<human>: I'm going to have to get a root canal done. What should I expect?
<bot>: Root canals are generally performed by a dentist or endodontist, and involve removing the infected pulp from your tooth. The dentist will then clean and disinfect the area, before filling it with a special material called gutta percha. This is usually followed up with a crown or cap to protect the tooth. You may experience some discomfort during treatment, but most people find that it's well worth it in the long run.
