Endodontics is often the last form of treatment which can save a damaged or diseased tooth, which would otherwise have to be removed.
Root canal treatment involves the removal of the pulp (nerve) tissue from the tooth if it becomes inflamed or infected. This can be because of decay, a deep filling, a crack or fracture in the tooth or trauma.
Symptoms of pulp damage include pain, swelling or tenderness of the tooth or gum over the tooth, discolouration of the tooth or sensitivity to hot or cold. If left, the tooth could become increasingly painful and form an abscess.
Once the diseased nerve is removed and the root canals cleaned, the canals are sealed and a permanent filling placed. Often a crown is also advised, which helps seal and strengthen the tooth.
