What is a Root Canal?
Each tooth has tissue containing nerve fibers that run through the center of the root of your tooth, which are called “root canals.” When this tissue dies as a result of a deep cavity or trauma, root canal therapy is needed. Without treatment, the pain gradually worsens and the tooth can abscess and cause swelling.
What is Root Canal Therapy?
Root canal therapy is used to remove the dead tissue from the tooth. After numbing the area around the tooth, the dentist will isolate the tooth and sterilize it in order to protect it from bacteria in the mouth. The dentist then removes the dead tissue from the canals and fills those canals with a rubber filling material. The tooth is then built back up and prepared for a crown.
Years ago, completing a root canal would take several, long visits to the dentist. Today, root canals can often be completed in less than one hour during a single visit, thanks to recent advances in technology and new dental techniques.
