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 SnF , 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.

Dentin desensitizer containing stannous fluoride

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.

Dental composition for treating hypersensitive teeth

The present invention is a method for desensitizing and thereby relieving the pain and discomfort that often accompanies sensitive teeth in humans. A desensitizing agent in the form of a toothpaste, gel or mouthwash is applied to the surface of the teeth and physically forced into the dentinal tubules responsible for the sensitive condition using a flexible rubber or plastic applicator in the form of a cylindrical or rectangular post or block, preferably with an upper surface in the form of a recessed indentation, serrated surface or concave-shaped cup.

Applicator tip for desensitizing agents and method

Phosphate-free oral compositions containing cationically charged colloids are effective to treat tooth hypersensitivity.

Relief of dentinal hypersensitivity by submicron particles

A composition containing a water soluble or water swellable polyelectrolyte mixed salt in a dentifrice base or other oral compositions which can be used for relieving pain and discomfort caused by hypersensitive teeth.

Dentinal desensitizing compositions

A method for treating hypersensitive teeth by treating the teeth with an oral composition comprising hectorite clay, especially Laponite clay.
