Colgate Optic White Renewal is a fluoride whitening toothpaste built around 5% hydrogen peroxide, a level most drugstore whitening pastes don't reach. Colgate says it lifts years of tea, coffee and wine stains with twice-daily brushing over two weeks, while fluoride fights cavities and supports enamel. It suits people who want deeper whitening than abrasive-only pastes offer without a dentist visit. The trade-off is a stronger peroxide taste and possible sensitivity, so it is not the gentlest pick for everyone.
