The tooth saver

Root canal treatment is the only means of saving a tooth where the nerves and blood vessels (the pulp) within the tooth have been damaged or died. The damage may have been caused by deep decay, a crack or trauma – even years later. Left untreated or delayed too long, it can cause severe pain, facial swelling and possible tooth loss.

Reasons and causes

  • Root canal (endodontic) treatment can save a damaged* tooth
  • Treatment required when the pulp becomes inflamed or infected
  • Without the treatment, abscesses may form leading to a loss of tooth
  • Infection causes include: deep decay, repeated procedures on a tooth, cracked or chipped teeth
  • Trauma such as severe impact can cause death of the nerves

Treatment procedure

  • Local anaesthetic and relaxing gas for your comfort
  • Removal of the bacteria and infected soft tissue of root canals
  • Cleaning and disinfecting root canals and pulp chamber
  • Filling and sealing of the root canals and pulp chamber
  • Treated tooth can be strengthened and protected with a crown
  • Complex cases may be referred to a specialist endodontist

*Endodontic treatment is the only means to save a tooth in which the nerves and blood vessels within the tooth have been damaged or have died.
