I like these whitening strips because they are nice but they have a weird taste. I use them about once a week or every two weeks and after I use them I notice a small different. I have used these for awhile but they often fall off of my teeth which is kind of annoying but still pretty cool product

I have been using Crest white strips for YEARS! I love how they keep my smile bright and I always get compliments on how white my teeth are. I personally have to use the kits that take a couple of weeks due to my teeth sensitivity but it's always worth it!

I find many options in whitening strips to be a tad expensive. When using I have to make sure I will not need to talk for awhile. Any movement talking etc. tend to move the strips and they begin to raise up and are not as effective. Product does seem to whiten teeth when used.

I absolutely love crest whitestrips. I tend to use them more often leading up to a special event. I used them frequently leading up to my wedding and my teeth were pearly white for my bridal portraits! I also have sensitive teeth and these strips don't irritate me or cause more sensitivity.

Does the job but makes my teeth very sensitive after so I have to be very careful how frequently I use these. I personally don't love how long you have to keep them on your teeth and the feel of them, but teeth whitening isn't supposed to be an amazing experience :) but the sensitivity isn't fun.

I get asked all the time if I've had my teeth professionally bleached, and I owe these strips for that! I followed the instructions on the first box and now I'll use them every not and then for maintenance. They can make your teeth sensitive when using them a couple days in a row, so I try to prepare for that using toothpaste designed to help combat sensitivity just while I'm using these.

I loved the whitestrips. I noticed a difference after the first use. I received a whitening system (trays and bleaching solution) from my dentist and was told to wear them overnight. Not comfortable at all. I can put the Crest 3D whitening strip on before I take a shower, leave them on until I am finished and see a difference. I have already recommended the to all of my friends and will continue to do so. Thanks Crest for making a great product that is also so easy to use.

I really like this product. I drink a lot of coffee and I love red wine both of which can cause teeth staining. I use these strips 3 times per week and I get great comments on my smile, especially in photographs. I've gotten my daughter and fiance to use these too.

[This review was collected as part of a promotion.] I’ve been using the Crest 3D Whitestrips Professional Effects for a few days now, and I’m honestly impressed with the results. The strips are super easy to apply, and I love that they don’t slide around while I’m wearing them. After just a few uses, I noticed my teeth looking noticeably whiter. There’s a slight sensitivity, but it’s nothing major. Overall, I’m happy with how much brighter my smile looks, especially for a drugstore product. If you’re looking for an at-home whitening option, this one’s definitely worth considering!

This is a really great product that I found to be worth what it costs. It whitened my teeth many shades even though I did not use it daily (I used it more like every few days for a month or so, then kind of “as needed”) and it really grips onto teeth - you can even drink water with them on. As always, you do need to read directions carefully. They occasionally cause some sensitivity for up to a day after but it's not a problem as long as it's expected. Note that the Crest website often has amazing two-for-one deals on these kits!!! Even more worth it!
