Dye compositions and methods for whitening teeth using same
InactiveUS6030222AEliminate the problemWhiter teethCosmetic preparationsGum massageNatural toothToothpaste
Compositions, methods and systems for whitening teeth. A whitening composition is applied to off-white or yellowish teeth in order to hide or mask the inherent underlying natural tooth color to yield whiter looking teeth. The whitening composition includes a complementary dye that, when absorbed by a tooth, will cause the tooth to reflect a color of light that is whiter than the natural or initial color reflected by the tooth. The tooth whitening composition may comprise a toothpaste that is applied like any conventional toothpaste in order to achieve whitening without significant alteration of a person's daily routine. Alternatively, the tooth whitening composition may be adapted for direct application onto the teeth in a more concentrated form, such as by means of a syringe, tooth cleaning paste, or cotton swab. The tooth whitening compositions can be used instead of, or in addition to, dental bleaching compositions in order to achieve whiter teeth while reducing or eliminating tooth sensitivity caused by some bleaching regimens. The inventive whitening compositions may also be used in conjunction with a bleaching composition in order to maintain whiter teeth for a larger period of time before undertaking subsequent bleaching regimens.

InactiveUS6503485B1Maintain bleaching potencyHigh concentrationCosmetic preparationsGum massageParticulatesAlkaline earth metal
Dental bleaching systems that include a bleaching component and a neutralizing component which, when mixed together, yield a mixed composition having a desired bleaching activity and viscosity. The bleaching composition includes a suitable bleaching agent, such as aqueous hydrogen peroxide, in a concentration of about 3% to about 95% by weight of the bleaching composition component. The neutralizing component includes a particulate base dispersed within a stable gel that includes at least one polymeric thickening agent. The neutralizing component is substantially water-free to prevent destruction of the gelling capability of the thickening agent by the base. The particulate base may include oxides, hydroxides or carbonates of alkali metals or alkaline earth metals. Maintaining the bleaching agent and neutralizing agent in separate components provides increased stability during storage and transport.

Dental bleaching compositions in the shape of a dental tray, strip or patch include an adhesive activation composition and a dental bleaching gel. A barrier layer may be included to form a dental bleaching device that protects the bleaching composition from saliva or moisture during use. The adhesive activation composition is substantially solid and has increased adhesiveness to oral tissue when moistened with saliva or water. The adhesive activation composition is formed from an intermediate composition that is heated to drive off the solvent. Using a bleaching gel separate from the adhesive activation composition improves the potency and stability of the bleaching agent prior to use. During use, saliva or moisture cause the bleaching gel to be activated as the bleaching agent activator in the activation composition is leached therefrom so as to react with and destabilize the bleaching agent within the bleaching gel.
