Endodontics
Endodontic treatment - more commonly known as root canal treatment - involves treating an infection or inflammation of the tooth pulp or the tissues that surround the root of a tooth.
What is pulp?
Pulp is the soft tissue located deep inside a tooth, underneath the enamel and dentine. It extends all the way from the root to the crown and is made up of nerves, blood vessels and connective tissues.
If the pulp become inflammed or infected, root canal treatment may be used to save the tooth.
Causes and symptoms
Infection or inflamation of the pulp can be caused by many factors, including:
› a deep cavity or or breakdown of a filling or crown
› a crack or chip in the tooth
› an accident or trauma
› periodontal or gum disease
› repeated dental work or extreme wear-and-tear
Symptoms may include:
› swelling and/or pain in the gums around the tooth
› sensitivity to hot or cold
› tooth discolouration
Root canal treatment
Root canal treatment may be used to save a tooth which has an inflammed or infected pulp.
To determine whether root canal treatment is appropriate, your dentist will examine the tooth and may take an x-ray. Some dentists may complete the root canal treatment or you may be referred to a specialist, called an endodontist.
If you proceed with treatment, a local anaesthetic will be given to reduce pain. A dental drill is used to provide access to the pulp. A specially designed file is then used to remove the damaged pulp, as well as cleaned, enlarged and re-shape the root canal. Any infection may also be treated with anti-inflammatory, anti-bacterial or antibiotic medications. Treatment may require several visits to the dentist so a temporary filling will be used to protect the tooth between visits. To complete the treatment, the root canal(s) are filled with a plastic-like substance to seal the pulp chamber.
Root canal treatment may leave the tooth more susceptible to fracture, in which case, a crown may be used to protect and strengthen the tooth. A post may also be used to support a crown if the tooth lacks structure. A crown will also help to restore function and cosmetic appearance.
Benefits of root canal treatment
Root canal treatment can save a tooth which has an infected or inflammed pulp. If left untreated, pain and abscesses may occur, and this can damage the bone surrounding the tooth. Ultimately, extraction may be required. Usually, people prefer to repair and save a tooth rather than have it extracted. A natural tooth will generally be stronger and function more effectively than an artificial tooth. If treatment is successful, a treated tooth may last for many years or possibly, the rest of your life.
