Abstract
An acidified and foamable fluoride gel composition, for use in dental therapy, is provided that contains water, dental fluoride, foaming agent, gelling agent and acidifying agent. An illustrative composition comprises water, sodium fluoride, Pluronic F108 nonionic surfactant and phosphoric acid. The foamable fluoride gel composition, which is packaged in a suitable container, is dispensed onto a toothbrush, or the like, for application to the teeth to be treated to thereby effect fluoride uptake by the dental enamel. The foamable fluoride gel provides substantially the same fluoride uptake as a tray fluoride gel but this result is achieved by a foamable fluoride gel with substantially less fluoride than that which is present in a tray fluoride.
