$16,000 in dental care, what should I do? Stay in U.S. and pay it, or get treatment in a different country?

Hey folks. I just signed some paperwork a few weeks ago to get pretty much my whole mouth taken care of. I have some pretty messed up teeth, and the total will be about $16,000 (at $400 a month). Now, I'm only 24 years old, and I don't need this kind of debt. I was planning on possibly moving to London for several other reasons sometime next year. So is it a rational idea to think that I should tell these guys to stop the treatment where they're at right now, and I'll just pay for what they've done, and then just have the remainder of the work done in London, where it would be FREE? Also, would there be any legal problems involved with any of this?

Chances are, if you signed the paperwork, you'll still have to pay for it. Try to get out of it, but if they still insist, it's better to get a dental plan through a site like http://dentalplansaver.com and pay 80$ a year...it should save a lot of that money. Good Luck!
