They won't know but you would have to be pretty convincing when they ask, "Why dentistry, pharmacy, etc?"
If you want to be a doctor, do your best to do that, as the other professions you mention are very different.
To the other poster: As for "being the boss", you can do that in dentistry, pharmacy, pod, and others. What are you referring to?
I know people go into professional schools for various reasons (including money) and there isn't anything wrong with that IMHO; people want stable careers with a good lifestyle. The important thing is to be honest with yourself and your reasons for doing it and definitely know what you're getting into. If it is for the money, remember that you are helping patients too and that is part of your job! You should do your best to fulfill that.
Unfortunately, to get into any professional school, you have to jump through a bunch of hoops that are mainly BS. Fortunately, a lot of the pre-reqs are the same.
