I'm going to have to get a root canal done. What should I expect?

Root canals are usually performed by a dentist or endodontist, who will numb the area around the tooth and then remove the infected tissue. They may also clean out any remaining debris from the canal and replace it with gutta percha, which is a rubber-like substance that seals off the inside of the canal. Afterward, you'll need to wait for the area to heal before getting the crown placed back on the tooth.
