With only half the U.S. population covered by dental insurance, Americans are flocking overseas for high-quality, low-cost dental care. The U.S. is facing a dental crisis. Only about 50% of the population has dental insurance, compared with the 85% who have medical benefits. Medicare doesn’t cover dental procedures, despite the fact that aging teeth are just like aging bodies—vulnerable and brittle. That means more and more patients will be traveling abroad to take care of their pearly whites.
