1. Whiten your teeth by using color correction technology. Balance different shades of your teeth, mask stains and enhance brightness. 2. Color correction starts with the color wheel, where purple and yellow are complementary colors, opposite each other. When you apply purple to your teeth, you neutralize and counteract the yellow undertone, creating a noticeably lighter white. 3. We found the perfect dark purple to neutralize the yellow. A new way to clean your teeth. Non-invasive whitening treatment. 4. Our tooth color corrector combines two water-soluble dyes to remove any shade of yellow, giving you your brightest smile without leaving any residue. 5. Clean your teeth without hurting your gums, giving you more beautiful, whiter teeth.
