The secret to a Hollywood smile might be easier (and cheaper) than you think.
More than 100,000 shoppers have purchased Crest 3D Whitestrips in the last month alone, and they have plenty to say about them.
Reviewers rave that these whitening strips are not only easy to use thanks to the no-slip grip and advanced seal technology, but they’re also surprisingly effective. The popular whitening kit includes 22 treatments plus two bonus treatments, promising “professional-level whitening” — and it’s currently on sale for nearly 25% off on Amazon.
“I had some dark staining to my teeth that made them look very yellowish,” one reviewer shared. ” I’m 43 and am a coffee drinker. I have never whitened my teeth before either. I used the whole box, applying these once a day as directed. My teeth look AMAZING!”
Other reviewers are sharing their before-and-after photos as proof, and the difference is hard to miss.
Crest Teeth Whitening Strips

The key ingredient in these whitening strips is hydrogen peroxide, a common whitening agent also used in professional dental treatments. Crest describes its formula as “enamel-safe yet powerful.”
And while the brand suggests it can take up to 22 days to see the results, many report noticing the difference sooner.
“I have to say I was blown away by how well these worked!” another reviewer shared, adding photos from her treatment journey. “A friend who works as a beauty editor recommended them, saying they were the best (affordable) teeth whitening option on the market, but I still wasn’t expecting such a big difference in a short time.”
For best results, the brand recommends using one treatment daily for 45 minutes. If you have sensitive teeth or any known allergies, be sure consult your dentist or healthcare provider before use.
