Boy oh boy.... do you need to learn a few things
Money will not buy a License to Practice Dentistry. At least not in any of the major markets like Califorinia or New York. Perhaps in Arkansas or Mississippi or Montana, but I doubt it.
They have these nasty things called Boards, Certification Boards, that must be passed in order to practice. No amount of money can get you a pass grade on those. Do you have any idea of the costs of malpractice insurance these days? Over 5 billion dollars in premiums have to be paid, just for insurance!
Unless you are blind or stupid, just take a look at any Russians teeth. They are famous for poor work-due in part to the lack of modern techniques, and in part because the "system" did not really stimulate advances in a field not considered to be of a national priority.
Americans do pay a lot for dental care, but a lot of what they have to pay is covered by health insurance, too. They also have a fanatic interest in good teeth and good appearence.
The Dominican Republic, right now, offers excellent dental care, no ifs ands or buts. You might have to look around a bit', but you can find excellent dentists. And the prices are reasonable.
FYI, the DR is sending dentists to Spain to teach the Spanish modern techniques. The universities here are receiving dozens of medical personnel to be trained as dentists for Spain.
Many people do not know that there is an extremely close relationship between the WHO and the PanAmHO, especially in regards to medicine and dentistry...And between DR universities and universities in the States in these two fields......
And, to the point, there is no need for a Russian Dentist to come and practice here.....Sorry, for that....
Now if he were an expert in mining, agriculture or manufacturing perhaps he could find work...
