<p>A mouth guard composition comprises 39 to 98 % by weight of styrene block copolymer; 1 to 60 % by weight of one or more kinds of thermoplastic resins selected from the group consisting of aliphatic cyclic saturated hydrocarbon resin, terpene resin, aliphatic petroleum resin and ester gum; and 0.1 to 40 % by weight of one or more kinds of waxes selected from the group consisting of mineral wax, synthetic wax, plant wax, and animal wax, said composition further comprising 0.1 to 20 % by weight of polyolefin resin, thereby providing the mouth guard composition which is not largely distorted when extremely strong impact force is applied thereto during the use of the mouth guard and can protect teeth and jaws, and little wearing is caused when repetitive force is applied.</p> |
