This procedure is needed when the nerve of a tooth is affected by decay or infection. It is the treatment of choice to save a tooth, that otherwise would die and have to be removed. With modern dental technology, you won't believe what we can restore and how painlessly this can be. 

1. Why save a tooth? 
      a. Teeth continue to shift for a lifetime. If you loose a tooth, the opposing teeth will get longer and the adjacent teeth will tilt. 
 2. Why does a tooth need a root canal
      a. Trauma to the tooth and nerve
      b. Large Cavities
      c. Previously placed large fillings 
      d. Injuries to tooth and supporting structures
      e. FRACTURES
 3. What is a root canal? 
       First, the teeth are hollow. This hollow space holds the blood vessels and nerves. When they are damaged or infected, the veins and blood vessels must be removed. After removing the infected blood vessels and nerves, the hollow housing is filled with a special dental material to seal to the tip of the root. A crown should then be placed to protect and seal the biting surface of the tooth. If this is left untreated, the tooth would develop an abscess (infection) . This abscess could have potential medical complications, especially for patients with heart valves, heart murmur, or artificial joints. 
1. Prolonged cold pain and/ or persistent hot pain (longer than 1-2 minutes)
2. Biting pain 
      Pain that keeps you awake at night, that is sensitive to touch, swelling or tenderness around the root of the tooth, such as a gum boil
