Abstract

Semisolid oral dispersions for improving the health and/or appearance of the oral cavity. The semisolid oral dispersions include hydrophilic active agent particles in hydrophobic phase. The hydrophilic active agent particles can include bleaching agents, antimicrobial agents, anticalculus agents, and/or combinations thereof. The hydrophilic active agent particle can have a solubility in water of at least about 20 parts, by weight of the particles, in about 100 parts, by weight, of water.
