Root Canal Therapy

Root Canal Treatment

Endodontic therapy or root canal treatment is a sequence of treatment for the infected pulp of a tooth, which results in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.


Performed well, root fillings can often be the difference between loosing or keeping a tooth.

What is Root Canal Treatment?

If you have an infection in your body your immune system, transported in your blood, will be drawn to the area where bacteria that have caused the infection can be destroyed and removed. The unique problem with infections of the root canals is that the blood vessels supplying the pulpal tissues have died. Therefore as there is no blood supply into the root canal there is also no immune system. This then allows a comfortable place for bacteria to reside safe from the bodies’ immune system that is trying to remove them.


By having the root canal treatment this is effectively doing your bodies’ work for you, as it cleans out all of the bacteria preventing any more coming in. This allows the body to then heal the tissues surrounding the tooth that have been damaged by the inflammation caused by the infection.
