All I can say is wow!! The first day I noticed a change! It's like having it done at your dentist without the big price tag! I use it about four times a week the first week. I achieved my desired shade and now it's once a week and I drink coffee!

I'm glad I tried thses #Crest3D white strips. I noticed a change in the coloration of my teeth the first week after using these strips. So I'd be buying this product from now on.

It really works! If i felt sensitivity i just skipped one or two days and continued using it. I feel much better now that i can smile without being selfconscious of my teeth!

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 LOVE my crest whitening strips! I get compliments all the time on how white my teeth are! I've tried other products and nothing ever compares! I will always be a crest fan!

VERY EXPENSIVE. But my boyfriends had extras and let me try them. I'm absolutely in love. It's just very hard to keep my teeth white, so this helps a lot

I've been using It for 5 days now and already see a huge difference. Although it's expensive and not a necessity, I am pleasantly surprised at how well this works and am eager to see my results after I am finished

I used this for the full 20 days and I didn't see any results. I spent money that I don't really have right now on it, and really wanted it to work...I ofcourse lost my receipt so I am out of that money...Oh well :(

I loveeee these white strips, they work so good. After one use you can see the difference. Rather than paying a fortune at a dentist you can do it yourself at home.

While they obviously don't work as well as a professional teeth whitening, these are a good at home option. They don't irritate my teeth but I've heard from others that they can have that side effect.
