[This review was collected as part of a promotion.] I was impressed with the Crest 3D White Strips Professional Express — the packaging is sleek and easy to use, and the strips stay in place comfortably. They noticeably whitened my teeth in just a few uses, making them super effective and a great value for quick results. I did experience a little sensitivity, but nothing too harsh and it didn't last long. Overall, an easy and fast way to brighten your smile!

[This review was collected as part of a promotion.] I love the way these strips make my teeth whiter and brighter. They don't make my teeth sensitive or anything, and it doesn't have any flavor, just like any other whitening strips still not the most pleasant feeling but it makes my teeth whiter so, I'm happy with that. I wish the time was a bit shorter like the other whitening strips because this one you have to hold for 45 min. Other than that, these work great! I received this product complimentary for testing purposes.

[This review was collected as part of a promotion.] Thank you so much to Influenster and Crest for sending me this product to try in exchange for my honest review! I have used this product before and I love it so much! It truly is the only thing that really works for me. It does burn and can cause sensitivity if you use them too often or keep them on too long, so just be careful because of that. However I think this is a great value because you get so many strips in the pack for a price that it much better than professional whitening and can be used in the comfort of your own home. I do produce a lot of saliva after using, but I like to put them on before the shower so I can easily spit out the excess. They are not too comfortable but you get used to it. My only real problem with these is that keeping them on for a full hour is a long time. However, I believe that they do sell ones that you keep on for a shorter amount of time. Thank you again to Influenster for sending me this product to try!

[This review was collected as part of a promotion.] These whitening strips are easy to use and effective. I see a huge difference in the color of my teeth just after one application. However, I don't like how sensitive my teeth feel after use for at least a good 24 hours.

[This review was collected as part of a promotion.] I tried the Crest 3D Whitestrips for a week and while they did noticeably whiten my teeth, I did experience some tooth sensitivity along the way. The strips were easy to use, but I noticed a few spots where the whitening solution seemed more concentrated, which led to uneven results in certain areas. Some parts of my teeth are whiter than others, so it's not a perfectly even transformation. They work, but I'd recommend being careful with placement and maybe using them every other day if you have sensitive teeth.

[This review was collected as part of a promotion.] I'm the number 1 fan of these Crest whitening strips. They are effective and a good price. I love that I can do it from the comfort of my home, and people ask what I use because my teeth are white. This kit is super effective, the best package for your whitening teeth, like the professional whitening Yes, I highly recommend it. Thank you
