Root Canal Treatment Sydney

Root canal treatment (endodontic treatment) is a procedure involving the replacement of a tooth’s damaged or infected pulp (nerve) with a filling. There are many reasons that can lead to disease or damage to dental pulp. Some of these include:

  • Untreated dental decay
  • Deep filling
  • Trauma to the tooth
  • Habitual grinding of tooth (bruxism)
  • Advanced gum disease

Root canal treatment is carried out when a tooth dies, or is infected. Often this forms an abscess that can be painful, while at times the problem can remain asymptomatic for many years.

During root canal treatment, the dentist will medicate and clean out decay, pus and bacteria within the root canal which is flushed and removed under anaesthetic. This procedure may be repeated several visits until the tooth is free of bacteria. The infection free root canal is then sealed with filling material. In back teeth where there is a considerable loss of tooth structure a dental crown may be required to reinforce the tooth.

If the tooth pulp is left untreated the infection may spread which can cause painful abscess, facial swelling, localised bone loss and ultimately loss of the tooth. The success rate of root canals are about 90-95%.
