FIELD: medicine, pharmaceutics.
SUBSTANCE: claimed invention relates to a teeth bleaching composition, which includes (i) in fact, a water-insoluble and in fact indestructible component of a polymer matrix, which is capable of tight connection with the tooth surface, on condition that, if the component of the polymer matrix is in unsteady form, it can be subjected to solidification by chemical modification, where the claimed component of the matrix represents a vinyl-containing polymer, obtained from, at least, two types of monomers, each of which contains an acrylate group; and (ii) filled with gas, which includes air, carbonic gas, nitrogen, argon or their mixture, or liquid, which includes water, alcohol (for example, ethanol) or their mixture, pores, included in the said component of the polymer matrix, in which, at least, part of the said filled with gas or liquid pores has, at least, one value of size in the range from approximately 100 nm to approximately 5 mcm, and filled with gas or liquid pores and the component of the polymer matrix have difference in coefficient of refraction, at least, equal to 0.1.
EFFECT: composition improvement.
