area of the tooth for a day or two following the initial visit.

• A permanent filler is finally filled inside the tooth to prevent future damage.These fillers prevent any percolation of food,saliva or bacterial entries,thus gradually causing the infection to die out.

• A crown is later placed over the tooth to prevent future fracture of the treated tooth.
