United is proud to offer the Comfort H/S™ Bite Splint. This innovative bruxism solution eliminates the negative side effects of clenching and grinding, including wear on natural teeth, jaw aches, and headaches. The Comfort H/S™ Bite Splint provides the best of both hard and soft night guards. It includes a 1mm soft, polyurethane inner layer and a 3mm hard, copolyester outer layer. The inner lining allows the bite splint to rest comfortably against the teeth and sensitive gums, while the outer layer protects against mild to extreme bruxism.
