Q: Are you supposed to keep mouth dry after applying? What if saliva keeps getting on teeth?
A: Unlike toothpastes and paint-on gels which dilute and wash away quickly, Crest 3D White Daily Whitening Serum includes highly active peroxide droplets suspended in a water-resistant base to whiten teeth with virtually no sensitivity. Our unique formula is enamel-safe for daily use and stays on your teeth longer to continue whitening long after you apply with no need to rinse, brush or remove.
