Honestly, I've never been in such tooth pain. Used it ONCE for the correct amount of time, and the pain kept me up all night. I still can't eat or drink and it's the next day. My teeth are on fire and my gums are throbbing.

I started using these strips 10-15 minutes a day for a week and within 3 days there was a huge noticeable difference. After that week I only use one strip a month for 25 mins to keep my smile white. This product works fast and is very effective.

So easy and such an obvious difference. Pic at night, in same artificial light, comparing before and after 10 days/treatments (so half of a full course).

When coffee, tea, and life keeps trying to darken your smile, use these little miracle strips to combat that by brightening and whitening your teeth! Smile Big and Bright with Crest 3D White Whitestrips! :-D

I have used these many times in my life. But this 2020 year, I skipped taking care of myself. I took a picture 2 weeks ago and now (2 weeks use). See for yourself, the difference is visible

Hello, I tried this product and everyone immediately saw the difference. I love the way it brightened my teeth. Thank you so much for making dental hygiene not only healthy but attractive

I saw a wonderful difference in my teeth after a week! so I stopped and now I am just saving them for when it gets closer to holidays for the perfect smile!(:

I honestly tried many things to whitening my teeth's I heard about the white strips and it was amazing it worked great! It's unbelievable I loved it and I can honestly reccomend it to anyone!

Love the product - but on my last two usages (same box) for the upper teeth - the peel off did not peel off. The whole sheet came out perfectly and I cannot get the top to peel off. Please tell me what to do. Thanks

I have tried all kinds of products to whitened my teeth and this one is the best. I saw some nice results in only a couple of days and it was really easy to use.
