I was very nervous about buying this. Not only was I skeptical about its ability to remove 14 years of stains but I thought spending money on something ineffective was stupid. It turns out, I was the stupid one for doubting this amazing product! I finally got this product and my teeth are so much whiter now. All the stains from coffee and tea are totally gone. It didn't even hurt my teeth! And my teeth are very sensitive. Please do not waste your money on other teeth whitening products. Free advice-Get this! Coming from a smart shopper, this product is totally worth every penny.

When I have an event coming up I can use Crest 3D White Professional Effects Whitestrips Teeth Whitening Strips Kit 40 Treatments Twin Pack once in a week and see a difference. These whiting strips don’t leave my teeth feeling extra sensitive. I feel they are cleaning while protecting them. I would highly recommend them and they are worth their price.

These are nice but if your teeth are sensitive you might want to give them a break every so often they do work they are just sometimes a bit of a hassle because of the fact that they do make you feel a little bit uncomfortable if you are sensitive to whitening if you’re not wanting to pay the professional price this would be a great option

My main resining for loving these is because they don’t budge when on the teeth! These whiten more “over time” not a one time use kind of a thing. But I always get compliments on my teeth and when I tell people what I do different, I usually get a response in a few weeks saying these strips are working great for them too!

[This review was collected as part of a promotion.] I absolutely love these! I will start by saying I have very sensitive teeth, and I had no issues with this product! They were so comfortable with zero sensitivity problems. They apply easily and bend right over the teeth so they can be fitted properly. Once applied they stay put without slipping! One hour a day for one week, and my teeth were SEVERAL shades whiter! My teeth are glistening like they did when I was a teenager! I’m a coffee drinker….. like a constant coffee drinker, so I struggle with coffee stains. Well, no more thanks to these! I cannot wait to use them again!

I CANNOT SAY ENOUGH. These work and are my absolute favorite line. To see the best results you really have to be consistent in using them but they really do work. I 100% recommended this to people and have never felt any adverse effects. Crest 3D White Luxe Professional Effects Whitestrips Teeth Whitening Kit

My, my, I am so glad I have been using Crest 3D White Whitestrips. To me, it is the best strips that have been put on the market that is sold in stores. I get so many compliments after using my strips. Crest you have done a marvelous thing for regular folks like me. Thanks to you Crest, I can smile all day in the office.

The new crest professional white strips are the best thing ever made!!! I noticed a change in the color of my teeth within 3 days.My family & friends all noticed & asked what I was using.They are so easy to use & they stay in place & do not slide off.I can not believe how well they whitened my teeth.

I had a coupon, I figured what the heck. I am sitting here with my teeth clenched together for the last 20 minutes now because almost as soon as I put the strips on, the slid back off. They do not stick well at all. Because i spent the money, I am going to try and complete the whole ten day regime. Given this poor initial performance, I honestly do not expect any worthwhile results.

Finally, a product that meets and exceeds it's advertising claims! I am 52, smoke and drink lots of coffee and as a result, my teeth had yellowed badly. I have used Crest whitestrips in the past with fairly good results, but the twice daily application was messy and time consuming. Professional whitening treatments were not in my budget, so I gave these a try. After just one treatment my teeth were whiter than after a month's use of the old strips. Crest 3D also removed a dark spot on my front tooth I'd had since childhood that had remained despite routine dental cleanings. I was so pleased with the results that I bought a box for my daughter. Thank you for a wonderful product!
