FYI: Crest Whitestrips Are a Top-Selling Item for Prime Day & You Still Have Time to Get Some

Want to brighten your smile? Say no more—the Crest 3D White Professional Effects Teeth Whitening Kit will get the job done in no time, and the results last for a year or more.

BTW, the kit is a top-selling Prime Day item, and it's almost 50 percent off right now (!)

How does it work? It's actually really simple. It comes with 44 thin, flexible strips that conform to the shape of your teeth (FYI: they're coated with a tooth-whitening gel) which remove stains below the enamel surface. An easy way to think of it— they use the same ingredients that dentists use, so it totally works, and it's safe. (Bonus: if you use them for 30 minutes a day, you'll even start to see a brighter, whiter smile in only three days.) Oh, and the kit also comes with two treatments of 1 Hour Express that gives 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 still 44 percent off.

Get yours before it's too late.
