Root canal therapy

Reasons for root canal therapy

Root canal treatment (endodontic therapy) is called for when decay or a fracture has exposed the tooth pulp (nerve) to bacteria in the mouth. An infections results and pus is generated in the pulp chamber. Left untreated, the infection will spread to the bone around the tooth.
In the beginning there may be little or no pain involved with this condition. It is when the infection reached the pulp (nerve and blood supply) that the pressure builds and that is when the pain can become severe.

What is the object of root canal therapy?

The object of root canal therapy is to clean the tooth completely all the way to the tip (apex), removing the infected pulp. The pulp chamber and canals are then thoroughly cleaned and filled, usually with gutta percha. If the infected pulp is dead, there should be very little, if any, pain attached to the procedure. However, a certain amount of sensitivity from the bone around the tooth is normal.
