That's amazing, and I shudder to think that it will EVER happen for two specific reasons.
(1) Dentists are in no way shape or form qualified to be primary medical care providers. At its onset, dentistry was narrowly rejected as a specialty of medicine - I believe because too much training was involved for the number of dentists needed. Anyway, can you imagine dentists having to completely retrain and re-equip their offices just so they can deal with ingrown toenails and stomachaches? It's ridiculous to assume a dentist can replace a primary care physician - just as it's ridiulous to assume a physician could do the job of the dentist - entirely different skills are involved. Even though the basic science work is similar for medical and dental school, dentists are not trained to do physicals (nor is their focus at all on anatomy below the head and neck) any more than physicians are trained to do a cavity prep. Apples and oranges are still fruit, just as DDS's and MD's are both medical professionals, but you can't begin to pretend they're the same.
(2) Dentists have thus far been successful in preventing managed care from fouling up patient care as it has with the bulk of the medical world. I can't imagine the ADA lobbists would ever let lawmakers pass such a ridiculous law, or that dentists would coroperate with it. It's difficult enough to find a dentist that will accept public aid, now imagine trying to convince a dentist to retrain at her own expense, re-equip her office/operatories for medical exams, and to jeopardize her dental patient base by cramming the appointment slots with medicare health exams.
It's a fascinating idea, but if dentists had WANTED to be doctors, then they would have gone to medical school.
I agree completely that the medical system in the U.S. is headed for crisis status. From what I've seen, they're doing a decent job of recruiting new nursing students (judged by the TV ads for nursing, enrollment and everyone wanting to hire them). They don't even need to put for the same effort to recruit new med. students -- if another medical school would open in the US - be it MD, DO, PA or whatever - they would have NO trouble filling the enrollement slots, and in a few years could be producing a lot more qualified primary care physicians, rather than politicians simply flipping through the phone book to see who else they could get to help clean up the managed care mess. There are a lot of smart people involved in this situation - I'm certain they can come up with a better idea than this one...
great topic, btw
