Abstract
A method for whitening teeth is provided where the method includes contacting at least one tooth surface with a semisolid oral dispersion. The semisolid oral dispersion may include solid hydrophilic active agent particles, where at least about 20 parts, by weight, of the solid hydrophilic active agent particles are soluble in about 100 parts, by weight, of water or the solid hydrophilic active agent particles swell by at least about 50% upon contact with water, and at least about 60%, by weight of the semisolid oral dispersion, of a semisolid hydrophobic phase.
