I'm a dentist. I'm happy about it because that's what I wanted to be. I say that so you know there is no hidden agenda in my words.

When you go into a dentists office with a problem, you leave with resolution for the most part. You go to a physician's office and the only thing you get for your copay is your blood pressure and temperature taken and you get (under protest) weighed. Everything else you get sent out for and have to pay additional, more expensive (specialist) copays. When they send you for tests, when the results are forwarded back to your primary care physician, they have already been analyzed by the doctors there. All your PCP does is keep coordinate the activities. I once went to a MD to get my ear irrigated twice in 1 day and had to make 2 copays even though they were part of the same service.
