Abstract:
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.
