Led Light

[This review was collected as part of a promotion.] This is a great product. At first, I worried that the light was just a citchey addition, but i think it actually enhances the effectiveness of the white strips. This product has definitely noticeably whitened my teeth.

Works great

My teeth are pretty sensitive, but I've had no problem with these at all. And they work! I'm surprised at how well they whiten teeth. They don't even taste bad. I only have two "drawbacks" and they aren't really drawbacks. 1. If you have spaces in your teeth.. which I do... you can see shade differences on the sides. Not much they can do about that though.
2. They aren't easy to come off, you have to pull pretty good. Then paper towel and rinse off. Again, no big deal. Overall, very very pleased.

Well worth it.

[This review was collected as part of a promotion.] These work great on my teeth! 🦷 I have sensitive teeth but have not had any major problems using these. Also, consistently using these help to keep my teeth whiter. The package has a considerable size of strips for the price.

Good!

[This review was collected as part of a promotion.] I bought these whitening Strips a month ago and I have had great results using them. I have used whitening strips in the past, and they all seem to have made my teeth very sensitive. This product, however whiten my teeth without making them sensitive. I love the strips and would recommend them to anyone.

Great results

[This review was collected as part of a promotion.] I love having white teeth and have been using white strips for decades now, but I've always hated how sensitive my teeth got when using them, so I was super excited to see that Crest had come out with this special kit specifically for sensitive teeth. I've had zero tooth sensitivity after use, managed to use the whole kit without having to take a break due to pain and the results are just as good as the regular white strips. I just picked up a pack for my husband who has sensitive teeth too!

[This review was collected as part of a promotion.] I've done regular white strips years ago and had great results. I thought I'd try the sensitive kind now. Before I talk about the actual process, I do want to note that I use whitening toothpaste daily, prior to using this product. 
The strips are easy to apply. I recommend “airing out” your teeth for a few seconds before applying. They make it awkward to talk and there is a little bit of an awkward flavor, but pretty mild. You leave them on for 30 minutes, which I'll admit, was a lot of time some days, so I skipped it and resumed the next day. Then, you put the LED light in your mouth, on your teeth. It is easy to keep in your mouth and the light turns off on its own. When you take them off, it leaves a gel residue that you need to brush off. 
The process isn't terrible and my teeth aren't any more sensitive than before, so that's a plus. However, my results aren't great. My teeth are maybe slightly whiter, but not much. They weren't overly yellow before, but I expected a little more whitening. These will probably work better for someone that doesn't already use whitening toothpaste, since it is meant to get rid of stains. In my photos, the top is after, bottom is before white strips.

Not sure

I bought this a week ago and holy cow the mistake I made when purchasing.My teeth are killing me can't even get through the night without be in excruciating pain. It feels like a thousand needles are being pushed down into my mouth all at once.Woke up about four or five times last night because of how bad my teeth hurt.Do yourself a favor and DO NOT buys this product

Horrible

I kept trying to hold out hope that these would work for me but I'm on the last two days of strips and I see absolutely no improvement. This really sucks because despite having amazing oral hygiene, my teeth are a very obvious yellow and these whitening strips couldn't even reduce the yellow or make it lighter! I wanted to feel more confident with my smile and now I just feel embarrassed for wasting my money.

No changes, doesn't work

For the last 2 times I bought these, there was nothing but a little bit of sticky stuff on the strips. These used to whiten my teeth so well and my teeth would be beautiful and sparkling white but since you guys have come out with the new formula of the NO SLIP.... it does not work, there is nothing on the strip except the stuff to keep it from slipping around on your teeth which didn't give me a problem to begin with anyway. And no they were not old on the shelf either. You need to drop these and go back to what you were first making, they were great ..... I WILL NOT be buying anymore of these ever! I have been using Crest products since I was a teenage and I am 63. This is a real disappointment!

This Product does not work anymore!

Crest white strips are a wonderful product and work great. The reason I wouldn't recommend the "no-slip" version, is that it really sticks to your teeth. If you have fillings, the original (not the no-slip) product is be a lot less stressful to use. The one time I used the no-slip type, I was worried they would damage my fillings. I'll continue to use and recommend, great product, just will use the original version when I can find them.

Use the original product if you have fillings
