I use this 2 week set and also the pack that you use during the 6 months between when you’re supposed to use this. I love this and see a visible difference every time I use them. They’re a little pricey, but only buying them twice a year makes me not feel as bad about spending the money.

Yes these work ! I was wowed I’ve been using them for a few years now and I rarely do it anymore but my teeth are pearly white , it will probably sensitive on your teeth at first but it’s well worth it trust me look at my Snow White teeth . Thank you Crest

This stuff is as close as you're going to get to at home whitening that is professional grade.  It does give you zingers, so beware of those.  But if you can stand those or if you do not have super sensitive teeth, this product is def for you.  My teeth always look super white with it! 

[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

My brother used to use these and every time I he’d visit his teeth would catch my eye because of how bright they were. He recently gave me three of these and I’ve definitely noticed some results. I didn’t brush my teeth for a year or so when I was younger so it’s really reassuring to know there’s something that could quite possibly fix the damage my younger self did to my teeth.

I've tried everything to get perfect white teeth! My teeth were always a light yellow color, I never wanted to smile with my teeth I was so not confident with my teeth. So i decided to buy the teeth whitener. Best purchase I have ever made! Now I can be happy with my smile. And very confident. I get compliments all the time now about my teeth, and about what I did to get them so white. My answer is, "Crest 3D whitening strips!"

So I’ve use 3 different kinds of there whitening stripes (glamorous white, vivid white, and professional effects) & this one is my 2nd favorite. These you keep on for an hour & honestly they hurt my teeth keeping it on for that long. But I will say, they are very effective! They are also the most expensive ones, but they do work the best. I prefer the glamours white because you don’t keep them on as long.

You buy products and are never sure they are going to live up to the claims it states on the packaging. This product does exactly what it claims it is supposed to!! Money well spent and wonderfully white teeth result just like going to the dental office!

After using this for a month and seeing virtually no change, I have decided that this product is not effective. I wish it would actually whiten the teeth and not just leave a bad taste in my mouth every day. It is also quite expensive as a product. Not worth it in my opinion.

Loved these whitening strips. I definitely noticed a difference just after the first few days. It was quick and easy and I didn’t even use up all of the strips before I got to my desired shade of whiteness. The only thing i didn’t like is sometimes they were hard to keep on and would slip around on my teeth. Still got the job done though.
