Root canal treatment is a dental procedure performed to treat a tooth with a diseased or infected pulp, the innermost part of the tooth containing nerves and blood vessels. The treatment involves removing the infected pulp, cleaning and disinfecting the root canals, and then filling and sealing the space with a biocompatible material. This helps to prevent further infection and save the tooth from extraction. The procedure is typically carried out under local anesthesia to ensure the patient’s comfort. After root canal treatment, a dental crown may be placed on the treated tooth to restore its strength and functionality. Root canal therapy is crucial for alleviating pain, preserving natural teeth, and promoting long-term oral health.
