MAXIMUM PROTECTION - Absorb-X Technology utilizes a very unique thermoplastic material to diffuse and absorb grinding forces, protecting the teeth from the pressure of grinding or clenching associated with bruxism. The mouthguards' perforations allow for a more natural saliva flow, critical to oral health. ULTRA THIN FOR SUPERIOR COMFORT - At only 1.6 mm thick, its sleek, lightweight design allows for total comfort while sleeping and doesn't impede speaking, drinking or breathing. No more clunky, chunky feeling, as with other grind guards. REMOLDABLE FOR A PERFECT FIT - Designed for a quick & easy custom fit for optimal performance. Can be remolded up to 20 times for a perfect fit!
