I noticed 3 shades difference first time I used it

[This review was collected as part of a promotion.] This definitely worked!!! I noticed about 3 shades difference my first time using. The actual strips were comfy to wear and easy to apply! Easy to read directions as well!

Adheres Well, no sloshing!

What I like about these strips as when they are on your teeth, there is not a lot of movement if any. They feel like they are almost clinging to the teeth, which is more comfortable and easier to wear for a longer period of time....great upgrade!

Whiter teeth

[This review was collected as part of a promotion.] Who doesn’t like white teeth. I love this line, but it does make my teeth a little sensitive. But it’s a quick solution for whiter teeth but it’s a little pricey. However I recommend.

Amazing

[This review was collected as part of a promotion.] Who doesn’t love a 3-D white strips. I never knew as a kid how important it would be to have white teeth as an adult and these 100% help get my teeth to the desirable whiteness I want.

Worked in some spots

This product worked well in some spots. But after a few days in other spots it started to wear off and need new treatments to make said spots white again! Over all very satisfied with the product. The spotting issue would be my only complaint!

The whitest teeth I have ever had.

I bought these crest whitening strips 1 week ago and my teeth showed such an improvement in 2 days. I'm on day 4 and the difference is outstanding. I have the whitest teeth now!

Bad Purchase

This product did absolutely nothing for me, I used the entire box and was left with no different result, quite disappointed. Satisfaction not guaranteed, and still no refund. I would never waste money on these products again.

Didn’t work

Unfortunately these did nothing. I did have some slight sensitivity here and there. The last kit that I used wasn’t directly from crest do I thought maybe that was the issue but this kit didn’t work either.

reply from The Crest Team

We're sorry to hear that this has been your experience, and we hope you're feeling better. Safety is at the heart of all we do here at Crest, and we can assure you that our Whitestrips have been thoroughly evaluated to be safe when used as directed. The whitening ingredient peroxide - the same enamel safe whitening ingredient dentists use for tooth whitening - is at a level that's in line with regulations. However, some users may be more prone to sensitivity than others. There are steps you can take to reduce/eliminate this sensitivity, such as not brushing too hard, or more than twice a day during treatment, and using a softer toothbrush. As well, our Whitestrips go through many quality checks to ensure that you can enjoy brilliant results with them. Consumer testing and clinical studies have shown that Whitestrips are effective. However, if you have stubborn stains you may need to use a second box of Whitestrips to achieve the results you want. We'd also like to mention that you shouldn't exceed a total of 2 kits per year. We hope this is helpful, and we'd like to gather some more details for our Safety and Quality Teams. When you have a moment, please give us a call at (800) 395-8423.

Slow but great results

I been using the strips for about 2 weeks and I can see a litter shade on my teeth. Is not surprising because I was expecting a longer proces. The process is slow but I am getting great results.
