Root canal treatment, also known as endodontic therapy, is a dental procedure aimed at treating infected or damaged pulp within the tooth's root canal system. The procedure involves removing the infected or damaged tissue, cleaning and disinfecting the canal, and then sealing it to prevent further infection. Root canal treatment helps to alleviate pain, save the natural tooth, and restore oral health. It is typically recommended when a tooth's pulp becomes inflamed or infected due to deep decay, trauma, or other factors.
