It's not often that you find a product that actually does what it claims to do, however, the Crest Professional Effects White Strips give you professional results while costing 90% less than whitening with a dentist. I am always receiving compliments on how white my teeth look. I enjoy red wines, coffee and tea, which cause staining. The Crest Strips remove these stains easily.

I gotta say, I was skeptical... I'd read all the reviews prior to purchasing and was still skeptical.... But I gotta tell you, I am so glad I tried these! I am a smoker and a coffee fanatic and was worried that they might not work for me - but these white strips work! I did experience some sensitivity, but I highly recommend this product! Don't think twice! If you're thinking about trying them, do it - you'll be so glad you did!

The three whitening levels on the 3D line are visible, dramatic, and professional. Naturally, my expectations for the Professional Effects strips were very high. Unfortunately, my results have been extremely disappointing. I even went so far as to supplement the strips with the 3D mouthwash, toothpaste, and brush. Still the results are barely noticeable at best. Crest gets a point in the performance category as the new advanced seal strips do a great job holding to teeth. But at the end of the day, it’s the whitening that counts. And these strips lack the ability to whiten at anything remotely close to a professional level.

I received it as a part of my Christmas gift from my husband last year ( He knows me really well... I am a teeth freak). It turned out to be one of my favorite gifts. My teeth felt clean and sparkly. Coffee staining diminished as well. And now I truly hope to get a new box this coming December!

[This review was collected as part of a promotion.] Thank you so much to Influenster and Crest for sending me this product to try in exchange for my honest review! I have used this product before and I love it so much! It truly is the only thing that really works for me. It does burn and can cause sensitivity if you use them too often or keep them on too long, so just be careful because of that. However I think this is a great value because you get so many strips in the pack for a price that it much better than professional whitening and can be used in the comfort of your own home. I do produce a lot of saliva after using, but I like to put them on before the shower so I can easily spit out the excess. They are not too comfortable but you get used to it. My only real problem with these is that keeping them on for a full hour is a long time. However, I believe that they do sell ones that you keep on for a shorter amount of time. Thank you again to Influenster for sending me this product to try!

[This review was collected as part of a promotion.] I love coffee but I don’t love what it does to my teeth. I want the whitest, brightest smile possible and Crest 3DWhitestrips Professional Effects Teeth Whitening Strips lets me have the best of both worlds. They’re easy are easy to use and after just one use, I can see the difference.

I've used regular whitestrips in the past but these strips work much faster and are much more comfortable to wear. They don't slip off your teeth at all, and I saw that my teeth were much whiter in only 2 days. Will definitely keep using this product.

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 :)

I have been purchasing this product for about a year now and love them more every time. The very first time I used the whitening strips I was already getting compliments. I am always asked how are my teeth so white and recommend the Crest 3D whitening strips to friends. Amazing product. Highly recommend!

[This review was collected as part of a promotion.] The crest whitening strips are the original whiting method I ever used and continue to be effective! The only issue I have with them is that my teeth get really sensitive but I have really sensitive teeth
