Root Canal Therapy is used to treat teeth that have become infected or begun to decay on the inside of the tooth where the nerve is located. The nerve is what gives the tooth feeling and blood supply. When it becomes inflamed or irritated from a cavity or trauma and dies, it must be treated or abscesses may form around the tooth causing immense pain and even further damage thus resulting in tooth extraction. Treatment involves cleaning out the inside of the tooth and sealing it so the tooth can be saved, filled and restored to its full function.
Root canal therapy is highly effective, less expensive than tooth extraction, helps to maintain your "bite" alignment and usually lasts a lifetime unless new infections threaten and are cause for retreatment.
