Love these crest white strips! I use them regularly when I have an event or something to go to and they don't make my teeth super sensitive like some teeth whitening products do.

The whitest smile in years after using Crest Whitestripes. My co-workers comment all the time how white my smile has been. I, now, am ready to make another purchase. I will always go back to using this product.

I really liked these whitening strips. I noticed a difference within the first 2-3 days of using them. They did a great job at whitening my teeth. However, they did leave my teeth a little sensitive. I wouldn't recommend for extended use. 

I use these whitening strips about twice a year (I love my wine and coffee lol) I definitely see s huge diference after the 4 th day and by the 7th day my teeth look like they've been whitened at a doctors office

I love having white teeth at all times. I'm a repeat user and will continue to use for sure! I alternate days to prevent teeth from becoming too sensitive. They work fabulously for me :)

This was very effective at whitening my teeth. It's a good product for getting it done in a short amount of time. Using it caused a little minor pain, but no long term negative effects.

I use the entire Cesar 3D white line and am extremely happy with the result. My dentist has also noticed a positive change in my teeth. I would recommend this product to other, especially people with coffee stained teeth!

This is the only whitening strips that I will use because they actually stay on!! I use this before my workout or on the way to work. It really works and I get asked all of the time what Whitening products that I use and I recommend this

Still using and waiting for results! I think that in order to see results it has to be used completely! I have heard my teeth are whiter so I think it is working. Can be a little pricey but cheaper than professionally whitened.

I really like these. They work very well and you can see a noticeable difference right after you use them. They do leave your teeth a little sensitive if you leave them on too long but the feeling usually goes away in a day or two.
