ABSTRACT:
A foamable fluoride composition, for use in dental therapy, is provided that contains water, dental fluoride, foaming agent and acidifying agent. An illustrative composition comprises water, sodium fluoride, hydrofluoric acid, ethoxylated polyoxypropylene adduct of propylene glycol and phosphoric acid. The foamable fluoride composition, which is packaged in a nonmetallic, acid resistant, aerosol container in combination with an aerosol propellant, is dispensed into the trough of a dental tray as a dense, stable, non-flowable foam which is superimposed about and into engagement with the teeth to be treated to thereby effect fluoride uptake by the dental enamel. The fluoride foam provides substantially the same fluoride uptake as a fluoride gel but this result is achieved by the fluoride foam with substantially less fluoride in the tray than that which is present in a corresponding tray containing a like volume of fluoride gel.
