[This review was collected as part of a promotion.] While I use crest toothpaste these strips did not work the same for me. It whitened my teeth a little bit, but left them in so much pain! Having to leave them on for a full hour is also super inconvenient.

It's so amazing, that it really works. I am soon 24-year-old and I have had since childhood yellow teeth. I don't smoke but i drink coffee and sometimes but rarely red wine. I have a healthy lifestyle. I was really skeptic and sure that doesn't do anything to my teeth. But I want it to try, so I used 7 strips half of the year. Now i can see in the mirror and photos that my teeth is naturally white and I have lot of confidence to smile too. Enamel is not damaged and doesn't feel uncomfortable, they also stay place. salivary flow was strong with the strips. I will use them again. I can warmly recommend, be surprised positively!

I love them, 3D WHITE WHITESTRIPS PROFESSIONAL EFFECTS they do work! The only thing that I found wrong was that on occassion I would pull the whole plastic piece off instead of just the strip and then it was a pain to get the strip off. But it was worth the hassle. WOW these things work. The BEST!

I used the product 3D Crest Whitening Stripes a few months ago so I could have the whitest smile at prom. Within a week or two, I was more than happy with the results! All my friends were complimenting how white my teeth were and it gave me the biggest confidence boost ever. I've always wanted a beautiful white smile! To keep up with the wonderful whiteness, I use 3D Crest Whitening Toothpaste that tastes better than toothpaste should taste. It's honestly the best product I've ever used to keep my teeth clean and white. I plan on using the whitening stripes again this winter because I just LOVE having a perfect white smile! It's fast, easy to use, and 100% the best decision I've ever made.

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 received this product complimentary to review for my honest opinion. The packaging and instructions were straightforward, making the strips easy to use. For maximum results, reframe from drinking beverages that will stain your teeth. I would recommend this product.

For someone 73 years old, this does a fairly good job of making my teeth look less yellow. However, the other day I opened one of the packets to remove the strips, and the strips came away with the back still on them. Perhaps someone could separate them, but I could not, so I opened another packet. I was able to release the upper strip but not the one for the lower teeth. This is a rather expensive product to have to throw away. I would mail these to you if requested to do so. In the meantime, the numbers at the top of the packets: (L)4003V435 Thank you

I am done with two weeks so I only have a few more days to go and so far there is no change at all in my teeth! I purchased this because it came up as the second leading strip whiteners out there and it is easy and I like how well it sticks and no mess but super sad there is no results at all, I totally wasted my money

So my teeth were always kind of yellow looking, even though I brushed and flossed everyday..so I bought the crest 3D Professional Effects white strips and crest 3D Luxe toothpaste, and noticed remarkable results after just one use of the strips, has definitely gave me more confident

After only 2 uses I noticed a whiter smile. Im axious to see how much it improves with each use. The upper strip stays in place perfectly, no slip, and its not messy..My only complaint is the bottom strip. It needs to be longer. I have had some trouble with the lower strip staying in place and not sliding around. Overall tho, great product and is totally worth the price!
