Inside each tooth is a pulp chamber that contains the nerves and blood supply for the tooth. When the pulp becomes infected due to decay or injury to the tooth, the pulp must be removed from the center of the tooth and the canals of each root. Once the infected pulp is removed, the remaining chamber is filled with a rubber-based material to seal it off.
The procedure starts with removing the decay and creating access to the pulp chamber. The chamber and canals are then thoroughly cleaned and back filled with a rubber-based material. A “build-up” is placed to replace tooth structure removed for root canal. A new crown is then cemented over build-up.
A root canal is needed when a tooth is infected or sick due to decay or injury, chronic tooth pain is experienced from contact with hot and cold liquids, pain is experienced from pressure or biting down, or there is a danger of infection spreading.
Root canal therapy is an excellent way to save a tooth that would otherwise die and need to be removed.
