Crest whitestrips truly live up to my expectations. My teeth were noticeably whiter after one use.

I got a few samples. I only use the strips for close weddings. Teeth did whiten a bit, but I wouldn't use these every day or week. It's bad for your teeth.

This stuff is pretty expensive. To keep my teeth white I squish a capful of hydrogen peroxide in my mouth. It's also good for the breath.Why should I pay elaborate prices when I can get the job done for a fraction of the price?

As stated in the editor's note, these products may cause tooth and gum sensitivity - which I experience. The product is good as I did notice that my teeth were whiter after use, it's not worth the pain. My teeth ached really badly for hours after I used the product to the point where I had to lay down and wait for the pain to subside. Definitely not worth the effects or cost. However, I realize not all people experience this and in such cases, this is a great product.

My best friend is a dentist and he says that these strips are just as effective as teeth whitening in the office. I have been using these for years and my teeth are pretty white. As long as you don't overuse them, they are great

The strips wore quite comfortably which was nice but they did nothing for the teeth. I could not see any difference whatsoever.

I received a sample of these and was not impressed. They fell off my teeth and there was no difference in the whiteness of my teeth. They also tasted really bad.

I had a sample of these and was hesitant to use them because of the advisory about sensitivity and I tend to have sensitive teeth. Anyways, I decided to try them and not only did they not work at all, but they did hurt my teeth quite a bit. I definitely won't use them again.

I am very fortunate to have never worn braces and still have straight teeth. My lower teeth are a little crooked and I did find it more difficult to get the strip to cling to all of the ins and outs of my teeth. Despite this, I am very impressed with the results. My boyfriend noticed right a difference right away although, this is not to say that my teeth were really yellow to start with! They definitely needed brightening and this did the trick! I will say that I do have some sensitivity whenever I use the strips for a few days following the treatment. I will use a sensitivity toothpaste to help with this however if you are willing to wait it out regular toothpaste is fine. I do find the price a bit high but if you go online you can often find coupons to help offset the cost. I also recommend using a whitening toothpaste to help keep your pearly whites white.
