Hace dos meses empezamos a usar estas tiras,mi esposo tenia los dientes muy amarillos y en 3 semanas sus dientes se aclararon mucho,él está muy feliz pues un blanqueamiento en el dentista es super caro,en cambio en mis dientes no he notado mucho cambio,quiza porque los mios no han estado amarillos,pero tampoco son super blancos,al menos sé que funcionan y no nos produjo ninguna sensibilidad ni dolor y lo malo es que no siempre pegan bien,algunas tiras parecen no tener mucha fuerza para pegarse a tus dientes y se resbalan

I recently had the fortune of sampling Crest's 3D White Strips and I am SOLD! They have done away with the messy residue! The strips are easy to apply and stay on without moving or becoming uncomfortable! My teeth are noticeably whiter! The new white strips are easy to apply, comfortable to wear, and leave no mess or bad taste in your mouth. I have already recommended them to friends and family and will definitely be a repeat buyer!

I use Crest 3D White Whitestrips Professional Effects on a monthly basis because I love how beautiful they allow my smile to look! I drink black coffee daily and red wine on a semi-regular basis, but with these whitestrips I have had no problem keeping a "movie star white" smile! I love this product and would recommend it to anyone wanting to enhance the beauty of his or her smile.

[This review was collected as part of a promotion.] These crest white strips are so helpful when you need a quick teeth whitening! I’ve used these for a couple days now before bed and I already notice a difference! It’s gradual but definitely there! I’m hoping for even more after a few weeks of use! They are a little tricky to apply but I’m starting to get the hang of it. I found that making sure your teeth are somewhat dry helps them stick better. Eat at home whitening!

I was very nervous about buying this. Not only was I skeptical about its ability to remove 14 years of stains but I thought spending money on something ineffective was stupid. It turns out, I was the stupid one for doubting this amazing product! I finally got this product and my teeth are so much whiter now. All the stains from coffee and tea are totally gone. It didn't even hurt my teeth! And my teeth are very sensitive. Please do not waste your money on other teeth whitening products. Free advice-Get this! Coming from a smart shopper, this product is totally worth every penny.

What is the first thing people notice? Your skin and your teeth. If yoiu want to make the best impression ever then get your teeth super white with Crest White Strips. I use Professional Effects and they are life changing. My teeth are beautiful and I owe it all the Crest, thank you! Super easy to use, fast and no mess.

[This review was collected as part of a promotion.] Thanks Influenster, for the free Crest 3DWhitestrips.. the packaging was not great, but that may have been due to shipping. These strips worked ok, I noticed a slight difference. I dd have a slight sensitivity to it.

These Pro Level Whitestrips are super easy to use. I asked my dental hygenist which products work and she suggested these after my cleaning. Boy was I happy with the results! I used them for a little over a week until I was happy with the brightness and now I get compliments all the time! I just repeat after every cleaning for 2-3 days to maintain. Highly recommend!

I drink coffee every day and it stained my teeth. I'm on a limited budget so I couldn't afford a professional cleaning. When I got a coupon for 3d white strips I decided to give them a try. Much to my surprise my teeth came out the whitest they have been since high school I will definitely use again when needed! Thank you Crest for making whiter teeth affordable.

I have tried many home remedies for teeth whitening for years until I finally came upon crest 3d whitestrips. I saw a very noticeable difference within one week. My gums are also sensitive and they did not effect them negatively. Amazing product and I plan on purchasing again.
