Endodontics (Root Canal Therapy)


Painless root canal treatment to restore broken, infected and painful teeth.


Commonly known as a root canal treatment, endodontics involves saving a diseased tooth by removing the root pulp and replacing it with bio-grade rubber filling.

The endodontist removes the inflamed or infected pulp and carefully cleans and shapes the root canal. The space inside the canal is then filled and sealed. Following this, you will return to your general dentist for a crown or permanent filling to protect the tooth and to restore it to full function.

  • What does the procedure involve?

    The treatment is carried out in comfort and without pain under local anaesthetic while you are awake. You are always in control and should there be any discomfort at any time, the cause would be immediately dealt with before continuing treatment.

    When the tooth is numb, it is then "isolated" with a small sheet of rubber called rubber dam which is held in place by a small clip. This barrier stops water, debris, filling materials and disinfectants getting to the back of your mouth and throat. You can breathe, swallow and move your tongue normally throughout the whole procedure!

    Under an operating microscope, an opening is then made through the top of the tooth to find the root canals and any decay is also removed at this stage. When found, to remove the inflamed or infected pulp tissue within, the canals are carefully cleaned and shaped with very small instruments and disinfectant fluids. When the root canals have been cleaned and shaped, the space is then filled with a biocompatible material called gutta percha (a type of rubber) and a cement to ensure complete sealing. A temporary filling is then placed to seal the opening. This temporary filling will be removed by your dentist when the tooth is restored.

  • When is endodontic treatment necessary?

    Endodontic treatment treats the inside of the tooth and becomes necessary following irreversible damage to the pulp. This can occur due to infection entering the tooth via decay, cracks, fractures and broken fillings. Infection may also gain access as a result of periodontal (‘gum’) disease or trauma. If this is left untreated, an abscess can develop. Symptoms and signs to look for include spontaneous pain, prolonged sensitivity to hot or cold, tenderness to touch and chewing, and tooth discolouration. Sometimes the nearby gum tissues may be swollen and tender. Occasionally, there are no symptoms.
