These strips make your smile not only healthy looking but YOUNG looking too...nothing says age like off color teeth....no matter how much you spend on your wrinkle creams....NOTHING makes a more obvious, quicker difference than whiter teeth! And these strips are easy, effective and stay PUT! I love these strips and it is part of my beauty routine...a MUST.

I really did like this product. Drink coffee and I do smoke so as a dental assistant I felt like my teeth could be whiter and I purchased and I did see a difference with in a week I did get sensitive to it so I had to get toothpaste for that but it does work and I do record as long as YOU DONT HAVE resin fills or crowns in front teeth as those will NOT change colors and it will stand out as your teeth get whiter.

These are definitely my favorite whitening strips. I only use them before special occasions and events but they do make a difference. I use them every other a day the week before I have some sort of event and they work. They can make your teeth sensitive so I don't recommend using them regularly, but it's a good product.

As a daily coffee drinker these are lifesavers!! I didn't want to pay for an expensive whitening treatment and it wasn't too much of a hassle to do this daily though the taste was really gross and it made my teeth extremely sensitive so I had to switch to sensodyne toothpaste to make things easier.

I honestly loved these at first J began seeing a difference although I hated the texture and taste of it. But I have a cap on my tooth because I chipped my tooth a couple years back so underneath the cap is exposed nerve making it very sensitive. The paste basically stripped the layers of my cap away till I could feel the exposed nerve 24/7. It was hell and I then had to get the cap removed and get a new one. Maybe the package says this somewhere or I was being really dumb but just be careful and know what ur dental history is like. I hope this helped!!

I've been using crest 3d whitening strips for over 3 years and I find myself always getting compliments on how white my teeth are. On a regular I would say I drink at least 4 cups of coffee A DAY, sometimes more -_- so this product definitely keeps my teeth from yellowing. Highly recommend crest 3d whitening strips!!

I really like this product and it was recommended to me by others. It made my teeth really white which I love! I have sensitive teeth so if I need to space it out between using. It can hurt your teeth if you use it multiple times a week. It's worth the price because it comes with so many!

Been using these for about a year and they work amazingly. You can see your teeth whitening from the first use! Super easy to use. The only negative thing is sometimes it bleaches my gums for a short period of time but goes away within an hour. Love using this and will be a customer for life!

I have been whitening my teeth for years, I go thru spurts where I will whiten for 3 months at a time. Usually I find that my teeth get a little sensitive... I've been using these crest white strips for the last month, daily use leaving them on for 30 mins and I have NO sensitivity. my teeth are dramatically whiter, and they are easy. Would highly recommend!

I received it as a part of my Christmas gift from my husband last year ( He knows me really well... I am a teeth freak). It turned out to be one of my favorite gifts. My teeth felt clean and sparkly. Coffee staining diminished as well. And now I truly hope to get a new box this coming December!
