Teeth whitening is one of the easiest and most effective at-home beauty treatments you can do. It only takes a few minutes of passive effort a day to brighten your smile by a few shades. The downside—teeth whiteners can be pricey. But in a very exciting early Amazon Prime Day deal, the cult-favorite Crest 3D Whitestrips are on sale. The teeth-whitening box—which comes with 28 strips—usually costs $45, but this week, it's on sale at 41% off for $26.

Crest Whitestrips have been around for more than 10 years now, and they've gained quite the following. They have more than 15,000 reviews on Amazon, an average review rating of 4.5 stars, and most importantly, our Good Housekeeping Institute Beauty Lab found they're worth the hype. In recent tests, our pros named Crest 3D Whitestrips a top at-home teeth whitening product, calling them the "gold standard for smile brightening." Tests showed that after 20 days of daily use, teeth were two to four shades lighter.

Crest claims that the hydrogen peroxide strips provide "professional-level" teeth whitening results, removing 14 years of stains in just 30 minutes. The strips have an advanced seal technology that make it possible to talk and drink water while you're using the strips to whiten your teeth.

And if you're looking for quicker whiting before a big day or photoshoot, the brand is also slashing prices on its Whitening Emulsions (also loved by the Good Housekeeping) and 1 Hour Express Whitestrips. If you're looking for a surefire way to whiten teeth at home—and at a great price—now's the time to buy!
