Root Canal


Inside a tooth is a fine space called the root canal. The root canal contains the dental pulp which consists of nerves and blood vessels. If the dental pulp becomes diseased or dies, a toothache or an abscess may occur. In the past these problem teeth were extracted, but now your dentist can offer you root canal treatment to care for these teeth.

  • Is root canal treatment painful?

    Local anaesthetic and modern painkillers are used to provide comfortable treatment. Usually painful symptoms improve once treatment is started.

  • How is a tooth restored following root canal treatment?

    It is very important that any restoration adequately seals the root filling from infection by bacteria in the mouth. Teeth requiring root canal treatment often have large fillings or extensive damage and will require a crown to restore them properly. These teeth are also weaker and becomes brittle and the added protection of a crown is recommended.

  • How successful is root canal treatment?

    If the root canals are able to be fully cleaned and sealed and the tooth properly restored, then treatment has a very high success rate. The treatment may take several visits to complete with temporary fillings and dressings placed in the tooth between visits. Antibiotics are sometimes prescribed when an infection is present.

  • What complications can occur during root canal treatment?

    Because the root canals are very fine and curved in some teeth, it may be difficult to clean the canals completely. Occasionally a piece of a file may break off in the root canal due to the strain placed on these fine instruments. Sometimes these are retrievable, but they may also be sealed in the root canal as part of the filling. Pain or discomfort may occur between appointments due to on-going tenderness of the tissues around the tooth, or a flare-up of an abscess or a hair-line crack in the root.

  • What is the cost?

    The cost vary and our dentist will give you an estimate after a thorough examination. The cost will depend on the difficulty and the time spent treating the tooth.
