My uncle is a Dentist. He is a dental surgeon. He helps prevent disease of the oral cavity.
Oh thats interesting, Ive wanted to become a dentist but dont know too much about it. Can you tell me if it requires a college degree? 
It does. A dentist completes a lot of schooling. There is a dental team with technicians, hygienists, and therapists. 
Yeah thats what I thought, id have to get alot of years of practice, What is a dentists salary anyways? 
It depends on the area I am sure. A crazy fact about dentists is that in France and China barbers were first to perform dentistry.
Ah OK. Wow barbers? who would have thought that a person who cuts hair can be a dentists haha, When was the first dentists anyways? Have humans always had dentists around? 
This was around 1400. France ended this practice of barbers being dentists.
