No change in whiteness at all!

I bought the box of 20 treatments--40 strips. Used them faithfully each day, and was hoping for at least SOME whitening. What a waste of money! My teeth look exactly the same as before using the strips.

We always want our Whitestrips to give you an amazing whitening after thorough quality testing which we stand behind with our Crest Money Back Guarantee, so it makes us so sad to hear you didn't see these results. In some cases teeth stains have been known to be stubborn, and need additional treatment. If you'd like to share more or learn more about that Money Back Guarantee, feel free to give us a call at (800) 395-8423. We'd love to hear from you.

Big improvement already!

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).

it is great product

I bought this whitestrips, it is cool. This is one of the most effective whitestrips for teeth whitening. Crest is the best brand if you want to get white smile. And if you want that everybody ask...ohhh..you have so white smile.

Absolutely great whitening stripes

This was my second order for the 3D Whitestrips. First box lasted me over 2 years! Great product and my dentist and hygienist compliment me on how bright and white my teeth are.

URGENT: uneven whitening on tooth

May I know why there's an uneven whitening after my first use of 3D professional effects white stripes? Should I continue or stop using the remaining white stripes? Hope to get your reply soon.

At Crest, there's nothing more important to us than showing off your smile to the world confidently, so we're sorry you're seeing uneven whitening results. These aren't the results we expect especially if the Whitestrips are firmly aligned with your gum line and the strip is folded behind the teeth to keep it in place. At this time, we recommend discontinuing the product, and to get in touch with our team to talk about your experience. We can be reached at (800) 395-8423 Monday-Friday 9:00AM-6:00PM EST.

Excellent results and easy with no pain

The absolute best whitening process! These strips whiten quickly without the stinging gum pain or tooth sensitivity. I threw away the expensive, messy gel from my dentist and will only use these strips!

Awesome

[This review was collected as part of a promotion.] These have been great. I've used this for three days and can already tell a difference and I am beyond happy with the results. I don't like the flavor but that happens.

QUICK RESULTS

[This review was collected as part of a promotion.] This had QUICK results! I definitely noticed a visibly whiter smile. It was painless and I love how each is individually wrapped. I think it was a great value for how well the product works.
