If your tooth nerve chamber becomes infected by decay, or damaged by trauma, root canal treatment is often the only way to save your tooth. Inside the hard outer shell of each tooth is a specialized area called the pulp, or nerve chamber. It contains a system of blood vessels, lymph vessels and nerves. The pulp, which enter from the bone through the root canals, is the system that provides nourishment for the cells within the tooth. Deep tooth decay or other injury can cause damage to or infection of the tooth pulp. In a root canal or endodonic treatment , the dentist removes the damaged or infected pulp and replaces it with a special filler which helps maintain tooth structure. Step 1: After the tooth is anesthetized, an opening is made through the crown into the pulp chamber. Step 2: The length of the root canal is determined. Step 3: Unhealthy pulp is removed. Canals are cleaned, enlarged, and shaped Step 4: Canals are filed and sealed. A metal post may be added for structural support or to retain restorative materials Step 5: The tooth is sealed with a temporary filling.
					Usually a gold or porcelain crown adds further protection. The material used to fill the root canal will probably last a lifetime, but eventually the filling or crown may need replaced
