A root canal is a dental procedure used to treat an infected or inflamed tooth. It involves removing the damaged or infected pulp from the tooth, cleaning and disinfecting the inside of the tooth, and filling it with a material called gutta-percha. The tooth is then sealed with a filling or crown to prevent further infection. The procedure is typically done to save a damaged or infected tooth from extraction. With the first incidence of pain root canal treatment will give a better result to retain the teeth for a longer period of time and prevent the infection from spreading further.
