OverviewContrary to what most people believe, not all whitening toothpastes are the same. In fact, most whitening toothpastes are designed to remove surface stains. New Colgate Optic White whitens teeth with hydrogen peroxide – the same whitening ingredient as strips, but at a gentler, lower 1% concentration – making it a convenient and affordable way to whiten every day. Get whiter teeth in 1 week, with results that improve with daily use, and optimal results within just 4 weeks.
