Root Canal Therapy

Root canal therapy is the process by which we remove the inner nerve of a tooth because it has an infection or is inflamed. This is usually caused by decay, disease or injury.

Root canal therapy relieves pain and saves a tooth that without treatment can cause irreparable bone and gum damage and may end with the tooth needing to be removed. A tooth can have as few as one or up to four root canals, sometimes more. Root canal therapy has a very high success rate of over 95% and with anaesthetic (such as sleep dentistry) and specially developed instruments can be completed comfortably.

With the development of modern techniques this treatment is generally completed in 2 appointments. Once completed the tooth has no nerve and is no longer alive. It will still function as a normal tooth and must be cared for in the same way as your other teeth.

Sometimes when a tooth has undergone root canal therapy there is a need to remove a portion of its structure. In these cases it may be necessary to place a supportive metal post to provide the tooth with additional strength. Placement of a crown over your treated tooth will restore strength, form and function of the tooth.

You may experience some mild discomfort for several days following your procedure. This can be alleviated with over-the-counter pain relief medication. A follow-up exam may be advised to monitor your progress. For further details, please contact us on (02) 9635 5166. Our well designed practice is located at 77 Marion St Harris Park NSW 2150.

Root canal therapy can save badly infected teeth from extraction, and a fully restored tooth can last for many years or even for life. Prompt treatment helps prevent the spread of bacteria as they can destroy the jawbone. It is less expensive to have root canal therapy than to replace an extracted tooth, and treatment is relatively comfortable as Painfree Dentistry uses up-to-date techniques.


After root canal therapy the tooth can become more brittle and prone to fracturing. Not all teeth respond well to root canal treatment, and occasionally therapy will fail and the tooth will become re-infected. It may be possible to re-treat the tooth, but sometimes extraction will be the only viable option.
