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.
