Oral compositions containing fluoride, pyrophosphate, peroxide, and nonionic and/or amphoteric surfactants

The oral composition comprising a soluble fluoride source capable of providing from about 50 ppm to about 3500 ppm of free fluoride ions;

• an amount of at least about 1.5% tetrasodium pyrophosphate;
• from about 0.01% to about 5% of a peroxide source;
• from about 0.25% to about 5% of each surfactant selected from the group consisting of nonionic surfactants, amphoteric surfactants, and combinations thereof;
• and from about 78% to about 98% of one or more aqueous carriers;
• wherein the oral composition has a neat pH of from about 9.0 to about 10.5 and a total water content of from about 5% to about 20%, produced according to a process comprising the steps of:
• a. preparing a mixture of a soluble fluoride source and one or more aqueous carrier materials including a surfactant selected from the group consisting of nonionic surfactants, amphoteric surfactants, and combinations thereof;
• b. adding tetrasodium pyrophosphate and calcium peroxide, all at once or in portions, under conditions wherein less than about 20% of the total pyrophosphate and calcium peroxide are dissolved in the dentifrice mixture, and wherein any further remaining aqueous carrier materials not added to the mixtures during step (a) are added in whole or in part in step (b) or thereafter, either by themselves or with any remaining amount of the tetrasodium pyrophosphate or calcium peroxide under conditions such that less than about 20% of the total pyrophosphate and calcium peroxide are dissolved in the mixture;
• and
• c. heating the mixture to a temperature range of from about 38.degree. C. to about 71.degree. C.
