A device is provided for the treatment of teeth including an outer layer of non-porous polymeric material forming a trough, an inner layer forming an inner lining of the trough, and a treatment layer including a treatment agent disposed between the outer layer and the inner layer. The inner layer allows penetration of the treatment agent through after an aqueous solution is introduced to the device. A device is provided for the treatment of teeth including an outer layer of non-porous polymeric material in the form of a trough, wherein the trough has an outside and an inside surface. An outer lining layer is proximate to the inside surface of the outer layer; the outer lining layer includes a material for retaining a treatment agent. An inner lining layer forms an inner lining of the trough, wherein the inner lining layer includes a water-permeable material. A treatment layer is disposed between the inner lining layer and the outer lining layer, wherein the treatment layer includes a treatment agent. A method is provided for bleaching teeth or dentures of a subject. The method includes providing a laminated device having a trough for the treatment of the teeth of the subject, wherein the device includes an outer layer of non-porous polymeric material in the form of a trough, an inner layer forming an inner lining of the trough, and a treatment layer including a treatment agent disposed between the outer layer and the inner layer. An aqueous solution is added to the laminated device, and the teeth or dentures of the subject in are placed in the device. A method of treating a tooth is provided, including capturing a treatment agent between a liner and a trough; and introducing an aqueous solution, thereby inducing the penetration of said treatment agent through said liner to treat the tooth. A composition is provided for the whitening of a tooth including a dry form of a gel forming agent and a bleaching agent. A laminated device is provided that has a trough for the treatment of the teeth of a subject, wherein the device includes a first layer of non-porous polymeric material in the form of a trough and a premeasured amount of a composition for whitening of a tooth including a dry form of a gel forming agent and a bleaching agent.

[ What is claimed is:] [1.]1. A device for the treatment of teeth, comprising:an outer layer of non-porous polymeric material forming a trough;an inner layer forming an inner lining of said trough; anda treatment layer comprising a treatment agent encased between said outer layer and said inner layer,wherein said inner layer allows penetration of said treatment agent through said inner layer after an aqueous solution is introduced to said device and wherein said inner layer does not allow a substantial portion of said treatment agent to pass through said inner layer before said aqueous solution is introduced, wherein said treatment agent is a bleaching agent, and said treatment agent is in dry solid powder form thereby avoiding a leakage problem of dental trays filled with gel or liquid treatment agents.
