Abstract: There is herein described a dental kit comprising a dental aligner or mouth tray and dissolvable films. More particularly, there is described a dental kit comprising a dental aligner or mouth tray and dissolvable films wherein the dental aligner acts to straighten teeth and the dissolvable film may 5 contain active ingredients that may promote whitening and/or reduction of dental hypersensitivity (DH) in teeth.

Abstract: There is herein described a teeth whitening strip or film. In particular, the present invention relates to a dissolvable or substantially dissolvable hydrogen peroxide (H2O2) teeth whitening strip or film comprising a concentration of hydrogen peroxide (H2O2) at or above 10 wt. % of the strip or film. There is also described a process for the manufacture of a dissolvable or substantially dissolvable tooth whitening strip or film along with the method of using a strip or film comprising a concentration of hydrogen peroxide (H2O2) at or above 10 wt. % of the strip or film to whiten and/or bleach teeth.

Abstract: A tooth whitening and/or tooth sensitivity strip or film comprising: about 1-20 wt. % hydroxyapatite (HAP). A process for the manufacture of a tooth whitening strip or film, the process comprising at least the steps of: —mixing at least one or a combination of polyvinylpyrrolidone (PVP) polymers wherein the amount of the polyvinylpyrrolidone (PVP) polymers is greater than 75 wt. % of the film or strip; and —an amount at least about 1-20 wt. % hydroxyapatite (HAP); and —at least one or a combination of polycarbophils; —with water to provide an aqueous tooth whitening liquid; —applying the aqueous tooth whitening liquid to a substrate to provide a substrate carrying the aqueous tooth whitening liquid; —drying the aqueous tooth whitening liquid to provide a tooth whitening film on the substrate, said film having a thickness from about 50 pm to about 500 pm.

Abstract: The present invention provides a tooth whitening film. The tooth whitening film comprises a dental bleaching agent comprising one or both of a non-hydrogen peroxide bleaching agent and hydrogen peroxide in a hydrogen peroxide-polymer complex, one or more polyphosphates, said one or more polyphosphates comprising one or more cyclic polyphosphates, one or more water soluble film-forming polymers, one or more plasticizers and one or more emulsifiers, wherein the film has a thickness from about 50 ?m to about 500 ?m. A kit comprising one or more such films having a thickness from about 50 ?m to about 150 ?m and a dental aligner is also provided. A process for the manufacture of the film is also provided, together with a method of using such a film to bleach teeth.

Abstract: The present invention provides oral compositions. The compositions may be provided in a solid form, such as a film. The compositions can comprise one or more film forming polymers, one or more bioadhesive agents, one or more active agents, one or more polymeric solvents, and an aqueous solvent, with the proviso that the composition does not comprise benzocaine. The active agent(s) preferably are effective for a range of effects. The oral composition can be a solid or semi-solid composition up to a temperature of at least 40° C. Methods of providing such an oral compositions and methods of applying them to an oral or buccal cavity are also provided herein.
