[0077]In one embodiment of an inventive apparatus, shown in FIG. 5, a support structure having a generally described U-shape is shown at 200. A textured surface 202 is shown including hexagonal cells 204. The cells 204 act as reservoirs for delivery of whitening compositions and here are shown containing beads 206 which enclose a whitening composition, such as hydrogen peroxide in a concentration ranging from 3-35%. A phosphorescent light source (not shown) is integral to the support shown, such that when an exciting light is directed at the support for a period of time, the support glows for a period after the exciting light is removed.

[0078]Although the invention is described as appropriate for delivering a dental whitening composition and for use in a method for whitening teeth, it is appreciated that a support structure as described herein may be used to deliver other treatments via an oral route. For example, therapeutic agents to treat dental or systemic diseases or conditions...

Abstract

A method and apparatus for whitening teeth which allow the user to undergo dental bleaching with the mouth closed and without protruding instruments, trays or electrical wires and the like. The apparatus includes a support structure and a dental whitening composition in contact with the support structure. A light source is included in the apparatus, disposed on or in the support structure so that light emitted from the source contacts on the dental whitening composition. The apparatus has a volume ranging between 0.5-450 cm3 permitting the apparatus to fit entirely within the mouth of a user during treatment.
