  • Patent number: 6592853
    Abstract: A desensitizing agent for the cleaning and treatment of sensitive teeth in which the essential desensitizing ingredient is a combination of a first desensitizing agent in an amount of about 0.1 to about 2 wt. % of SnF2, and a second desensitizing agent in an amount of about 0.1 to about 20 wt. % of a water soluble or water swellable polyelectrolyte. Dentifrice compositions employing the desensitizing agent of the present invention surprisingly exhibit excellent organoleptic and flavor release properties.
    Type: Grant

  • Patent number: 6416745
    Abstract: The present invention provides dental compositions and methods for treating dentinal hypersensitivity teeth based on the discovery that anionic liposomes possess the capacity to induce mineral formation in the dentinal tubules which partially or fully block them. The subject compositions comprise the liposomes and a suitable carrier and are advantageous in that they can deliver additional agents useful in the treatment of dentinal hypersensitivity, particularly nerve desensitizing agents, to the tubules. The liposomes of the invention are further advantageous in that they are stable to conventional sources of fluoride ion conventionally used as anti-caries agents. The methods of the present invention utilize the subject composition to effect blocking of the dentinal tubules and to simultaneously deliver other treatment agents such as nerve desensitizing agents for the combined benefits thereof.

  • Publication number: 20020037258
    Abstract: A dental product composition for the treatment of sensitive teeth contains an amorphous bioactive particulate material consisting essentially of calcium, silicon and oxygen in an amount sufficient to alleviate tooth sensitivity by causing the formation of calcium containing mineral within the dentinal tubules of sensitive teeth.
