A method for whitening teeth is provided where the method includes contacting at least one tooth surface with a semisolid oral dispersion. The semisolid oral dispersion may include solid hydrophilic active agent particles, where at least about 20 parts, by weight, of the solid hydrophilic active agent particles are soluble in about 100 parts, by weight, of water or the solid hydrophilic active agent particles swell by at least about 50% upon contact with water, and at least about 60%, by weight of the semisolid oral dispersion, of a semisolid hydrophobic phase.

Semisolid oral dispersions comprising active agents

Jammed oil-in-water emulsion toothpaste compositions. Opaque jammed oil-in-water emulsion toothpaste compositions without an opacifier and/or abrasive. Toothpaste compositions including jammed oil-in-water emulsion wherein the opacity can be modified through physical manipulation. Toothpaste compositions comprising jammed oil-in-water emulsion wherein the toothpaste composition is opaque without a solid opacifier.

Jammed emulsion toothpaste compositions

In a tooth whitening method, a whitening composition is applied to at least one tooth. The whitening composition is maintained on the at least one tooth for a first time period. After the first time period, a light radiation is directed toward the at least one tooth for a second time period. The first time period has a duration greater than 50% of a total duration of the first and second time periods.

Methods for whitening teeth

Semisolid oral dispersions for improving the health and/or appearance of the oral cavity. The semisolid oral dispersions include hydrophilic active agent particles in hydrophobic phase. The hydrophilic active agent particles can include bleaching agents, antimicrobial agents, anticalculus agents, and/or combinations thereof. The hydrophilic active agent particle can have a solubility in water of at least about 20 parts, by weight of the particles, in about 100 parts, by weight, of water. The hydrophobic phase can be semisolid petrolatum.

A kit includes a multi-phase oral composition for whitening teeth and a delivery carrier. The multi-phase oral composition for whitening teeth includes from about 0.002% to about 30%, by weight of the multi-phase oral composition, of a discontinuous aqueous phase having up to 10%, by weight of the multi-phase oral composition, of a bleaching agent and a continuous hydrophobic phase having at least about 50%, by weight of the multi-phase oral composition, of petrolatum.

Electromagnetic radiation and multi-phase oral compositions for oral care

A multi-phase oral composition for whitening teeth.

Multi-phase oral composition

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.

Device for applying emulsion compositions

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.

Kits comprising unit-dose oral care compositions

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/cmto about 5000 micrograms/cm.

Oral care article comprising a hydrophobic delivery carrier and solid hydrophilic particles comprising a bleaching agent

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.

Multi-phase oral composition for tooth whitening

An oral care article in form of a strip for use in the oral cavity. The oral care article includes a hydrophobic delivery carrier comprising embedded solid hydrophilic particles comprising at least one bleaching agent, wherein at least about 20 parts by weight of the particles dissolve in about 100 parts by weight of water and/or the particles increase in volume and/or weight by at least about 50% upon contact with water.

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 an active agent for oral care. The active agent(s) for oral care can include an anti-calculus agent, an anti-caries agent, an antimicrobial agent, a dentinal desensitizing agent, a bleaching agent, or combinations thereof. The concentration of the active agent for oral care at a first surface of the solid hydrophobic delivery carrier is greater than the concentration of the active agent at a second surface of the solid hydrophobic delivery carrier.
