Root canal therapy is an advanced procedure to save a tooth, which a number of years ago would have been extracted. Root Canal Therapy is normally required when a tooth has died, usually as a result of a large amount of previous decay or trauma.
The typical symptoms are pain and swelling which unless treated will get worse and is known as an abscess. However, sometimes a dead tooth can be completely symptom free and may only be identified on an x-ray. By using very fine and flexible instruments and magnification, the narrow canal inside the teeth can be cleaned of all infected material and shaped to accept a plastic based filling material. This may take a number of visits.
Once the canal system has sealed, a permanent restoration can be placed on top.
