An oral tray for conditioning teeth within a mouth of a user includes a first tray layer and a second tray layer. The first tray layer is configured to engage teeth within the mouth of the user. The first tray layer can have a first Young's modulus of greater than 0.60 and less than 1.50. The first tray layer can have a first tray thickness of greater than 0.40 mm and less than 0.90 mm. The second tray layer is coupled to the first tray layer. The second tray layer has a plurality of tooth portions each including a recess. Each recess is configured to receive a tooth conditioner. The second tray layer can have a second Young's modulus of greater than 0.02 and less than 0.30. The second tray layer can have a second tray thickness of greater than 0.80 mm and less than 1.30 mm.

An oral treatment device that emits light onto surfaces of a user's teeth. In one aspect, the oral treatment device includes an intraoral mouthpiece. The mouthpiece comprises a lamp support structure comprising a lamp support surface and is formed of a first material. A flexible lamp is mounted to the lamp support surface so that a light emitting surface of the flexible lamp assumes a concave curvature, thereby forming a lamp assembly. A guard component is overmolded to the lamp assembly. In one embodiment, the oral treatment device may be a teeth whitening device.

Silver-fluoride compositions, dental articles comprising silver-fluoride compositions, and methods for reducing bacteria on a tooth surface and/or remineralizing a tooth surface are described.

A curable composite material containing nanodiamonds, denture bases and other dental prosthetics made from the composite material and methods for treating dental stomatitis using these prosthetics.

A system includes a dental appliance having a polymeric shell with a plurality of cavities for receiving one or more teeth; and a biocompatible cosmetic aqueous liquid in the cavities of the polymeric shell of the dental appliance. The aqueous liquid includes a viscosity modifier chosen from a water compatible polymer, a polysaccharide, a silica compound, and mixtures and combinations thereof, a tooth re-mineralizing agent, and water. The aqueous liquid is substantially free of tooth whitening agents and fluoride, and has a refractive index of greater than 1.3 at room temperature.

An oral treatment device and a method of using the same. The oral treatment device includes an intraoral mouthpiece configured for placement into a mouth of a user, which includes a lamp having a top edge and a bottom edge, a plurality of first electromagnetic radiation emitting elements that emit light in a first wavelength when activated, and a plurality of second electromagnetic radiation emitting elements that emit light in a second wavelength when activated. The first electromagnetic radiation emitting elements are positioned along the lamp to emit light onto the user's teeth and the second electromagnetic radiation emitting elements are positioned along the lamp to emit light onto the user's teeth.

A method includes placing a double barrel syringe into a dispensing gun. The method also includes using the dispensing gun to place a composition of paste A and paste B within the double barrel syringe through a mixing tip onto a tooth surface and interproximal areas along a gumline and/or subgingival areas. The composition softens and aids in removal of dental calculus, tarter, and/or plaque on one or more areas of the tooth surface that require cleaning. The method also includes rinsing the one or more areas of the tooth surface to enable the cleaning to begin.

The present invention provides for devices and methods of treating wounds, including general wounds, gum disease and gingival tissues post scaling/root planning, using a diode laser which generates a beam of light having a wavelength in the visible portion of the electromagnetic spectrum (400 nm-700 nm). Further disclosed are devices and methods capable of stimulating tissue regeneration at the site of a wound.

A teeth cleaning travel kit includes toothbrushing mouthpiece that has two inverted channels dimensioned to receive upper and lower bites of dental arches of a user, the channels being integral with one another. Teeth-cleaning bristles inwardly project within the two inverted channels to bear inwardly against teeth and gums of the user, wherein the channels and teeth-cleaning bristles are configured such that mastication produces relative brushing movement of the teeth-cleaning bristles over the teeth and gums. An oral hygiene promoting product is attached to one of the two inverted channels and the teeth-cleaning bristles that is released by action of the user's mouth. The teeth cleaning travel kit also includes a vessel that contains a rinsing fluid and kit packaging that contains the toothbrushing mouthpiece and vessel.

A shell-shaped dental appliance includes: a body which is an integral shell and forms a cavity for receiving teeth; and an anti-caries film which has a certain thickness, and is formed on at least a partial area of an inner surface of the body, and is able to react with saliva to release fluoride ions.
