Patent ID: 8545819

Claim:
A toothpowder composition comprising a clinically efficacious fluoride ion source particulate selected from sodium monofluorophosphate sodium fluoride, stannous fluoride, and combinations thereof, and an orally acceptable calcium carbonate abrasive particulate wherein in a bed of the toothpowder of a volume of at least 125 cubic millimeters at least 99 percent of individual calcium carbonate particles in said bed have an independent calcium carbonate particle size from about 10 to about 150 microns, at least 99 percent of individual fluoride ion source particulate particles in said set have an independent fluoride ion source particulate particle size from about 10 to about 150 microns, and any 125 cubic millimeter volumetric portion of said bed has a concentration of fluoride ion source providing from about 500 to about 1500 parts per million of soluble fluoride respective to calcium carbonate.
