Root canal treatment, also known as endodontic treatment, is the process of removing infected, injured or dead pulp from your tooth.
When bacteria (germs) enter your tooth through deep cavities, cracks or compromised fillings, your tooth can become abscessed. An abscessed tooth is a tooth with an infection in the pulp. If the pulp becomes infected, it needs to be removed. An abscessed tooth may cause pain and/or swelling. Your dentist may notice the infection from a dental x-ray or from other changes with the tooth. If left untreated, an abscessed tooth can cause serious health problems. After root canal treatment, it is often recommended that a crown be placed to restore the full functionality of the tooth.
