Most of the check-ups and dental work I've ever had have been at facilities serving a large population with special, highly developed programs for international visitors, i.e., medical tourists. In Bangkok, Bumrungrad Hospital is perhaps the most famous in the world built on this model, serving Gulf and Ozzie patients in great numbers and specialized to their needs (in the later case, a rubber mallet...) A check-up there is like being run thru a white padded assembly line built into a four star hotel, and it works wonderfully, though prices have crept up even as the baht has declined (it's American run, but still much cheaper than the absurd US). In contrast, the medical check-up facility at CIMA Hospital in Escazu, Costa Rica, was in a nice little hospital and conducted by a series of fine professionals, but I was the only patient that morning. My point is, size matters (though Bumrungrad is rumored to have got it's start offering, er, 'extreme size reduction' surgery decades ago). Unless medical and/or dental facilities lakeside offer high-value services at sufficient volume, i.e., successful medical tourism, someone is going to end up paying for any improvement in facilities, though demographic trends should help.
