A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation. Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and/or disclosing undesired substances, and/or foaming. The dentifrice may be clear and may have clear abrasive particles. A method for tuning the cleaning and whitening system for teeth includes formulating the dentifrice with photosensitive agents that react to a range of electromagnetic radiation and providing a toothbrush that emits that electromagnetic radiation range. Another method of tuning the cleaning and whitening system includes designing a toothbrush that emits a range of electromagnetic radiation and formulating a dentifrice with photosensitive agents that react to the electromagnetic radiation range.

An instructional hygiene method includes providing an instructional hygiene device, the instructional hygiene device configured to provide an instruction to a user during operation, and delivering said instruction from said instructional hygiene device to said user in response to activation of a user input of said instructional hygiene device. The instructional hygiene device can include a toothbrush or a dentifrice dispenser. The delivering an instruction step can include instructing the user regarding a tooth-brushing technique, instructing the user to move a toothbrush head in a circular motion, instructing the user to brush a tongue, and/or providing music to the user. In addition, the step of delivering the instruction can include retrieving the instruction from a memory of the instructional hygiene device.

A dentifrice composition having a low water phase comprising effective amounts of polyphosphate and ionic active ingredients.

Disclosed are oral care compositions, particularly thickened dentifrices in liquid, paste or gel form comprising a binding/thickening system that also function effectively as humectant agent thereby replacing a significant portion or all of traditional humectant components such as glycerin, sorbitol and other polyols. The binding/thickening system comprise select carrageenans that provide a water viscosity of at least about 20 mPa·s in a 1.5% solution at 25° C. and effective water-binding capacity to prevent significant water loss from the composition when exposed to air to cause unacceptable drying out. For example, the water-binding capacity of the carrageenan must be effective such that there is no more than about 0.75% water loss from a dentifrice composition when exposed to air for 30 minutes at room temperature conditions and 50% relative humidity. The present dentifrice compositions exhibit increased dispersibility in saliva during use, which provides for increased contact time of the composition with the user's teeth and oral cavity tissues such that the active dental agents contained therein are more rapidly available to effect their beneficial activity.

A method of making precipitated silica abrasive compositions having excellent cleaning performance and lower abrasiveness with post-reactor sizing of the abrasive particles being performed via air classification techniques is provided. By targeting a specific particle size range, it has been determined that higher pellicle film cleaning levels may be achieved without also increasing the dentin abrasion properties of the silica products themselves. As a result, dentifrices including such classified abrasive silica products, and exhibiting particularly desirable cleaning benefits, can be provided for improved tooth polishing, whitening, and the like, without deleteriously affecting the hard tooth surfaces. Also encompassed within this invention also are products of this selective process scheme and dentifrices containing such classified silica products.

The present invention is directed to dental compositions, including dentifrices, containing ascorbic acid for removing and inhibiting dental biofilms which form plaque and tartar, and also for treating and preventing gingivitis and periodontitis. The ascorbic acid composition can contain may additional ingredients, including an enamel-strengthening component, and be used in many different forms, including breath spray, chewing gum, dental floss, dental powder, gargle, lozenge, mouth spray, mouth wash, tooth gel, tooth liquid, tooth paste and tooth strips. Also described in a method of using a dental composition containing ascorbic acid in order to treat plaque and tartar as well as gum disorders.

The invention provides a single phase whitening dentifrice that includes (i) a whitening agent selected from the group consisting of hydrogen peroxide, a bound peroxide and a solid peroxide (ii) an abrasive and (iii) a substantially anhydrous orally acceptable carrier, for example, polyethylene glycol. The bound peroxide may be hydrogen peroxide and a polymer and/or any peroxide compound and a porous cross-linked polymer, such as polymers of polyvinyl pyrrolidone, polyacrylates, a polymethacrylates, and a polyitaconates. The solid peroxide may be sodium perborate or urea peroxide. The invention also provides methods of whitening the tooth surfaces by contacting the surface with the composition.

Oral compositions are provided that comprise a propolis extract; an oral care active compound chosen from: a cationic antibacterial agent, an anti-attachment agent, a biofilm disruption agent, and an anti-inflammatory agent; and a source of fluoride ions. Further, in certain embodiments, the oral composition comprises an anionic polymeric linear polycarboxylate. The oral composition can be in a form of a mouth rinse, a dentifrice, a confectionary, a medicament, or a film. Methods of making and using the oral compositions are also provided.

An efficacious antibacterial and anti-inflammatory oral composition is provided having an active ingredient combination comprising one or more active compounds from an extract of magnolia and an extract of hops. Preferably, the active compounds from magnolia extract comprise honokiol and magnolol, and the active compounds from hops extract comprise hexahydrogenated beta acids. The oral composition can be in the form of a mouth rinse or dentifrice, including toothpaste, gels, powders, confectionaries, lozenges, animal products, and the like. Methods of making and using the oral composition are also provided.

A method of making abrasive compositions, and more particularly, it relates to a method of making precipitated silica abrasive compositions having excellent cleaning performance and lower abrasiveness with post-reactor sizing of the abrasive particles being performed directly via wet comminution and centrifugation, optionally followed by hydraulic chamber press filtering combined with vacuum dewatering and de-agglomeration is provided. By targeting a specific particle size range, it has been determined that higher pellicle film cleaning levels may be achieved without also increasing the dentin abrasion properties of the silica products themselves. As a result, dentifrices including such classified abrasive silica products, exhibiting particularly desirable cleaning benefits, can be provided for improved tooth polishing, whitening, and the like, without deleteriously affecting the hard tooth surfaces. Also encompassed within this invention also are products of this selective process scheme and dentifrices containing such particularly manufactured and classified silica products.
