Abstract
Zinc oxide particles, preferably agglomerated, are added to dentifrices such as toothpastes, tooth gels, or tooth powders to inhibit the formation of plaque. The dentifrices contain sodium bicarbonate and other conventional ingredients such as thickeners, anti-calculus agents such as a pyrophosphate salts, anti-caries agents such as sodium fluoride, flavorings, sweetening agents, and/or secondary abrasives.
