Root Canal Treatment Sydney NSW

It used to be that if a tooth was infected, or the nerve in the tooth was dying, the tooth would have to be extracted. Root canal treatment provides a much more sustainable solution.

Root canal treatment, also known as root canal therapy, removes the injured nerve from the tooth. This helps to alleviate the symptoms without resulting in loss of the tooth. When it comes to caring for the oral health of our patients, a solution that can avoid tooth extraction is always the best option for the patient.

Causes and symptoms of an infected root canal

A common cause for the need of root canal treatment is an infected or abscessed tooth. Infected tooth pulp can be caused by a deep cavity or old filling, periodontal disease, or even a fractured tooth. Sometimes trauma like a sharp blow to the mouth can result in damage to the pulp (nerve) of the tooth. If you are experiencing any of the following symptoms, book an appointment with our team as soon as possible.

Possible symptoms of an infected root canal:

  • Sensitivity to cold or hot liquids
  • Tooth sensitivity to sweets
  • Tooth pain from biting pressure
  • Spontaneous, constant or intermittent tooth pain
  • Severe or throbbing tooth pain
  • Swollen, tender gums
  • Appearance of abscesses

Root canal treatment – the procedure

Root canal treatment removes the pulp tissue – the so called ‘nerve’ – from within the tooth. After all this material has been removed, the canal (or canals if it is a multi-rooted tooth) is sterilised and sealed with a material that prevents bacteria from re-entering and infecting the canals. Sometimes the entire procedure is completed in one visit, but more commonly it will be spread over two visits.

We use ‘state-of-the-art’ instruments and techniques to perform this comfortably and efficiently. The short video on this page explains a little about this procedure. Once we are satisfied that the tooth is clear of infection, we will then seal and fill the root canal system with a permanent material to prevent reinfection of the canal(s).

This completes the actual ‘root canal therapy’ for the tooth, but the tooth itself must then be properly restored to make it strong and functional for the long term. This can be achieved in a variety of ways – sometimes just a simple filling will suffice, but more commonly a crown or onlay will be required to help prevent the tooth from fracturing as time goes on.

Invest in your oral health and well-being

Root canal therapy restores an unhealthy tooth to a state of health and comfort for the patient, however the tooth is now somewhat more brittle and prone to breakage. It is for this reason that your dentist will usually recommend that a root canal treated tooth be restored with a crown or onlay so as to help protect it from breakage. This particularly applies to molars (back teeth) which bear most of the forces during chewing. Your dentist will provide you with all the information you need prior to commencing your root canal treatment.
