Get a job with a company that offers family health insurance. Often this results in lower income. Often one spouse works for the insurance and the other has the job for parnassah.
With Obamacare you should have less trouble getting insurance, but it might cost a lot.
Remember that braces are in most cases a luxury that only the best insurance covers. If the family is beyond childbearing years (i.e. mother well past 40), and no one has a serious problem, high deductible policies might be cheaper (for most families the only big ticket item is childbirth). One can also go uninsured (at least until Obamacare kicks in) and try to wrangle cheaper prices for doctors who get paid in full up front (rather than the doctors having to do their own wrangling with insurance companies). With no insurance or a high deductible policy, health savings accounts become practical. Rigging a flexible savings account can also cut the costs by about a third (if you live in a high tax state).
