Our teeth are meant to last a lifetime. Sometimes, however, damage occurs to a tooth (often from a deep cavity or an injury that causes a tooth to crack) and the inside of the tooth becomes infected. This infection damages the pulp of the tooth – the network of blood vessels and nerves inside.
Left untreated, the damaged pulp can cause infection that will damage the bone around the tooth and cause swelling and pain. If the damaged tooth becomes infected, your dentist, or a dental specialist called an Endodontist, may have to perform an endodontic treatment (often called Root Canal Therapy) to save it.
Endodontic treatment involves opening the tooth, removing the damaged pulp, cleaning, shaping, filling and sealing the tooth. Depending upon how much infection there is in the injured tooth, your may be put on medicine before your dentist or Endodontist can begin to work. Your dentist or Endodontist will start by getting the tooth ready.
