Annie, I wear a bruxism appliance (on lower teeth). Suprisingly, my dental insurance DID NOT COVER IT but my regular HEALTH INSURANCE DID. Thanks to a great receptionist who really checked into things for me. Talk to your dental receptionist or call your regular health insurance and see what the chances are that it can be covered by them. If it is a chronic health issue and not just a dental problem they may help pay for things.
