[This review was collected as part of a promotion.] Starting off strong with a simple yet attractive package that is easy to open! The strips are super easy to remove from packaging and apply to your teeth. Directions are simple and the results are amazing. You wear these for 45 minutes at a time and after just the first use, I definitely noticed improvement in whitening on my teeth! happy to say that I haven't noticed any tooth sensitivity so far after 3 uses now! The strips stay stuck to your teeth during the full 45 minutes, which is awesome because there has been other ones that stay very slippery and tend to slide off

I bought these for my husband who decided to whiten his teeth after using chewing tobacco for 17 years. His teeth were actually stained brown. Within 1 day we saw a difference, and by the time he was finished there were 17 years of chew tobacco stains completely gone. Fantastic, impressive results!

[This review was collected as part of a promotion.] Really like how fast you can see the results when using these whitening strips. After 3 uses my teeth look brighter, without sensitivity. They're comfortable to wear especially the fact that they must be worn for an hour. The strips are wide enough for those with bigger teeth so there's a Pugh surface area. Overall, these will be my go to strips when it's time to buy another pack.

[This review was collected as part of a promotion.] I absolutely love these Crest whitening strips. They are extremely easy to use and come in little individually wrapped packages per use. I noticed my teeth looking brighter after just a week and multiple shades whiter after 3 weeks. I'm a coffee and wine drinker so I definitely had some noticeable staining to get rid of. They do cause a little sensitivity - when I noticed that I started using the strips every other day and that helped a lot. I'm really impressed how much whiter my teeth look!

[This review was collected as part of a promotion.] Impressive Results in Just One Week! These Crest Whitestrips are super effective my teeth looked visibly whiter after a few uses. They're easy to apply, comfortable to wear, and stay in place. I had mild sensitivity, but it didn't last long. Each strip is individually packaged, which makes it convenient and hygienic. For the results you get, the value is definitely worth it!

I am so impressed with these white strips by Crest. I had used this product in the past when it was very messy and there was all kinds of gel on there and the strips so the strid would slide. And if you left the strips on too long, they would really cause pain on the teeth. But this version is perfect. 30 minutes a day and by the time I finished the box, my smile was far whiter. Made me feel great! My dentist suggested Crest White Strips!

[This review was collected as part of a promotion.] The crest whitening strips are the original whiting method I ever used and continue to be effective! The only issue I have with them is that my teeth get really sensitive but I have really sensitive teeth

I have used these before and they have always worked. However, this last purchase does not work. I was send old out of dated ones that have no stick to them at all. I ended up throwing them out. What a waste of money. I will never purchase from these people again

[This review was collected as part of a promotion.] These white stripes work amazingly well! I saw a noticeable difference in the whiteness of my teeth after one 45-minute session. I have sensitive teeth, and these strips did not hurt my teeth or cause any additional sensitivity. Each set is an easy to open package that is small enough to be able to pack them if necessary. There was a lot of bubbling that you could even see while the strip was in place, whitening I could see!

[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!
