When a tooth becomes damaged or decayed into its pulp, a root canal is often advised to preserve the tooth’s structure. Root canal therapy, also known as endodontic therapy, is designed to ultimately save a tooth from needing to be extracted in the future. The procedure removes the inflamed or infected tissue within the tooth root, which is then restored with a filling or covered with a dental crown. Although root canals may seem intimidating to many people, the procedure is typically very straightforward and actually reduces tooth pain, swelling, and sensitivity.
