Abstract: A whitening dentifrice composition includes a chemical whitening agent, where the chemical whitening agent comprises malonic acid or a salt thereof. The whitening dentifrice composition may be free of, essentially free of, or substantially free of polyphosphate. A method of whitening teeth includes applying the whitening dentifrice composition to the teeth and removing the whitening dentifrice composition from the teeth. The whitening dentifrice composition may provide efficacious oral hard tissue whitening benefits with fewer drawbacks that are observed with other whitening agents.

Abstract: A whitening dentifrice composition includes malonic acid or a salt thereof and a thickening system comprising xanthan gum, carrageenan, and about 1.5% or greater, by weight of the composition, of thickening silica. The whitening dentifrice composition has a pellicle cleaning ratio (PCR) value of at least 115.

Abstract: Kits comprising unit-dose oral care compositions with two or more flavors. Kits comprising unit-dose oral care compositions with two or more benefit agents. An oral care regimen comprising applying water to a toothbrush and picking up a unit-dose oral care composition without the consumer having to handle the unit-dose oral care composition.

Abstract: An applicator for the application of an oral care composition to an oral cavity. The applicator may include an applicator tip and an applicator handle detachably or non-detachably connected to a proximal end of the applicator tip. The applicator tip may include an external ridge, a plurality of internal ridges, and a plurality of internal channels between the plurality of internal ridges.

Abstract: A method of treating teeth includes applying an oral care article to at least one tooth, maintaining the oral care article on the at least one tooth for a first period of time, and, after the first period of time, directing a light radiation toward the at least one tooth for a second period of time, the first period of time having a duration greater than 50% of a total duration of the first period of time and the second period of time. The oral care article includes a solid water insoluble delivery carrier and solid hydrophilic particles embedded in the solid water insoluble delivery carrier partially below the first surface and partially at or above the first surface of the solid hydrophobic delivery carrier.

Abstract: Oral care compositions including dicarboxylic acid and a fluoride ion source. A pH of the oral care composition can be from about 4.5 to about 7. The oral care composition can provide an enhanced anticaries benefit, a stain prevention benefit, and/or a stain removal benefit. The oral care composition can be a dentifrice composition that results in a calcium loss in dentin and/or enamel of less than 50 ppm.

Abstract: An oral care composition includes a dicarboxylic acid or a salt thereof, a fluoride ion source, and silica abrasive. The composition may have a pH in a range of from about 4 to about 5.5. The oral care composition, after 12 months of aging at about 20° C., may have a soluble fluoride level that is more than 50% of a theoretical amount of fluoride.

Abstract: An oral care article in form of a strip for use in the oral cavity. The oral care article comprises a solid hydrophobic delivery carrier comprising solid hydrophilic particles comprising a bleaching agent, where the solid hydrophilic particles are embedded in the carrier. The concentration of the bleaching agent at a first surface of the solid delivery carrier is greater than the concentration of the bleaching agent at a second surface of the solid delivery carrier. The concentration of the bleaching agent at the first surface is from about 10 micrograms/cm2 to about 5000 micrograms/cm2.

Abstract: A method of treating teeth includes applying a multi-phase oral composition to at least one tooth, maintaining the multi-phase oral composition on the at least one tooth for a first period of time, and, after the first period of time, directing a light radiation toward the at least one tooth for a second period of time, the first period of time having a duration greater than 50% of a total duration of the first period of time and the second period of time. The multi-phase oral composition includes an aqueous phase having a bleaching agent and a semi-solid hydrophobic phase. The semi-solid hydrophobic phase includes petrolatum or microcrystalline wax.

Abstract: An oral care article for use in the oral cavity includes a water insoluble delivery carrier comprising solid hydrophilic particles comprising at least one bleaching agent. At least about 20 parts by weight of the solid hydrophilic particles dissolve in about 100 parts by weight of water, and/or the solid hydrophilic particles increase by volume and/or weight by at least about 50% in water. The particles are embedded in the carrier partially below the first surface and partially at or above the first surface of the solid hydrophobic delivery carrier. A concentration of the bleaching agent is from about 0.01% to about 15%, by weight of the article.

Abstract: Oral care light devices, kits, and methods are provided.
