Root Canal Treatment

Root canal is the treatment of the disease or injury to the pulp. 
The pulp is the soft tissue inside the tooth that contains blood vessels and nerves. When the pulp becomes inflamed or infected, treatment is needed. The most common cause of pulp inflammation or infection are a cracked or chipped tooth, or deep cavity or filling, or other serious injury to the tooth. All of these can allow bacteria to enter the pulp. 

Why should the pulp be removed?
If damaged or infected pulp is not removed, the tissues around the root of the tooth can become infected. Pain and swelling often results. Even if there is no pain, bacteria can damage the bone that holds the tooth in the jaw. Without treatment the tooth may have to be removed. 

What does treatment involve?
Root canal treatment can involve one or more dental visits. An opening is made through the crown of the tooth into the pulp chamber. The tooth’s nerve or pulp is removed from the pulp chamber and root canal (the space inside the root). Each root canal is cleaned and shaped so it can be filled. Medicine may need to be placed for a period of time to help get rid of bacteria. Then the canals are filled to get a seal. Most of root canals teeth then have to be covered by a crown for protection.
