A root canal is a dental procedure that is performed to repair and save a tooth that is infected or damaged in its pulp, which is the soft tissue inside the tooth. The pulp contains nerves, blood vessels, and connective tissue, and if it becomes infected or inflamed, it can cause severe pain and lead to further dental problems if left untreated.
During a root canal procedure, the dentist will remove the infected or damaged pulp from the tooth, clean the root canal thoroughly, and then fill and seal the space to prevent further infection or damage. The procedure typically involves multiple appointments, depending on the severity of the tooth decay or infection.

Root canals are usually performed under local anesthesia, and the procedure is relatively painless. After the procedure, patients may experience some mild discomfort or sensitivity for a few days, but this can be managed with over-the-counter pain medication.

Root canals are a common and safe dental procedure and have a high success rate. They can help prevent the need for more extensive dental procedures such as extractions or dental implants. However, it is important to note that the success of a root canal depends on several factors, including the severity of the damage, the location of the tooth, and the patient's overall oral health.

If you are experiencing tooth pain or other symptoms of a dental problem, it is important to see a dentist as soon as possible to determine the best course of treatment, which may include a root canal.
