Dentistry has true to introduce an assistant level which can do basic dentistry, but so far as I recall this movement has only been successful I Minnesota? New Hampshire wants to try it out too, but generally dentists fear the profession will suffer from a perception of "dentistry light" and impact their business.
I can't imagine letting anyone take a drill to my teeth but the most skilled DMD I can afford to pay. I'm surprised others don't feel that way (but hey, whatever floats your boat).
