Crest 3D White Strips Gentle Routine (28 strips) offer a mild, effective whitening solution ideal for sensitive teeth. Designed with an enamel-safe formula, this kit includes 14 treatments—each with an upper and lower strip—used daily for noticeable whitening in two weeks. The strips contain the same whitening ingredient used by dentists and feature a no-slip grip, ensuring they stay securely in place during application. Simply apply the strips once a day for 30 minutes to gradually lift stains from coffee, wine, and more. These gentle strips are perfect for first-time users or those looking for a low-sensitivity alternative to traditional whitening kits. Regular use helps restore a visibly brighter, cleaner smile without irritation.
