FIELD: hygiene.

SUBSTANCE: group of inventions relates to a dental lacquer composition for preventing hypersensitivity of teeth, a method of using such a composition, as well as the use of ethyl cellulose for the dental lacquer manufacturing. Dental lacquer composition contains a source of fluoride; ethyl cellulose in an amount effective to provide suspension of the source of fluoride; vegetable resin, selected from mastic, rosin and combinations thereof; and a non-aqueous solvent; wherein: i) the fluoride source presents in an amount that is equal to or greater than the amount of ethyl cellulose; and ii) the dental lacquer composition contains neither shellac nor shellac wax. It is also suggested the use of ethyl cellulose in the manufacture of said dental lacquer and a method for preventing dental hypersensitivity or treating a symptom of dental hypersensitivity, comprising applying the mentioned lacquer composition to the teeth or gums of an animal.

EFFECT: use of synthetic ethyl cellulose instead of natural suspending components (shellac, shellac wax) provides a viscosity, suitable for suspending sodium fluoride in the formulation and does not lead to unacceptable phase separation.
