Root canal treatment is a dental job used to get rid of infections of the tooth’s pulp, which is the part of the tooth that contains the blood supply and other important elements. If the infection is left untreated it can potentially spread and develop into an abscess, which is a pus filled area that can cause aching in the tissues around the teeth. If it spreads to the bone the tooth may come loose. Root canal treatment involves the necessity to take out the infected pulp tissue and substitute it with a natural type of rubber called gutta percha.
