I love these! They work so well and actually stay on your teeth opposed to sliding around. The only negative I have in regard to these is that fact that when I say they stay.....they stay! Peeling them off takes some effort and you’re left with the residue from the “glue”. Other than than, I love using these!

This product is very effective and very easy to use. The only downside is- if I try to suck back the spit buildup (I know, gross) then I get shooting pain through my teeth. I have multiple family members who have this sensation no matter what they do when using this product. But, I have continued to use this product as it is affordable and works well into my nightly routine. As warned on the box, it can make your teeth a little sensitive for a few days after use, but I only occasionally noticed this and it was not sensitive enough for me to change any food or beverage consumption.

I loved these strips! I have extremely sensitive teeth, which is usually a result of irritated gums, and traditional strips are flimsy and don't stay on my teeth and I end up with whitening gel all over my gums. Not with these - they stayed put, didn't cause sensitivity, and really work!! I will absolutely buy these again.

I like that they help whiten your teeth, the downfall is the price, as well as the taste. It tastes horrible and doesn't work as great as you would like considering the price point. I will be trying different products to see if there is a cheaper or more effective alternative out there. 

These products completely are changing my life I am in recovery now almost 3 years sober but have always struggled with appearance issues and my teeth weren't so white after carelessness and ciggerettes smoking. My teeth are getting whiter I'm loosing weight and starting to love myself again and because of this product I love my smile again.

I never really noticed too much of a difference in my teeth while using these, along with toothpaste, mouthwash, and floss of course. I used the whole box over a couple of months and noticed barely any difference. They're suupppperrrr expensive so I definitely will not purchase again!

Crest white strips, especially these, helped my teeth get whiter than ever before. A lot of people commented on how white my teeth had gotten and always asked how I did it. My reply was always "Crest White strips and crest whitening toothpaste". Crest white strips always get the job done for me when I feel like my teeth are looking a little yellow.

Ow. I didn’t think I had sensitive teeth until I used this. Honestly, my teeth have never been the same. I feel like any whitening I try hurts now which kinda sucks. I didn’t even finish the entire box because my teeth hurt so bad, so I never noticed if they made much of a difference. Oh well.

I've been using crest 3d whitening strips for over 3 years and I find myself always getting compliments on how white my teeth are. On a regular I would say I drink at least 4 cups of coffee A DAY, sometimes more -_- so this product definitely keeps my teeth from yellowing. Highly recommend crest 3d whitening strips!!

[This review was collected as part of a promotion.] I’ve tried Crest whitening toothpaste and the original crest white strips previously and had good results but didn’t expect to have such great visibly noticeable results so soon after only using three of the white strips. I am a daily tea drinker and use turmeric white often in my food and drinks, so my teeth weren’t as white as they could be. I usually use a teeth whitener to upkeep my teeth but didn’t notice a huge difference in the color of my teeth. After 3 uses of these white strips for only 10 minutes per whitening session, my teeth weren’t drastically whiter. The only downside is I noticed my teeth became sensitive after the first use. I was afraid of tooth sensitivity so I lessened the recommended time of use and only put the white strips on for 10 minutes. I had to use Sensodyne toothpaste in combination with these white strips to prevent further tooth sensitivity, but they do work and made my teeth at least 3-4 shades whiter than before. I plan on using the rest of the white strips in the kit, but I wanted to spread them out further throughout the next few months to give my teeth a break from the sensitivity.
