Root Canal is an area of dentistry concerned with the tooth pulp (the soft inner tissue of the tooth) and the tissues surrounding the root. The various treatment procedures done in Endodontics are Root Canal, Pulpotomy, Apicoectomy etc.
Root canal, is performed to save a tooth when the pulp (which is made up of the nerves and blood vessels etc.), becomes infected or damaged. This can be due to caries, injury, gum infection etc. For many people who experience tooth pain or discomfort in the tooth, Root Canal Therapy is recommended. For this treatment an opening is made into the tooth, the diseased or dead pulp tissue is removed, the pulp chamber and root canals are cleaned, sterilized and filled, thus sealing the root canals. The treatment is comfortable and pain free.
After root canal treatment, the tooth is still attached to the bone, just like any normal tooth and its function is not affected. Only the inside of the tooth loses the pulp tissue (which may be diseased or dead), during the treatment. A crown may be needed to protect the tooth from fracturing and to restore its esthetics.
