Smile Wide — Our Favorite Whitening Strips are Back Down to $30

Even if you diligently brush twice a day and floss every night, your teeth might not be as white as you’d like. Crest’s 3D Whitestrips really do get the job done though, and you can grab a box with 22 1-hour express treatments for $30 today, the same price they sell out at on Prime Day. Don't just take our word for it. Reviewers rave about these strips, saying "Finally found something that actually works for my coffee-stained teeth!" and I never thought I'd get rid of the yellow-ness of my teeth...but this stuff works!!" You have to put in the time to make sure they actually work, but boy howdy the results are worth it.

These whitening strips are a best seller every year for Prime Day, and with good reason. They offer professional level whitening, with up to 19 levels whiter teeth. That would take a lot of time and money at the dentist, which is seriously no fun. All you have to do is place the strips on your (not so) pearly whites for 45 minutes for 20 days, and voila! Whiter teeth without the dentist office anxiety. This deal won't last forever though, so run now and get these #1 doctor recommended strips while they're at their lowest price. You won't regret it.
