Many people think of dentists as the providers who drill and fill your teeth when you have a cavity. It's true that this is part of their job, but it is only one small piece of what they do. Dentists also provide cleaning services. They can put a crown on a badly cracked or damaged tooth, and they can perform a root canal if the delicate tissues inside your tooth become infected.
