These 2 Crest Whitestrips Kits Are Bound to Sell Out During Amazon’s Cyber Monday Sale

Best for Beginners

This PureWow-favorite comes with 14 treatments (each with one upper and one lower thin, flexible strip) that conform to the shape of your teeth. They're coated with a tooth-whitening gel that's supposed to remove stains below the enamel surface. And it uses the same ingredients that dentists use. The kit also comes with two treatments of 1-Hour Express that are meant to give you same-day results for a visibly brighter smile (ooh la la).

Best On-the-Go Kit

If you're looking for a faster way to whiten your teeth, this kit is seriously one of the best. It comes with a tool that looks like a tube of lipgloss, only it emits a toothpaste-esque emulsion you swipe onto your teeth. The tool is small enough to stick right into your purse, making it super travel-friendly. The formula features five times more active peroxide droplets in the base and is meant to gently whiten teeth without irritation. Plus, the built-in applicator makes it easy to use at any point during the day (like before a job interview or a date).
