If decay is left untreated, the infection can spread to the nerve inside of your tooth causing a painful hole in your tooth known as an abscess. When this happens, Dr. Kaplan will have to perform a root canal correcting the problem and reliving you of discomfort and pain. A successful root canal will allow you to keep the infected tooth rather then removing the tooth completely.
Underneath the layers of hard enamel on your tooth is what is known as a root canal system. It is full of a soft substance known as pulp, which is made of nerves and blood vessels. If the pulp gets infected it can form an abscess which can cause swelling inside your tooth. A root canal is when Dr. Kaplan removes the infected or dead pulp from inside your tooth.
