PSA: Crest Whitestrips Are on Sale at Amazon for Black Friday 2022

How does it work? It's actually really simple. The set comes with 44 thin, flexible strips that conform to the shape of your teeth. They're coated with a tooth-whitening gel, which removes stains below the enamel surface. These strips are made with the same ingredients that dentists use, so they're totally safe. They also work, according to the more than 70,000 Amazon reviewers who swear by them. In fact, if you use them for 30 minutes a day, Crest claims that you'll even start to see a brighter, whiter smile in as few as three days.

Oh, and the kit also comes with two, one-hour express treatments that give you same-day results for a visibly whiter smile (ooh la la!).

We know what you're thinking: No wonder so many people are stocking up on Crest Whitestrips while they're 10 percent off. We highly suggest getting yours before it's too late, so you can rock some pearly whites for your next event.
