It is almost always cheaper to purchase medical services and pharmaceuticals outside the US that, frankly, I'm surprised *more* Americans don't do it. Even in Singapore, Southeast Asia's most expensive country, it costs between $50-100 to get a deep clean done. Just across the border in Malaysia, it might be between $30-60. Thailand's about the same. In fact, you'd be hard-pressed to find any place in *Asia* that charges as much as $275 for a clean.

For more extensive but non-urgent, medical procedures, you could probably fly from the continental US to Bangkok, get the procedure done, spend two weeks in a spa resort with lots of golf, sunshine, buy all the medicine you need for a year, and fly back to the US, and still have some spare change compared with getting it all done in the US.
