Root canal treatment is carried out when the pulp inside the tooth becomes inflamed or damaged due to bacteria. In most cases it causes severe pain but sometimes there is no sign of pain or swelling. If the tooth is left untreated then the infection can form an abscess on the tissue around the supporting bone.
The endodontic procedure involves removing bacteria from inside the tooth and the root canals. Once they have been cleaned the root canals are sealed and the tooth is then repaired with a filling or a crown. Before treatment commences, the patient will be anaesthetised so that the procedure is painless. After treatment the tooth may be sensitive but this is a highly successful dental treatment and only a small percentage of patients may in the UK experience a mild flare up around the tooth.
