These strips work well. Unfortunately--and therefore the three star rating--the box I bought contained two dried and unusable strips. That's twice this has happened. Hey, Crest, work on your quality control. Then you'll get your fourth and fifth stars.

I am a fanatic about my teeth, and this product does exactly what I want! I have a whiter/brighter smile! I use the crest 3D professional white strips (whole box) twice a year! Some sensitivity at first, but doesn't last. I think everyone should give this product a try, it is well worth it and the money!

I automatically saw results within 3 days of me using these. Thesews are the best srips I have ever used and I am extremely glad I made this choice. There is no residue and there is no gooey mess! If you are having a hard time picking strips, I can tell you these are the one for you.

After my daughter had her braces removed, her teeth were looking a little dingy. We purchased the Whitestrips and OMG her teeth are absolutely gorgeous now! Thank you Crest for the great new smile. As a mom, I was thrilled to be able to buy a product from a company I trust and not break the bank either. You're the best!!!

So,I'm teenager and you know how important look is to almost all of us.As a child I wore braces because my teeth were looking wierd.I never smiled because of it.When came time for taking it off I was so happy .But my teeth were dark cause I had some problems with brushing my teeth.It's hard to brush teeth when you have braces.So I were shy again and never smiled.One day my mum bought me Crest 3D White Whitestrips and at first I didn't believe in it cause it sounds like miracle.I tried them and I suprised so much.Today I have Hollywood smile and boyfriend who loves me and my smile.The both of us use Crest 3D White Whitestrips now.Thank you Crest 3D soooo much!WE love you!Greets from Anna and Martin :*

First time that I used Crest 3D White Whitestrips Professional Effects I could see the difference. I was instantly hooked on the white smile it provided me day one! I would recommend to anyone who is looking for some white pearly whites to make your smile shine!

I've used these before and each time they do the job! I went about 2-4 years in between whitening and they stayed pretty white, with just brushing with crest 3D white toothpaste! Of course, using the strips again recently, has made my smile even whiter! I do recommend the LUXE professional effects as they stick the best and perform the best.

I bought a pack of this last year and used it once a week for 4 weeks and people starting noticing my whiter brighter smile! I stopped using it for awhile because I didn't want to over whiten my teeth. People love comparing their teeth to mine. I now use one once every 3 months.

I've had a great experience using these strips, and they have kept my teeth white for years after! I get asked all the time how my teeth are so white and I say I used crest whitening strips a couple years ago and they can't believe it! Awesome product!

[This review was collected as part of a promotion.] Ok I have naturally yellow teeth but these actually worked on my teeth. I used the old system before and they didn’t stay on my teeth but let me tell you these do not move! They didn’t hurt my teeth either! This is their best system yet that actually works.
