This is the Crest 3D White Whitestrips Sensitive kit, which includes 28 strips for a total of 14 whitening treatments. It is specifically designed to be gentle on teeth while removing years of accumulated stains. How to Use For best results, follow these three steps daily for 14 days: Peel: Open the foil pouch and remove the whitening strips from the backing liner. It is recommended not to brush your teeth immediately before application. Apply: Apply the gel side of the strip to your teeth, aligning the straight edge with your gumline. Press gently for good contact and fold the rest of the strip behind your teeth to keep it in place. Reveal: Wear the strips for 30 minutes once a day. After 30 minutes, remove and discard the strips. You can rinse, wipe, or brush away any remaining gel. Key Tips & Safety Sensitivity: If you experience tooth sensitivity or gum discomfort, stop using them for a few days before resuming. Enamel Safe: This product uses the same enamel-safe whitening ingredients that dentists use. No-Slip Tech: The strips feature a grip that allows you to talk and even drink water while wearing them
