My brother used to use these and every time I he’d visit his teeth would catch my eye because of how bright they were. He recently gave me three of these and I’ve definitely noticed some results. I didn’t brush my teeth for a year or so when I was younger so it’s really reassuring to know there’s something that could quite possibly fix the damage my younger self did to my teeth.

I’ve used these in the past and had great results. My teeth remain white and every once in a while I will re use for maintenance. The only con is the sensitivity. I would honestly use them more often if they didn’t cause my teeth to feel so uncomfortable. The sensitivity goes away within about a week of ending use though.

Use these strips if you want pearly whites! I usually use them once every other week, and that’s plenty. Your teeth may get a little sensitive the next day, but it’s worth it. You get a good amount of strips and they’re very effective. Highly recommend.

I love this product so much! I have been using these for years and always get compliments on how white my teeth are. They are easy to use and worth the price for sure. I definitely recommend for a quick boost of whitening! I will definitely continue using these.

Before I got trays professionally customized at the dentist for whitening, I used these strips. These strips are effective in what they do. I notice a difference in whitening just after one use of these strips. However, the only negative is that my teeth are SO sensitive after using these strips. Drinking or eating anything cold afterwards is quite uncomfortable. But, for the job that they advertise to do, it's a gem. 

I have normal stains like everyone else and I needed something other than toothpaste to get rid of them and make my teeth whiter. These strips worked so well. My teeth are so much whiter and the strips didn’t hurt my teeth or gums or cause an irritation. I highly recommend this product.

I've been using Crest white strips for several years now and have been extremely satisfied and happy with their results. It's not the results I'm disappointed in, but the fit of the latest version that I purchased which have a terrible fit for your bottom teeth! In the past, Crest made the bottom strip smaller/shorter & it fit great, but now it's the same length as the top strip which makes it difficult to place on your bottom teeth. It also doesn't stay in place toward the back on both sides and now that you need to leave them on for a full hour (rather than 30min. twice a day), it's not comfortable....my husband is in agreement! I hope Crest will consider going back to the other smaller strips for the bottom teeth in the future!

The crest 3d white strips have been the amazing key to my beautiful bright smile. It is my holy grail. Whenever I have a special occasion or an important meeting to attend, all I have to do is slip these on my teeth for about thirty minutes and BAM! I feel confident and glamorous . It is worth every penny!

I’ve been using Creat products for years. My dentist and and the person that cleans my teeth always ask what I use because my teeth are so white. My response is always Crest. They are impressed but also my friends comment on my teeth also. I’d say Crest whitening products are the best I’ve found so far on the market.

These definitely work great! They whiten quickly and easily. I used to use these all the time with no issues, but as I have grown older, it seems my teeth have gotten more sensitive & when I try to use them now it makes my teeth hurt. I just have been using the toothpaste alone instead.
