PROBLEM TO BE SOLVED: To provide a composition for mouth guards capable of preventing plastic deformation, having high flow properties at the time of forming after heating and softening for achieving excellent adaptability, and allowing to use the manufactured mouth guard repeatedly without generating stickiness on the surface and without bad smell. SOLUTION: The composition for the mouth guard composed of a styrene block copolymer of 39-98 wt.%; at least one thermoplastic resin of 1-60 wt.% selected from the group consisting of an alicyclic saturated hydrocarbon resin, a terpene resin, and an aliphatic petroleum resin; and at least one wax of 1-40 wt.% selected from the group consisting of a mineral wax, a synthetic wax, a vegetable wax, and an animal wax.
