Root canal treatment is a therapy used to save a tooth that is deeply decayed or infected. When the pulp, which is the nerves and blood vessels inside the tooth, becomes inflamed or diseased, it must be removed in order to alleviate discomfort and save the tooth. If the infected pulp is not removed, pain and swelling can result, and your tooth may have to be removed.
Most of the time, a root canal is a relatively simple procedure with little or no discomfort involving one to two visits. We remove the diseased tissue, carefully clean and disinfect the inside of the tooth and roots, and fill it with a rubber like material called gutta percha. The tooth is then restored with a filling or a crown for protection.
