Usually people make life decisions based on personal experience. Something as simple as Dr. X was a really awesome person and I really enjoyed doing what he does or Dr Y is a terrible person and I hate what they were doing to their patients. This is why shadowing is essential before picking a direction.
You are right dentists and dental hygienists have really cornered the tooth market. Very few MDs will touch the mouth. Dentistry is more popular today than it has been in years in terms of money and "prestige". However, as the dental forums will tell you. Not everything is rosy on the dentist side of things (saturation, general vs. surgical - have to pick one or the other, compensation issues,...). I would be careful reading too many websites or comparing stats b/c stats can be very misleading and people usually use whatever statistic supports their case and dismiss stats that are inconvenient.
You might not have to worry about the MD/DO's just the 5,000+/yr dental graduates you have to compete against. Compare this to the 550 podiatrists. There are more dental surgeons than podiatric surgeons in the US). Also you are right a Family Doctor could address the nail infection and a surgeon could address a bone problem, but no hospital is going to let a family doctor operate, and no surgeon is about to prescribe foot cream any time soon. Podiatrist can bring the two together in a part of the body that generally none of the afore mentioned professions want to touch. When was the last time your primary care doctor looked at your foot? Even if your a diabetic I watched an endocrinologist completely ignore the foot during her 30 minute session, even though I could smell an odor. I asked what was that odor on the patients way out, they checked, OH surprise surprise she has gangreen her foot is rotting and she can't feel it. Podiatry, it's a nitch. A neglected part of the body that 1 MD recognized 110 years ago.
Prestige - A prestigious career in 2010 can be complete hog wash in 2020. Look at crime scene investigators 30 years ago, looking at mutilated corpses was not popular at all, 80+ episodes of CSI and a couple of hot chicks and dudes (if your into that) later now the market is flooded with CSI students.
Final food for thought, when I was shadowing doctors...
MD Family Med, god PA is pushing me out of a job, 2 yrs and they are equal to me, I might have to sign off for them but I have to report to my supervisor at the hospital who is a PA with an MHA, go be a PA ->
PA god I hate taking orders, working hourly and discovering ive been laid off for no reason go be an RN they are more established and people know what they are...
RN are you kidding me? I have the same problems as a PA, I have to take orders and clean bed pans and work in nursing homes to get my first job, and I may never even break out of nursing homes until i have 10 yrs under my belt, APRN is hard to achieve and its almost impossible to get into the lucrative jobs (Anesthesiologist..Emergency Room...) go be a DO they are just like MD doctors...
DO, OMM is not recognized by many insurance agencies AND 90% of my fellow DOs don't bother practicing it, I always have to explain what my degree is, its damn hard to get a surgical residency, you think we are all equal? Try telling that to the Match, god go be a dentist ->
Dentist -> You thought all dentists could get a surgical residency LOL! No I am a general dentist despite graduating in the top 20% of my class. Its not too bad except that I don't get the same respect and people still think I am not a "real doctor" and good luck trying to be the PI on a research paper the mighty Ph.D.'s will treat you like ****. Go be a podiatrist, the busiest physician in the state is a podiatrist you have to book months in advance to see him...
Podiatrist -> I am tired of defending/defining what DPM is for everyone, I am a real doctor too, some people think all I do is clip nails or day, I am trained in surgery but wish I could practice my full scope in every state and get equal reimbursement to an MD, sigh, if I could do things over...I would be an MD.
And the Cycle continues...
<P.S. I cut out
OD - over saturated, low compensation, and a feeling of being professional eye glass vendors
Pharm.D. - Wallgreens vs. Walmart anyone? I don't make 100k just starting but my school cost a ton? Why are there are a TON of Pharm. D. programs out there?
DPT - We were 2 yrs now we are turning into 4 year programs, but what did we gain? We are not MDs and most of us make <100k a year.
I will spare you the rants of Chiropractors (I could type here all day)
I could go on and on with other health care professions ranging from Radiation Therapists, Neutricianists, Genetic Councilers, Medical Technicians, Biomedical Technicians, CLS, Coders...
Point Is: NOBODY IS HAPPY. Not even the $400,000 Orthodpedic Suregon who took 8 years of 40-60k/yr being propped up by her/his hubby/wifes salary during that time trying to pay off the same $200k, 300k, or 400k debt we all have to pay.
You know maybe I missed my calling, maybe I should have been a career councilor...hmmmm
