FIELD: medicine, pharmaceutics.

SUBSTANCE: group of inventions concerns an oral care composition and methods of using it. The oral care composition contains a zinc oxide particle source, wherein the above zinc oxide particles have a median particle size of 1 to 7 mcm; one or more amino acids able to chelate with the above zinc oxide particles, and an orally acceptable vehicle. The composition can additionally contain a polymer binding material for binding metal oxide particles in a dentinal canal. Presented are methods using the above composition, namely: a method for reducing dental sensitivity, a method for protecting against dental decay caused by an acid, a method for blocking the dentinal canals on the mammalian dental surface, and a method for preserving or improving the mammalian general state.

EFFECT: using the group of inventions provides the improved zinc oxide delivery to the dental surface that is expected to improve antibacterial properties of the composition alongside with the effective blocking of the dentinal canals.
