[This review was collected as part of a promotion.] This 3Dwhitestrip teeth whitening strips is one of my must have. I'm a heavy coffee drinker , i drink coffee 3 times a day every single day . I do noticed not but teeth have been getting yellowish. Having to use this 3D whitening strips helps prevent my teeth from even getting more yellowish. I also did noticed that my teeth have been improving from how it looks like before. This product works for me.

[This review was collected as part of a promotion.] As a person that consumes large amounts of coffee and tea, keeping my teeth white has been an ongoing struggle that has prompted me to buy just about every whitening product available. Every time Crest comes out with a new Whitestrips product I give it a try.

[This review was collected as part of a promotion.] I've been using crest whitening strips for years! I wasn't aware of the multiple options they have available with different levels of whitening (until now!). I have sensitive teeth naturally, and I try to stay on top of keeping my teeth bright and shiny - a dental freak if you will. Crest has been the one and only brand that gives me consistency, does not compromise my teeth sensitivity, and has others complimenting on my teeth. Literally nothing else compares. I've tried so many! I was so excited to see these pop up on my screen.

I've been wearing these consistently for just a short while and am already starting to see results! I feel so much more confident going out and showing off my smile. They also stay on really easily as I go about my day to day activities which I love! Very happy with this purchase.

[This review was collected as part of a promotion.] I have been using Crest 3-D Whitestrips for years when I feel I need a boost in my teeth whitening routine. These strips give you that Hollywood smile within a few weeks of usage, but you will see a difference in just a few days.

[This review was collected as part of a promotion.] I've been using Crest for years and absolutely love it! Using Crest 3D Whitestrips Professional Effects has become a part of my weekly routine and has made a huge difference in my smile and overall confidence. I recommend them to all of my friends!

[This review was collected as part of a promotion.] Definitely seen a color difference on my teeth during the first week of use. I don't like that I had to leave them on for an hour. Felt like it was too long, didn't feel them on my teeth but I did feel sensitivity on my teeth after using them because I use sensitive toothpaste. Love how my teeth looked after using them. If you can stand the sensitivity I would definitely recommend

So basically a bad depressive episode caused me to neglect my teeth and then endless amounts of coffee didn't help. After working myself out of it and finally taking care of myself, I still couldn't smile with my teeth. I was self-conscious. I thought about getting them professionally whitened but opted to try this. BOY. I saw results by the third day like the box said I would. By the fourth day, I could almost cry. I'm not done with my 20 treatments yet but this has seriously changed everything. It makes me so happy. I can't believe I could have just done this the whole time. Thank you crest, for this lovely product and giving me my smile back.

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

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!
