What is a root canal?
Below the hard enamel and dentine of your tooth is a mass of tissue called pulp, which surrounds the nerves at the center of your tooth. Pulp is sensitive to bacteria. If it becomes exposed to potential infectants — for example, if you have a crack or chip in your tooth — pulp can become infected. An untreated root canal infection 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.
