Abstract
A composite bleaching tray has a U-shaped base composed of a nonsoftening, resilient, low compression elastomer. The U-shaped base has an upward outer labial wall. A flexible and tough, softenable thermoplastic sealing portion is molded to the top of the outer labial wall and forms an inner lingual wall. A handle is attached to the U-shaped base for immersing the tray in boiling water for softening the thermoplastic sealing portion. The handle is removable after the bleaching tray is fitted to the mouth. The bleaching tray also includes a sizing kit for selection of the correctly sized small to large bleaching tray for the user.
