Details
Replacement night guards - both custom from your dentist and OTC - are qualified medical expenses. Night guards wear out over time and need periodic replacement. Whether you're replacing a $40 OTC guard or a $500 custom guard, the cost is eligible. Same rules as the original purchase: it's for treating bruxism or TMJ.
