How does teeth whitening work?
Teeth-whitening gels use the key ingredient hydrogen peroxide, and it's the same for the AutoBrush Whitening Gel Pens. When exposed to the blue LED light from your AutoBrush, hydrogen peroxide gets activated and quickly breaks apart the top yellow layers on teeth.
Do whitening products cause sensitivity?
Our whitening products are safe to use and carefully formulated to not cause sensitivity. Factors contribute to sensitivity such as brushing too hard, gum recession and dental procedures. The AutoBrush is designed to eliminate those factors and leave you with less sensitivity overall.
How does AutoBrush's blue LED light whiten teeth?
The blue LED light in your AutoBrush speeds up the stain-lifting abilities of the whitening ingredient hydrogen peroxide found in the AutoBrush gel pens, allowing for whiter teeth at a faster rate.
