BRITE Teeth. Ten Days. The BRITEN Advanced Teeth Whitening Kit uses dual-light technology inside of a comfortable mouthpiece to unlock your most dazzling smile. With over 65+ whitening treatments included, our proprietary teeth whitening solution targets tough stains and whitens deeply and evenly, allowing you to experience a professional whitening procedure in the comfort of your own home.  Our kit does more than whiten teeth! A blue LED light in the mouthpiece accelerates the whitening process, while a red LED light reduces sensitivity and improves overall gum health. Use both lights together to combine the benefits of accelerated whitening and valuable gum support!
