There is a reason general dentistry is separate from, say, the duties of a physician. The teeth are a very unique part of the body. They are in fact the only exposed bones we have, and that makes their care something that takes a great deal of skill and knowledge.
Dentists go to school for a long time to learn that knowledge and develop that skill. Without a dentist's care, it is all too easy for a set of teeth to fall into disrepair, rot, and cause health problems that can extend throughout the body. Here are some of the duties involved in general dentistry.

One of the main roles of general dentistry and professionals in the field is to perform maintenance and diagnostics on their patients. Because regular cleaning benefits the teeth so well and because problems can arise very quickly, the ADA recommends going in for a checkup and cleaning every six months.
After diagnosing a problem, the next task involved in general dentistry is to cope with the procedures of some kind. For a cavity, that procedure could be anything from a filling to a root canal to extracting the tooth altogether. For a cracked tooth, the procedure could be implementing a crown. For missing teeth, the answer could be dentures or dental implants.
