Yes. With Crest 3DWhitestrips, you can use one strip right after the other (back-to-back). Wear teeth whitening strips for the instructed time, then remove; rinse or wipe if needed, then apply a second whitening strip. To maintain your whiter smile, use up to two Crest 3DWhitestrips teeth whitening systems per year; or try Crest 3DWhitestrips Classic Vivid. These 30-minute once a day strips whiten and help protect your smile against staining. If you feel you need to whiten more frequently, we suggest you speak with your dental professional about professional-strength Crest 3DWhitestrips Professional Effects.
