Go with your heart. Think about what you will be doing after school...
Ding ding ding^
OP, There's a whole lot of threads on this if you run a search. I guess pod and dent are similar in that your scope is fairly narrow and students start progressing towards their specialty right away. The scopes could not be more different, though. The schooling processes are designed and focused so that graduates are pretty much stuck in that scope unless they want to go back to school again, so I agree to go with your heart and definetly pick the field that interests you and you want to work in for 40+ years. Your best bet is to do some shadowing and see which field appears to you more.
Yes, most general dentists or orthodontists don't take any hospital call, but if you want to be an OMax surgeon (seems all pre-dents and most dental students do), I will tell you that those guys get called into the ER pretty frequently for facial traumas. For general dentists, you could also consider the long term effects of flouridated water and better tooth care. I've never had a cavity in my life, and neither has my fiancee or many of our friends. 30 or 40 years ago, that was virtually unheard of. Just one or two cleanings per year really doesn't pay too well. Yes, newer elective cosmetic dentistry procedures might make up for some of the decline in cavities and more routine needed procedures, but to what degree? OTC WhiteStrips or just 99 cent Hydrogen Peroxide whiten teeth enough for most people's standards. Competition for dental patients might only get stiffer in the future. Dent is one of the few medical specialties that I notice doing a fair amount of advertising. When I go in for a cleaning, my dentist's office features a TV looping a video ad about the cosmetic procedures his office offers while I'm in the waiting room for him to come in and read my x-rays. Is that good business or trying to use patients' insecurity to make them buck up for a pricy elective procedure? Tough to say...
Podiatry has its downsides also, but it's not like diabetics are going to learn how to prevent neuropathy and arteriosclerosis, women are going to cease wearing high heels, geriatrics are going to suddenly learn how to prevent their toenails from growing, or athletes are going to stop injuring their feet.
Then again, it's a lot easier to ignore heel or toe pain than it is to go to work everyday with a yellow or busted up grill
Personally, if I wasn't going into podiatry, I'd choose nursing. I enjoy being in the hospital on at least some of my work days, and some of my hard working friends have had great success in the field. Nursing provides nice income, tremendous flexibility in specialty and locations of job offers, and higher graduate degrees (MS, PhD, CRNA, NP, etc) if one wants to work for them down the line.
