In our guide to the best teeth-whitening kits, the Crest 3D White Professional Effects Whitestrips came out on top as the best teeth-whitening strips. The kit comes with 22 treatments and it works quite simply. First, you peel the strips — one for the top teeth and one for the bottom — from the backing. Then, you stretch and apply them to your teeth. After 30 minutes, you remove the strips.

You should see results in as little as three days. After completing a full 20-day treatment, the results are meant to last for 12 months or more. If you just want white teeth now, the kit also comes with two treatments of 1 Hour Express strips that remove stains in just one hour.

If you feel like your smile has lost its luster over the years, be it from coffee, wine, tea, soda, smoking, or any other staining habit, whitening strips might be your best score this Prime Day.
