In-office teeth-whitening system. Takes up minimal space and is easily portable, this kit features patented G.L.O. (guided light optics) warming heat-and-light technology in a universally sized, autoclavable whitening mouthpiece that can be used with multiple patients (tested to exceed 30 autoclave cycles of 18 minutes each at 273°F). Short, 8-minute whitening applications means only 16 minutes of total whitening treatment time.
