Toothpaste and other dentifrices formulated to include a volume increasing agent (density reducing agent) in order to significantly increase the volume of the toothpaste at the time it is dispensed onto a toothbrush. The inventive dental compositions preferably include a substantial quantity of entrained or trapped air or other gas in order to reduce the density, and hence the weight, of toothpaste actually placed within a person's mouth. The result is a reduction in the amount of active ingredients introduced into a person's mouth that might be ingested. The entrained air or other gas can also increase the availability of the active ingredient since the foamed composition increases the dispersibility of the active ingredients within saliva. The net effect is that a person decreases the actual amount of toothpaste without decreasing the volume, or visual amount, of toothpaste dispensed on the toothbrush. The density-reduction effect can alternatively be provided by means of a lower density filler in addition to, or instead of, the entrained gas. Such fillers typically include trapped air or voids.

[ What is claimed and desired to be secured by United States Letters Patent is:] [1.] A dental composition for delivering a reduced quantity of fluoride ions into a person's mouth comprising:a base composition including a fluoride ion source that provides from about 10 ppm to about 3500 ppm of fluoride ions, an abrasive solid, and a carrier selected from the group consisting of liquids, gels, pastes, and mixtures thereof, the base composition having a density; anda density reducing component dispersed throughout the base composition and included in an amount so as to yield a final dental composition having a density that is at least about 30% less than the density of the base composition in order to thereby reduce the quantity of fluoride ions delivered per unit volume of the dental composition by at least about 30% relative to the base composition, wherein at least a portion of the density reducing component comprises a lower density solid filler,wherein the dental composition has a rheology such that it can be expressed onto a toothbrush as a coherent mass and a sufficiently low level of abrasiveness such that it is suitable for use in daily tooth brushing.
