A root canal is a common dental procedure designed to save a severely damaged or infected tooth by removing the infected pulp and nerves from its interior. This treatment is essential when a tooth’s pulp becomes infected due to deep decay, a cracked tooth, or trauma. Without a root canal, the infection can spread, leading to severe pain, abscess formation, and ultimately, tooth loss. Root canals are highly effective at preserving the natural tooth structure and preventing the need for extraction.
