Root canal treatment (also referred to as root canal therapy or endodontic therapy) is made necessary when a cavity is allowed, through neglect, to reach all the way to this pulp. (Regular cleanings and checkups prevent and detect problems early) Sometimes deep restorations or trauma to a tooth may cause the nerve to be damaged to the point it needs root canal therapy, also. Once this occurs the pulp becomes infected, and can even extend through the root tip and begin to eat away at the surrounding bone (this is an abscess). By the time the pulp is infected it must be treated, and cannot heal on its own. It can even weaken the entire immune system. This is dangerous, not to mention very painful. Symptoms that the pulp has become infected may include sensitivity to hot/cold or sweets, pain, swelling, pain to biting or pressure, and a bad taste in the mouth. Sometimes, however, no symptoms are apparent and the person is unaware of any problem until a checkup.
A root canal is then performed to clean out the infected tooth pulp, and disinfect the canals of the tooth. The only other treatment would be to extract the tooth. Once the infection is resolved, the canal(s) are filled in to prevent any further infection. Usually a core build-up and crown is recommended for restoring a tooth that has had root canal therapy.
Your dentist will take an x-ray of the tooth. If he or she determines that you need a root canal treatment, 1 or 2 appointments will be scheduled based on the size and duration of the abscess and other factors. Before starting root canal therapy, the doctor will administer local anesthesia to ensure your complete comfort. A dental dam is placed on the infected site to isolate the affected area. A small opening is made through the top of the tooth to gain access to the pulp. The pulp, which is the soft tissue inside the root canal, is removed from the chamber and canals. The canals are then cleaned with a disinfecting solution. X-rays may be taken throughout the procedure to ensure each canal is being adequately treated.
Once the canals are cleaned, they are filled with gutta percha, a rubber-like material to protect and seal. A temporary filling may be placed in the opening until it can be replaced by a permanent filling. After the root canal is completed, the tooth will need a crown to protect it from fracturing.
