I like the whiteness of my teeth at the end of the 2 hours. They are very easy to apply and use.

Oh hey completely white teeth! This strips are worth the money - wait till they go on sale and you're a real winner! They work flawlessly, I find my teeth don't even get too sensitive afterwards! Completely worth it.

Instead of going to the dentist these strips are a lot cheaper and work as great as the dentist . my teeth are so white, i get compliments everyday

Loyal user of crest white strip the never let me down! And yes they work!

Recently quit smoking and thank god for these my teeth have never been so white, people keep asking me how and I'm not keeping it a secret.

Tried this & I really do see the difference. You have to try it to believe it. I have older teeth & it still worked. I will buy it again. I tried it on half my teeth so I could see the difference, good way to see how it works.

the advance level for works fantastic.

This is a great product for whitening your teeth and really transforming your smile. It will takes years off your smile and this product is great for smokers or people that feel that their smiles are not white enough. This will give you lots of confidence in the whiteness of your smile.

Easy to use & nice outcome as teeth are getting whiter & taste is ok

Crest 3D White Professional Effects Whitestrips definitely works. I have always taken really good care of my teeth so they are pretty white before using this product but I wanted them whiter. After trying this I noticed a big difference after the 4th day. The only problem I had with this product was it made my teeth very sensitive which it said it would with some people. I found a solution to the sensitivity by using Colgate sensitive Pro relief an hour before applying the strips. It totally made a difference and I could use them without discomfort. I really like this product and will continue to purchase. It's cheaper then going to the dentist and it works! I would recommend this product
