A laminated mouth guard may include a shape memory layer, one or more of a cushion layer and a puncture resistant layer, and an adhesive layer. The adhesive layer may be gelatinous and may include a polymer. For example, the adhesive layer may include one or more of PVP, polyethyloxazoline, carboxypolymethylene, guar gum, and a hydrogel. In addition to the adhesive layer, the laminated mouth guard may include a sheet material comprising at least one of LDPE, HDPE, LDPP, HDPP, polyurethane, PVA, cotton, silicone rubber and non-woven PE.
