What is root canal?
Root canal treatment or endodontics is used to save the tooth when the dental pulp (blood vessel and nerve in the centre of the tooth) dies and the tooth become infected. The cause of infection is usually decay in the tooth, under the filling or in the fracture of the tooth. Without treatment, this can cause a dental abscess resulting in pain, swelling and infection of the jaw bone.
The only alternative to carrying out root canal treatment is to remove the tooth. Altough some people would prefer an extraction, it is usually best to keep as many natural teeth as possible. Before surgery, you may given antibiotics to control any infection that has gone beyond the tooth to the bone.
When the pulp of the tooth is dying or has died, the pulp chamber becomes infected. The body's own natural defences cannot fight the infection because no circulation remains in the tooth. Root canal treatment is used to open up the pulp chamber, clean up the infected remains of the pulp and feel the chamber with an inert (non-active) material to prevent the infection returning.
What to excpect?
After the dentist numb your tooth, the dentist may use a rubber dam to keep the tooth area dry and free of saliva. A rubber dam is simply a piece of rubber that fits over the tooth and isolates it from the rest of the mouth. The dentist will then prepare the tooth by drilling an opening. After the dentist remove all the decay and bacteria, the dentist will use root canal files to clean out the canals (roots) of the tooth.
Root canal files are small instruments that increase in diameter and fit down into the canals enabling the dentist to remove the pulp of the tooth.
Some dentists like to wait a week or two before they finish a root canal, to make sure that there is no discomfort or further infection. If this is the case, the dentist will thoroughly clean the tooth and ussualy put some soothing medicine inside and seal it closed with a temporary filling material.
At the final stage of a root canal teratment, the dentist will usually fill the canals with a rubber filling material called gutta percha. After the canals are filled, a regular filling will be placed in the tooth.
