What is a root canal?
Inside your tooth, below the hard enamel and dentin, is a mass of tissue called pulp. The pulp surrounds the nerves at the center of your tooth and it is sensitive to bacteria. If the pulp becomes exposed to potential infectants or bacteria — for example, if you have a crack or chip in your tooth — pulp can become infected. An untreated infection of the pulp can lead to pain, dental decay, and even tooth loss.
Root canal therapy is the process of removing the infected pulp from the center of your tooth. It is a non-surgical procedure that requires your dentist to make a small opening to remove the rotten tissue. The center of your tooth is then filled with a root canal filling.
