Root canal treatment, also known as endodontic treatment, refers to removing the damaged or infected essence (pulp) of a tooth, disinfecting the tooth, and then sealing it with filler again. The pulp, located in the innermost part of the tooth, can be considered a soft core. Nerves, blood vessels and connective tissue are found in the pulp that extends to the root tip of the teeth. In cases where the tooth cracks as a result of any impact or a deep caries occurs, bacteria enter the pulp and begin to multiply here. If this condition is left untreated, the bacteria can cause a serious infection or dental abscess, leading to bone or tooth loss along with pulp death. In such a case, root canal treatment is applied to the cracked or decayed tooth to save the tooth.
