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!

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.

[This review was collected as part of a promotion.] I was really hopeful about these whitening strips, since my teeth are a little yellow from soda stains. These didn’t really do much for me at all, they whitened a little bit but within days they were back to how they were before, even when I only drank water. These made my teeth extremely sensitive for hours after only wearing for 15 minutes. I’m sure they would work better if I could use them more than once a week but the pain from the sensitivity is too much for me, especially since they haven’t worked too well for me. Hopefully this changes over time or maybe I should invest in sensitive toothpaste, but I’ve had a better whitening experience from a dollar tree whitening gel- no joke! This is not worth the money, they’re definitely overpriced. It comes with a lot of strips but it hurts so badly.

I never write reviews but I had to for this. I have been using my first pack for 4 days now and I can see a huge difference. I was really worried about the sensitivity because I have very very sensitive teeth, but I just had very slight sensitivity in one tooth for the first 2 days and now nothing. This product really works. My only downside is with crest as a whole... they said you get 10% off when you sign up with your email, however when I got the code and entered it, it said it wasn't valid.

This whitening product has been effective for me multiple times over the past few years. I have used it in correlation with other Crest products (such as toothpaste) and I have seen a noticeable difference. They only negative thing I would have to report is that it occasionally makes me teeth sensitive to heat and cold, but overall, I love the Professional Effects!

[This review was collected as part of a promotion.] We love the comfort, sensitivity and packaging of these white stripes. They do a good job at biting our teeth quickly and effectively. The value is great because you can do that. I’m at home and it cost way less than going to a professional.

I was very nervous at first, however, I jumped the gun and purchased the professional effects. Right now I have used 16 out of the 20 strips and I am so happy with the results. I used to have really yellow teeth and the treatment so far has lightened up my teeth at least 3 to 4 shades. It is very much noticeable to the point where I may not even need the extra 4 strips. The only side effect (as expected) is the teeth sensitivity (though no gum issues for me), which lasts about 3-4 hours post treatment and goes away after that. I rarely ever post reviews but I am very pleased with this product that I felt compelled to do so. Will definitely repurchase in the next few years.

Needless to say with no fanfare. Crest 3D White Whitestrips Professsional Effects are by far the most effective most whitening whitestrips on the market. They are easy to use, affordable and after you get through using them the compliments just keep coming in. People notice a difference right away. They will improve your self esteem and you will find that smile of yours again!

[This review was collected as part of a promotion.] I have always wanted to try these white strips but I realized they weren’t right for me. I have gone to get them professionally whitened about three times and have always experienced extreme sensitivity pain afterwards. With this product I have to wait 2-3 days until the next dose due to pain. It is simply not worth it for me. I rather get instant results one day and take pain pills instead of these week treatment. If you don’t have my issue you should give these a try they are reasonable priced and are easy to use and after using it for a week I did see my shade 1 shade brighter or at least a slight difference.

[This review was collected as part of a promotion.] These whitening strips are easy to use and effective. I see a huge difference in the color of my teeth just after one application. However, I don’t like how sensitive my teeth feel after use for at least a good 24 hours.
