Root canal treatment is a dental procedure used to save a tooth that is infected or damaged. During the treatment, a dentist removes the infected pulp from the inside of the tooth, cleans the area, and fills it with a special material to prevent further infection. This helps to relieve pain and restore the tooth's function. After the procedure, the tooth may need a crown or filling to protect it and restore its shape. Dentists typically recommend root canal treatment to avoid tooth extraction and maintain overall dental health. Proper care, including regular brushing and flossing, is essential for the longevity of the treated tooth.
