Abstract: An apparatus for whitening teeth comprises a mouth tray comprising a horseshoe-shaped trough sized to accommodate a dental ridge. A planar projection extends from the outer side of the trough so that its far end is external of the mouth. A light box containing a plurality of LEDs couples with the external end of the projection and illuminates the projection end. The mouth tray and projection are formed of a light-transmissive material to irradiate a peroxide gel in the trough to whiten the user's teeth.
