I am gonna have to strongly disagree with you on this one. IMHO if you wouldn't consider dentistry if you didn't live in those four specific states your heart isn't in it and you should get out while you still can.
The parts of your post I bolded are especially telling. I don't mean offense but come on, you would apply to dental school with a bio degree and a 3.1? What exactly is that supposed to mean? I would only expect that kind of dig on my pre-med colleagues, not someone who wants to go into the profession.
Nursing and being a hygienist are not in the same stratosphere as being a dentist in terms of the nature of the job. I understand that more people are going corporate/settling to stay on as an associate but dentistry is supposed to attract people who in general don't like the prospect of working for/being limited by a boss as well as people who understand that they can maximize their earnings when they are in control of the buisness vs collecting a paycheck. I also call into question whether the ROI of being a hygienist of the course of an average adult life span is actually higher than the ROI of being a dentist, even if you go to one of the expensive schools.
I'm not offended at all!
Let me explain a little bit if how I think though.
Every profession is a means for you to make a living. And why do we spend our time to make a living? So that we can do exactly that, live. So when it comes down to it, lifestyle is a very important piece of the puzzle to me. I have no disillusions of becoming a 10+ millionaire or anything like, but dentistry does allow a nice lifestyle, so I had it on my potential careers, along with all medicine, finance, and Psych I/O.
Then I considered the actual nature of the job. Could I see myself working 80+ weeks to make a decent to great income? No because then that living I wanted disappears if you think about it.
Could I see myself as a psychiatrist (my goal job heading to college) giving medication to patients I would have preferred to help in other ways, and very rarely seeing them succeed in their treatment for mental issues? No I couldn't live with that.
So it left medical school, dentistry, and my dad's job that starts at 65k + a 15k sign on and caps off at 130k in around 4-6 years. I loved dentistry and all the different aspects, and after putting in the lot years to residency and things like that, plus the extra enjoyment vs medicine I picked dentistry over applying med.
That being said if I'm honest I wanted to do my dad's job and he told me no...
So there's my mindset. I don't feel "called" into dentistry or anything like that. It's a profession, one I do happen to really like, bit a profession all the same.
I like dentistry the most, but I also like medicine, nursing, hygiene, psych careers, and all the other jobs out there. So if any of them combined to give more worth in my mind to dentistry i would have done them.
Autonomy, owning a business, that stuff is part of the pie, I wouldn't risk everything for it though.
