A dental cream composition containing a binary fluorine providing system which provides about 1000-1670 ppm (0.1-0.16% by weight) fluorine from sodium monofluorophosphate and sodium fluoride wherein sodium fluoride provides about 30-35% by weight of the fluorine in amount of about 300-580 ppm (0.02-0.058% by weight). The dental cream contains a vehicle for the binary fluorine-providing system and about 20-75% by weight of a dentally acceptable water-insoluble polishing agent consisting essentially of dicalcium phosphate intimately dispersed in the vehicle and in direct contact with the binary fluorine-providing system. The dental cream is effective in retaining soluble fluorine and soluble fluoride, in effecting reduction of enamel solubility and in remineralization of dental enamel.
A dental cream composition comprising a dental vehicle, a binary fluorine providing system which provides about 0.1-0.167% by weight fluorine from sodium monofluorophosphate and sodium fluoride wherein said sodium fluoride provides about 30-35% by weight of the fluorine in amount of about 0.03-0.058% by weight and intimately dispersed in said vehicle, and in direct contact with said binary fluorine-providing system components about 20-75% by weight of a dentally acceptable water-insoluble polishing material consisting essentially of dicalcium phosphate.
A process for promoting oral hygiene including remineralizing demineralized dental enamel comprising applying to dental enamel a dental cream composition comprising a dental vehicle, a binary fluorine providing system which provides about 0.1-0.167% fluorine from sodium monofluorophosphate and sodium fluoride wherein said sodium fluoride provides about 30-35% by weight of the fluorine in amount of about 0.03-0.058% and intimately dispersing in said vehicle for contact with said binary fluorine-providing system components, about 20-75% by weight of a dentally acceptable water-insoluble polishing material consisting essentially of dicalcium phosphate.
