Root Canal Treatment

Root canal treatment (also called endodontics) is needed when a large cavity in a tooth reaches the nerve chamber, or when a tooth breaks. The infected nerve needs to be removed and the space filled. A root filling will often allow you to keep a tooth which would otherwise have to be extracted and replaced with a bridge, denture or implant.

If a large cavity in a tooth reaches the nerve chamber, or if a tooth breaks, bacteria can cause the nerve to die. The root canals become infected and an abscess may form beneath the root(s) in the jawbone. Pain may occur at anytime during this process, and the infection can spread.

Treatment is usually carried out over 1 or 2 visits. The purpose of the treatment is to remove the bacteria and dying tissue from inside the tooth and to clean and disinfect the root canals. This is achieved by making a small hole through the tooth into the pulp chamber, locating and measuring the root canals, then cleaning and widening them using fine instruments. Local anaesthetic is used throughout the process so it is not painful.

Root treatments on back teeth are more complicated because they have a number of roots and magnification may be used to aid the instrumentation of these intricate canals in the tooth.

The canals are then filled and sealed with a modified rubber base material called “gutta percha” to prevent re-infection.

Due to lack of lack of blood supply to the tooth, the tooth can become weak and fracture relatively easy. It is usually recommended that a Crown be provided as the final restoration to strengthen the tooth.
