Root Canal Therapy
Endodontic treatment is necessary when the pulp becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth or a crack or chip in the tooth. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess. Signs of pulp damage include pain, prolonged sensitivity to heat or cold, discoloration of the tooth and swelling and tenderness in the nearby gums. Sometimes, there are no symptoms.
Root Canal Retreatment
With proper care, most teeth that have had endodontic (root canal) treatment can last as long as other natural teeth. In some cases, however, a tooth that has received endodontic treatment fails to heal. Occasionally, the tooth becomes painful or diseased months or even years after successful treatment. If your tooth has failed to heal or has developed new problems, you have a second chance. Another endodontic procedure may be able to save your tooth.
In this procedure, the endodontist opens the gum tissue near the tooth to see the underlying bone and to remove any inflamed or infected tissue. The very end of the root is also removed. A small filling may be placed to seal the end of the root canal. This is termed “Retrofilling,” and a few stitches or sutures are placed in the gum to help the tissue heal properly.
