Our patented cool blue LED light technology (the same blue LED light technology used in dental offices) activates our gel formulation, which makes whitening your teeth faster and deeper and keeps them their whitest longer. This has revolutionized cosmetic tooth whitening in a manner that is safe, effective and pain-free. Anyone over the age of 14 can whiten their teeth. Parental consent is required for persons under the age of 18. It is safe for Crowns, Caps and Veneers, and stains will be removed during whitening, returning to their original color. It is the # 1 choice for anyone with Tooth Sensitivity. This is a whitening system for people that experience sensitivity from other in-office dental whitening treatments, take-home dental trays, or over-the-counter whitening systems.
