It whitens, but I'm fully aware of whitening teeth at home isn't super safe. I use every so often and it works, but I try not use it too often. The price is kind of up there, but for quick fixes it's ok.

These strips are an all time favorite! They really do the job. Not only do you get super white, glowing teeth, but it lasts for months! These strips remove all coffee stains for those who drink a lot of coffee!

I have tried all kinds of products to whitened my teeth and this one is the best. I saw some nice results in only a couple of days and it was really easy to use.

It was easy to use. It stayed where you put it on your teeth. I didn't notice a big change when I used it. I found because you had to leave it on for so long that it was hard to find or remember to use it all the time to make it really work.

Easy to use and fast results. Whiter teeth and removal of coffee or wine stains within a few tries. No teeth sensitivity if you follow the instructions. Professional whitening results.

Crest is the best whitestrips on the market. Unfortunantely, they are so expensive. Please CREST cut down on the pretty, expensive packaging, lower the price so I can afford to use them more.

Where would I be without crest white strips? These things are perfection. You only need to purchase them twice a year and you'll have beautiful white teeth year-round! I love these.

This product is great for whitening! It's super easy to use and doesn't make your teeth super sensitive like others. My teeth are definitely noticeably whiter when I use these strips.

They stick on your teeth well compared to other brands. My teeth were so much whiter after completing all the strips. The only downside is I had mild sensitivity.

If you want white teeth without having to pay the bill at your dentist this is the perfect remedy! 1/4 of the price, and the same results! If you have sensitive teeth I'd try them out because they can leave your teeth hurting.
