> think of all the years of unnecessary education they'd pile on to dentistry and the bottle necks they would put up to raise the wages to MD level.

That seems more an indictment of the medical education system than the insurance system. There are already parallel medical education systems in the US (MD vs. DO, although there is little practical difference). Seeing either type of physician is treated equally by health insurance. Why can't health insurance also cover DDS visits as well?

Uh, not exactly. MDs and DOs do receive different sorts of education, and insurance can distinguish between them.
