• What makes the indigo LED light work?

    We’re glad you asked! Our clinically proven & patented LED uses indigo light - a higher energy light that amplifies the power of the pen’s serum even further. These tiny, powerful lights make tooth stains more receptive to the bleaching power of hydrogen peroxide, and are effective against a broad spectrum of stains. The shape of the device covers both top and bottom row of teeth, for complete coverage.

  • How white will my teeth get?

    While everyone’s results vary, if properly used for 10 minutes a day for 10 days, your teeth should be six shades whiter, comparable to what you’d receive from a professional whitening treatment in a dentist’s office. That’s a big enough difference to take before-and-after photos!

  • Will the teeth whitening treatment cause tooth sensitivity?

    Every individual varies in how they respond to teeth whitening. This kit has been designed for no teeth sensitivity using a lower grade of hydrogen peroxide. However, some people may experience tooth sensitivity or gum discomfort when using whitening products. This discomfort is temporary and not harmful. If you experience more than mild tooth sensitivity or gum discomfort, stop use and consult your dentist.

  • Is the teeth whitening device safe for use? Will it damage my teeth?

    At Colgate, we take the safety of your dental care seriously. Our Teeth Whitening Device has been rigorously tested and is 100% safe for consumer use. It won’t harm your tooth enamel or gums.
