  • Root Canal Therapy FAQs

    What is a root canal?

    Underneath your tooth’s outer enamel and within the dentin is an area of soft tissue called the pulp. The pulp carries the tooth’s nerves,veins, arteries and lymph vessels. Root canals are very thin divisions that branch off from the top of the pulp chamber down to the tip of the root. A tooth has at least one and up to four main root canals.

    Why do I feel pain?

    When the pulp becomes infected due to a deep cavity or fracture that allows bacteria to seep in, or an injury due to trauma, it can die. Damaged or a dead pulp causes increased blood flow and cellular activity and pressure cannot be relieved from inside the tooth. Pain the tooth is commonly felt when biting down, chewing on it and applying hot and cold foods or drinks.

    Why do I need root canal therapy?

    Because the tooth will not heal by itself. Without treatment, the infection will spread, bone around the tooth will begin to degenerate, and the tooth may become loose. Pain usually worsens until you are forced to seek emergency dental treatment. The alternative to root canal therapy is extraction.

    The extraction of your tooth is often cheaper than root canal therapy. However, the replacement tooth to fill the space is considerably more expensive usually an implant or a bridge.

    What is involved in root canal therapy?

    Once tests confirm that you need root canal treatment one of our Dentists would normally carry this out for you. If the treatment is complex we may recommend that you see a specialist.

    After local anaesthetic the tooth is isolated using rubber dam. This is to keep any bacteria in your saliva out of the tooth as well as containing any fluids and medicaments we need to use during treatment. Access is then made into the infected / damaged pulp chamber and this is cleaned of all diseased tissue and shaped so it can be filled. This can take anywhere between one and three appointments depending on the tooth. If multiple appointments are required the tooth is sealed with a temporary filling between visits.

    On the final visit the root canals are filled with a rubber root filling material to prevent re-contamination. A core filling or restoration is placed directly over this to seal your tooth. Finally a porcelain or gold crown or onlay is placed over the tooth to protect it from fracture.

    What are the risks and complications?

    The success rates of root canal therapy treatment is best when infection is treated early. Where there is a lot of existing infection and resulting bone loss the prognosis is significantly reduced.

    Other complicating factors can be the presence of lateral canals not always visible on x-rays and instrument separation during treatment. Both of these rarely occur but may require extra treatment if they do.

    There a higher risk of tooth fracture in root filled teeth compared to vital teeth which is why we recommend a crown straight after root canal therapy. It is not always possible to crown a tooth after it has fractured, especially if the fracture line is below the gum level or through the middle of the tooth.
