I had very yellow stained teeth, now that I used this product it did not leave them pearly white like I wanted, but my friends have noticed that they are whiter. I will buy a new box in hope that it will get them the kind of white I want them to be!

This was great for whitening my teeth in between dentist visits and getting ready for big events where your smile has to be on point. I would recommend this product for those once in awhile needs.

I've use this product a couple times and I am definitely not impressed with it at all. The strips did not want to stay on and I never saw any results.

You will absolutely see results pretty much immediately after using the crest white strips. I don't know of any competitor products that do the job quite as well and that are as convenient as the strips.

i am very self conscious about my teeth. however this product helps me fight that! i put them on while i drive to work or do my makeup and that's so easy !

A little messy and I wish the packaging the strips came in was more convenient. I do feel like I had dramatic whitening after only two or three uses, but I experienced a lot of sensitivity and had to pause using them.

These are pricey compared to other brands, but they definitely work. I noticed a difference after two or three times. My teeth are sensitive to this kind of stuff so I did have some discomfort and sensitivity after using.

These are so great! I saw a difference in teeth coloring after 1 use! Easy to administer compared to other similar products, not a lot of residue left behind.

It did make my teeth a little more sensitive but not a lot. I noticed a difference in my teeth being whiter however it wasn't that great and some people's

These work very very well. I could see a difference after just once use the next morning. They can make your teeth very sensitive so be careful about applying them every day. I usually take a day break between applications.
