A root canal treatment, often referred to simply as a "root canal," is a dental procedure designed to treat infection or damage within the pulp of a tooth, which is the soft tissue inside the tooth containing nerves and blood vessels. When the pulp becomes infected due to deep decay, a crack, or trauma, it can cause severe pain and potentially lead to an abscess if left untreated.

Root canal treatment, also known as endodontic therapy, is a dental procedure used to treat infection at the center of a tooth (the root canal system). The treatment involves removing the infected or damaged pulp, cleaning and disinfecting the canal, and then filling and sealing it to prevent further infection.
