Watch This Video The CELEBRITY WHITE LED Light uses the same type of light technology used by many dental offices to whiten patients teeth. The power of LED light safely penetrates tooth enamel and help activate the Carbamide Peroxide whitening solution (gel). The blue light speeds up the whitening process and the red light has healing properties which will help decrease any chance of teeth or gum sensitivity. Although our products are safe, we have gone the extra mile to make your whitening experience the best it can be. Carbamide Peroxide safely whitens because it more slowly (slower than Hydrogen Peroxide) releases the oxygen in the whitening gel which creates whiter teeth. We add Potassium Nitrate Fluoride to reduce any chance of tooth sensitivity and it also strengthens enamel as you whiten with our serum (gel).
