Why is it a good deal?

At $34, this is the lowest price we've seen since last summer. So be sure to snag these Whitestrips now, and your gleaming teeth will match your winter whites!

Why do I need this?

Most of us eat or drink things that leave our teeth a lot less white than we'd like. But this kit promises to lift stains from your chompers' enamel to reveal a smile that's 12 levels brighter in just 10 days. The kit comes with 10 treatments, and the process couldn't be easier: You just peel, apply and let the strips do their magic every day for just one hour. That's it!

What reviewers say:

Over 2,700 have given these Whitestrips a perfect rating. "I was pleasantly surprised to see that the results were amazing," wrote this happy shopper. "The whitening is especially noticeable, because you see the results in two hours, instead of gradually over many treatments."

"I like this Crest 1 Hour Express because it whitened my teeth without making it look super-fake white," shared a satisfied customer. "The results look natural, and it only took an hour. Just put it on and watched an episode of The Bachelor and I was done! Quick and easy."

One smiling reviewer shared this advice: "I’ve used several of the Crest whitening strips, but this specific box is the BEST! I only used 3 of the strips and noticed a difference in my teeth, by the 6th time I used the strips my teeth were at least 3 shades whiter!"

For some people, it's a total game-changer. "I used Crest 3D Express Whitestrips on my teeth yesterday and am stunned at how well they worked," wrote this final fan. "I am a smoker and daily coffee/tea drinker and my teeth were stained to say the least. I always had to use the 'teeth whiten' feature on myself in my photo editing software. Not anymore, I'm happy to say."
