[This review was collected as part of a promotion.] I am really glad I found some strips that work on sensitive teeth.  These strips are very easy to use.  No slipping or sliding.  I like these because you can use them and go about your normal activities.  They fit to the shape of your teeth and are easy to get off.  These strips are gentle on your teeth.  I have noticed a noticiable difference.  I think the value of these strips is great.  I highly recommend.

Really like these

crest.com

[This review was collected as part of a promotion.] I tried whitening strips many years ago and found they hurt my teeth, so I was excited to see these much newer version for sensitive teeth. Everything you need is included. The strips are individually sealed and are so easy to stretch and apply, and they didn't hurt my teeth! I like how they come with an ultraviolet light to boost your treatment. The light is also so easy to use. It's on a timer so it's goof proof. Just put the mouthpiece in your mouth and press the buttons. I can't wait to see what my teeth look like at the end of this box. I noticed they are slightly whiter already, after just a few uses.  I will definitely be continuing to whiten with Crest 3D Whitestrips

Perfect for sensitive teeth

[This review was collected as part of a promotion.] I found these white strips easy to use, packaged nicely, and they didn't irritate my sensitive teeth! There are enough strips for a 14-day course. I didn't need to stop using them during this time but, as with anything like this, it may make your already sensitive teeth more so. Also know that you'll need a solid 35 minutes for the treatment each day. That's 30 min to let the strips set on your teeth, then an additional 5 where the strips are still on and you use the LED light on them. One nice thing - the LED light doesn't stop working after the 14 uses so you can buy the strips again and use it for another treatment without having to spring for another combo pack. My teeth definitely look whiter, which is nice because I drink a lot of coffee and use a whitening toothpaste, but still needed some extra help. I'm not sure how long the brighter smile will last, but I like the product and am happy to buy another kit in the future.

Works great for my sensitive teeth

[This review was collected as part of a promotion.] I received this a month ago and I absolutely love it! I'm so happy  we got this. The instructions were easy to read and easy to set up. The process is quick and so easy. I am seeing huge results. I would definitely recommend this to anyone.The results are great!

Great products!

[This review was collected as part of a promotion.] I really enjoyed these crest strips! These feel comfortable on the teeth and seems to work quicker at whitening then other strips. The LED light that came with it really made the huge difference. I've tried other strips without a light and they work but not as quick or good. The light is a huge positive add on to this product.

Noticeable difference

The only reason I didn't give it a 5 star is because the timer on the blue light did not work accurately. Sometimes it would do 4 minutes on each side and sometimes 5. The last week it kept turning off after 30 seconds and I had to keep starting it until I reached 5 minutes. It was quite annoying . My teeth are normally sensitive but this did not cause them to become more sensitive. So I was able to get a nicer smile without added sensitivity.

Good results

Wow! This kit is wonderful for sensitive teeth! Noticed a difference after only one treatment even with the lesser strength kit. Only thing I am not a fan of is the fact that the light device can not be reused once the 14 day treatment is complete. It would be great to be able to purchase just the strips In the future and just replace the light bulbs and batteries in the future. Would likely be better for the environment as well. Other than that it's wonderful. Thank you Crest!

Wonderful for sensitive teeth!

[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
