Grillz are reusable.
Material:
Grillz are lead and nickel free & FDA approved. The Base metal is brass, rhodium finish.
Fitting Instructions:
Custom fitting our grillz at home is easy only takes 5 minutes! Just put the grill and silicone molding in hot water to soften the mold. Then put the grill with the molding bar in your mouth and bite down. Once the mold hardens, adjust the back prongs on the grill for a tight fit. Then you’re all set! To readjust, just put the molding bar in hot water again and fit again.
