Available exclusively from Hammacher Schlemmer, this is the only device that stimulates circulation inside your mouth to help maintain healthy gums. Using technology developed by NASA, the mouthpiece employs eight infrared (880nm) and eight red (660nm) LEDs that produce safe infrared heat that penetrates deep into gingiva tissue, boosting circulation to help promote oral health. Lightweight, portable, and simple to use, the cordless mouthpiece offers convenient one-button operation for the recommended 10-minute treatment. For those who use light-reactive whitening gel to brighten their teeth, the mouthpiece also has 12 blue LEDs that allow you to simultaneously get a whitening treatment as you treat your gums (gel not included). Internal battery recharges in 4-6 hours via AC adapter. Includes a hard plastic travel case. 4 1/2" L x 2 1/4" W x 1" H. (3 oz.)
