ABSTRACT:
Previous mouthwashes and dentifrices containing fluoride contributed relatively modest amounts of additional fluoride to the tooth surfaces, and scavenged calcium from the teeth. The present invention can deposit significantly more fluoride in the mouth than previously used formulations containing comparable amounts of fluoride, without scavenging calcium from the teeth. The invention includes a method of fluoridating teeth comprising (1) mixing in an aqueous environment a first component comprising a stable, non-toxic soluble calcium salt with a second component comprising a stable, non-toxic readily hydrolyzable complex fluoride compound, resulting in hydrolysis of the fluoride compound and precipitation of calcium fluoride, followed by (2) prompt application of the mixture to tooth surfaces. The invention also contemplates mouth rinses, denifrices, gels or pastes, and chewable tablets for application of the above-described compositions.
