Wow, this thing really works. After a couple of uses, saw a big difference in the color of my teeth. Downfall is it causes sensitivity to my teeth for a couple of days after using it. I use it less often now. I would recommend this to others. Try it out!!!!!!

Just started using these a little over a week ago and I'm loving my results! They are easy to apply and instead of waiting 30 minutes I wait around 45 minutes. My teeth get a little sensitive after taking them off but after a hour the sensitivity is gone away.

This is a big part of keeping my teeth the brightest white that they could be. I use this along with their extra whitening tooth paste daily. It does brighten your smile and deliver results. My teeth are the whitest white that they could be. This product is available at a very fordable price. And it definitely beats the price of paying for teeth whitening at a dental office. I like that I can use this kit in the convenience of my home and it takes a fraction of the time that it would at a doctors office.

This product works great. I bought it a few weeks ago right before going to a photoshoot and I am so happy that I did. It is very effective. I used it once a day for thirty minutes for seven days and there was a drastic change. I would highly recommend this to others.

After speaking to my dentist she recommended I tried the Crest 3d white strips and after the first 3 times I was hooked! Not only were they brighter but somehow shiner too! They looked more youthful and glowy again! I've always struggled with my smile and even after brushing 2x a day I still wanted something more and these strips were it!

I have tried other teeth whiting products and none can be compare to Crest 3d white. This product is awesome and I have refered it to all of my family members and friends. On the first day I used the strips,toothpaste and mouth wash people noticed how white my teeth were,I had great results on the first day of using Crest 3d white. People were telling me how bright and white my teeth were. I now have a new smile thanks crest 3D white.

Knowing you can drink coffee or tea and no guilt feeling about the drink staining your pearl whites... 3-d crest say your back. THE feeling oh ahhh my teeth are only to be white and glowing for the holidays and everyday. feels nice someone has our backs and not our packets ... The product is amazing for the price. if you like comments about your smile this iz a product for you :)

The fit is a bit off and it's not very comfortable. The taste is not pleaseant either. But they stay on and they do what they're supposed to. My teeth are noticibly whiter. Just make sure to read the instructions and use them all. Overall I'm satisfied and probably would purchase again.

It's inexpensive for at home whitening. It definitely works and whitens your teeth. I'm terrible at remembering to do it everyday but I did every other day and it did whiten my teeth about 4 shades whiter. I would recommend not to use it every single day because the gum and teeth sensitivity sucks.

These do realllly whiten your teeth! After a couple uses I saw a visible difference and people actually started to ask and notice! However after awhile it made my teeth sensitive. When I would put them on my teeth would have bad pain, but I would recommend just don't over use!
