A root canal is a dental procedure aimed at salvaging a severely damaged or infected tooth. Typically performed by a specialist endodontist, this treatment involves removing infected pulp from Inside the tooth, disinfecting the canal, and subsequently sealing it to prevent further infection. Root canals are crucial for preserving the structure and function of the affected tooth, alleviating pain, and preventing the spread of infection to surrounding tissues. This procedure is often a last resort to save a tooth from extraction, offering patients a means to maintain their natural smile and oral health.
