Why isn’t a whitening toothpaste enough? A: Because you shouldn’t settle for a smile that’s just “white enough.” Every Crest 3D White Whitestrips teeth whitening system guarantees a whiter smile or your money back. See package for details. While Whitestrips and most whitening toothpastes remove surface-level stains, Crest Whitestrips remove set-in stains below the enamel surface for a visibly whiter smile. The real question is why wouldn’t you use Whitestrips? Q: Can Crest 3D White Whitestrips hurt my teeth or enamel? A: No! When used as directed, it’s a safe and effective addition to your beauty routine. Crest Whitestrips contain the same enamel-safe teeth whitening ingredient as dentists use to whiten teeth, so you can be confident that they’re safe. Q: How do Crest 3D White Whitestrips work? A: Here comes the technical jargon: Crest 3D White Whitestrips are thin, flexible strips that are coated with a tooth whitening gel. Designed to conform to the shape of your teeth, they work by keeping the teeth whitening gel in place against your teeth to remove stains below the enamel surface. Whitestrips use the same, effective whitening ingredient dentists use. They deliver the whitening you need where you need it for a brighter, whiter smile! Want to whiten your teeth at home? Crest 3DWhitestrips Professional Effects is designed to whiten like a professional-level teeth whitening treatment at-home. The Advanced Seal Technology's comfortable, no-slip grip means the strips stay put until you take them off, allowing you to talk and even drink water while whitening your teeth. Made by the #1 dentist-recommended at-home teeth whitening brand, Crest 3DWhitestrips Professional Effects will give you a 100% noticeably whiter smile. This enamel-safe, at-home teeth whitening kit will make your teeth 18 levels whiter. Simply apply Crest 3DWhitestrips Professional Effects for 45 minutes a day for 20 days.
