Abstract
Zinc oxide particles, preferably agglomerated, are added to dentifrices such as toothpastes, gels, or tooth powders. The dentifrices may contain other conventional ingredients such as thickeners, flow aids, flavoring and/or sweetening agents, anti-calculus agents such as a pyrophosphate salt, and/or an anti-caries agent such as sodium fluoride.
