If you enroll in the company's dental DMO plan, orthodontia is at least partially covered. I have a son who is going to need braces soon so I've just started looking into it. I know the DMO plan is a much bigger pain in the a**, like an HMO, but depending on how much it covers for braces, it may or may not be worth it. I haven't researched enough to figure that out yet though. I figured I'll look closer during open enrollment.
