Health Insurance covering the cost of braces?

I'm just wondering if there is anyone out there that has had health insurance cover their braces. My husband is major need of teeth repair, and he has broken through the upper lip on both side from different things. - - - he's dental insurance will cover 1/2 of it, i was just wondering in health insurance ever considered covering braces. He has two different dental plans, if health insurance doesn't cover it, could the other plan (through military) cover the other 1/2? thanks for any answers~

See if the health insurance will pay for it, IF IT IS medically required (dr authorizes it, as for his physical well being/necessary)
