Root canal therapy is the process of removing infected, injured or dead pulp from your tooth. The space inside the hard layers of each tooth is called the root canal system. This system is filled with soft dental pulp made up of nerves and blood vessels. When tooth decay occurs, this pulp can become inflamed and infected, causing pain and discomfort. To relieve this pain and to save your tooth root canal therapy is necessary.
A root canal treatment is usually completed in one to three visits. During the first visit, a small hole is drilled through the top of the tooth and into the inner chamber. The diseased tissue is removed, the inner chamber cleansed and disinfected, and the tiny canals reshaped. Then your dentist will fill the chamber and canals with an elastic material designed to prevent infection. If necessary, the drilled hole is temporarily filled until a permanent seal is made with a crown.
