You would think theyre paying me to write this but seriously is such a great product. Ive been using them every other day already for a week and I could already tell the difference. I have 2 white stains on my front teeth (stains that have been there since I started growing my adult teeth) anyway, that little area is so white it makes the rest of my teeth look really yellow! I love to smile but its always on the back of my mind that people can notice my yellow teeth. BUT NOT ANYMORE! I smile more confidently and notice it every time I glace by a mirror or any reflection. Its great. I'm so happy with this product. Worth the buy!

I have experimented with many different "whitening" products, including the professional trays and product you get at the dentist. The professional stuff definetly worked but is much more $ in the end (trays and gel). I liked how this product stayed put, and I didn't leave a nasty taste in my mouth. The best part is it's 30 minutes, and not an hour! Crest has definetly improved their product with the "stay put' strips, and the effects that it has after just 1 use! I did my first application this evening, removed the strips and my teeth just look brighter!!!! An A+++++++ product!

I've been using these since march 2015 and I inmediatley noticed my teeth to be whiter but it wasn't until I compared pictures from before and after that I realized how much whiter my teeth were. They really work and now I really have a more luminous smile. I think I'll start using two packages per year so I see even better results

Purchased the original Crest Whitestrips some years ago and was pleased. I am not a smoker, coffee or tea drinker and only experienced minimal whitening with the 3D Pro Effect strips. Not remotely close to a professional whitening.Frankly one could probably achieve the same results from a whitening toothpaste!

[This review was collected as part of a promotion.] I’m no stranger to white strips. I usually use the sensitive teeth version, but the results with those are pretty meh. I’m happy to say these Crest Whitestrips didn’t make my teeth super sensitive. I used them every other day as opposed to daily to be on the safe side. Not perfect, but I’m happy with the results considering I’m a coffee and wine drinker and spent 4 years in braces (which does a number on you). Would def purchase this product!

Crest 3D Whitestrips are definitely effective, and they work fast to make teeth super white. The only draw back to bleaching teeth is that your teeth feel sensitive for a bit after (no hot or cold drinks for a day or two) but the dazzling white effects make it worth it, and it's much less expensive than going to the dentist for the same thing.

Hello my name is Brittney and i would like to say these whitening strips are remarkable i was worried because i don't trust bleaching as far as dental bleaching but i was amazed how these whitening strips work happy to say that my smile is a non stop in the streets and i love looking at them will definitely be keeping my smile up. Thank you, Brittney

I do not recomend this product since you will have sensibility after use it.I'm not saying that in a profesional bleaching you wont have it but imagine having sensibility for 14 or 20 days.That is ridiculous.I am returning the product because it is not worth,I want my money back

I had not visited my dentist in years and he told me that my teeth looked better than people he had coming in twice a year. I told him I had used the Crest 3d White Strips. Before I used these he had warned me years ago that I had some staining that would never go away. I showed him. These work...I had mild sensitivity but nothing too bad. Definitely will be going to get a new box soon.

I started using Crest 3D White Whitestrips, twice a year, for the last three years. Every time I visit my dentist, he expressed his amazement at the whiteness of my teeth. I had to have a porcelain crown made for a molar that has caused me grief since I was 17 years old, and the dentist struggled to find a porcelain white enough to match the rest of my teeth! Of course he was eager to find out what I'd been doing to keep my teeth so sparkling white, and I was more than happy to tell him Crest 3D Whitestrips Pro Effect :)
