Supersmile Professional Whitening Accelerator features a professional-grade formula designed to be used in conjunction with Supersmile Whitening Toothpaste to give you a radiant smile. Exfoliating acids remove tough surface stains from your enamel while urea-buffered peroxide improves overall tone without irritating the rest of your mouth. It also restores vibrancy to bonding veneers, lightens bleached teeth and even dentures.
