Root canal is so popular in the field of endodontics that at times an endodontic treatment is used as a synonym to mean the other. Pulp forms the core of natural tooth. Tooth decay and injury can open up way for bacteria to reach the pulp of the tooth. An infected pulp can cause serious problems in oral health. Root canal treatment is performed to remove the infected pulp and fill the area with appropriate material. Gutta-percha and core build up material are used in order to protect the natural tooth. Root canal process is performed by endodontists and experienced dentists. Local anaesthesia is used during the procedure for painless treatment.
