Dentistry is a rather hard field to get into because of the years of costly education required in the U.S. State-subsidized schools are somewhat less expensive. You have to be good in the sciences and also have excellent ability working with your hands and it helps to be artistic. You need excellent communication abilities as you need to discuss treatment plans with patients and be able to work well with staff members. A lot of dentists own their own practices and this requires a lot of business management skills as well. There are frustrations with the field, such as patients who cancel appointments at the last minute or fail to show up, and this means you don't get paid and also have to cover the overhead costs for that time lost. Overall, the income potential is fairly good in most communities. Another big disadvantage to the field is licensure. Each state has their own licensing board and it can be extremely difficult to move to another state and may require retaking licening board examinations, which involve written as well as clinical tests on patients. Also, licensing boards can be very biased and I was a victim of the Maine Board of Dental Examiners, which blamed me for the actions of one of their own members, so I was forced out of the state and my practice destroyed. So I lost the investment I'd made in my practice as well as my home and community, etc. So for me it has not worked out to be a good career choice. Until the system is reformed, I'd be very careful going in to dentistry, but if you do, be aware of the adverse effect that licensure can have.
