Pros and Cons of a Dentistry degree?

I was wondering what I could expect from a Dentistry degree, how competitive it is to get onto the course? The likelihood of a job after the degree? And anything else that would be useful to know.

Well, in order to become a dental hygienist, you must earn at least an associate's degree. This will require at least two years of classes, and possibly summer courses. Many schools offer a bachelor's program, which includes four years of instruction. While both choices are acceptable, a bachelor's degree can mean more job opportunities and higher pay.
