  • Root Canal Therapy in Sydney

What is Root Canal Therapy?

  • Root canal therapy (RCT) is also known as endodontic treatment or root canal treatment
  • RCT involves the cleaning out (irrigation) and removal of infected or inflamed pulpal (nerve) tissues and the preparation of an empty nerve canal system to fill it in with a root canal filling (called gutta percha)
  • Root canal system contains pulpal tissues which consist of connective tissues, nerve and blood supply

Why RCT?

  • Severe toothache - that is not relief by pain killers (analgesics) and causes inability to sleep, chew & go on with daily activities
  • Deep decay affecting the nerve system
  • Symptoms of nerve pain and nerve inflammation that are irreversible due to dying nerve system
  • As a consequences of grinding habit
  • As a consequence of dental trauma or injury
  • As a consequence of long standing hairline cracks in the tooth which cause de-vitalisation of the tooth+/- root infection many years later
  • As a rare sequelae many years after orthodontics
  • Due to advanced gum disease
  • Tooth infection caused by either nerve inflammation, devitalisation or deep decays or a combination of factors

3 Types of RCT

  • for single-canal tooth such as anterior teeth (incisors and canines) and second premolars
  • for double-canal teeth such as first premolar and some lower anterior
  • for multi-rooted teeth such as all molars
  • RCT in anterior to premolars - simple, less expensive
  • RCT in molars - complex, more expensive. Therefore, patients will be given a choice to have them done either by a general dentist or by referral to a specialist endodontist

Benefits of RCT?

  • to eliminate the infection underneath the tooth
  • to save your natural tooth
  • can be quick and cost effective
  • can be comfortable if the tooth is completely anaesthetised and modern equipment are utilised

Disadvantages of RCT

  • RCT in molars are more complex, technique challenging hence take more time and requires at least 2 long appointments
  • RCT in molars are more expensive
  • RCT procedure in molars could run into more risks and complications than RCT in anterior-premolars
  • RCT is contra-indicated in patients who are unable to open their mouth wide enough for the comfortable insertion of the handpiece and small endodontic files.
  • You can still lose the tooth due to persistent pain or infection not resolved even after spending a lot of time and money on RCT
