I also know that Wyoming has a problem recruiting medical professionals across the board.
As for the midwest, I don't think we have much of a problem, not at least around here- in our general area (population of maybe 100,000) there are probably 60 dentists (including specialists) and you don't have a problem getting an appointment. Granted Terre Haute IN is listed as an "underserved" community for some reason by the NHSC, but I think that's just because a lot of the white trash around here never sees a dentist even though they have plenty of opportunities. Even the smaller towns (Sullivan, Brazil, Paris (IL), Marshall (IL), Greencastle, etc) around here all have dentists so I don't think we're underserved by any stretch of the imagination here. Maybe in the eyes of the public health authorities we are, but the issue I've seen around here is not a lack of dentists, but rather a lack of dental insurance or money to pay for the services of the dentists that are here. It doesn't help that a lot of the people around here who would rather spend any extra money they have on beer or a trip to the titty bar than on their kids teeth. It's a vicious cycle- the parents are uneducated and unkempt, and the kids turn out that way. Throwing more DDS's into the mix isn't going to fix things around here.
