FIELD: cosmetology.

SUBSTANCE: oral care composition comprising a mixture of a tetrabasic zinc halide and trimethylglycine (TMG) hydrochloride is proposed. A tetrabasic zinc halide-trimethylglycine hydrochloride complex is also proposed, as well as tetrabasic zinc halide application together with trimethylglycine hydrochloride in oral care product manufacture. Methods for composition application comprising application of the above composition to teeth are: a method for tooth enamel erosion treatment or reduction, a method for teeth cleaning, a method for reduction of s biofilm formed by bacteria, a method for plaque treatment or reduction, a method for gingiva inflammation treatment or reduction, a method for caries inhibition, a method for cavity formation treatment or reduction and/or dentin sensitivity reduction.
