Absolutely love the fresh icy flavour. After the fist brush my teet felt smooth and clean but after 2 weeks of using I can not see any whitening effect.

I really enjoyed using this toothpaste! It is with the money! I found the taste to be okay, and there was no aftetaste like with some other whitening toothpastes. I thought it really cleaned my teeth well; and makes it whiter after using it for some period of time

I think this toothpaste is probably better at keeping your teeth white than it is getting your teeth white. Of course Colgate recommends their entire system of products to achieve the best results---toothpaste, mouthwash, toothbrush, whitening pen---but I got more impact using Crest 3D by itself. I didn't mind the taste of this product, and felt it got my teeth clean; but whitening not so much.

As a smoker and coffee drinker, I need a toothpaste that will give me clean and healthy teeth and gums, as well as fresh breath. Colgate's Optic White does all this for me.

I couldn't believe the results after using this product. It was purchased at a sale price as my boyfriend was drinking a ton of coffee lately and he was unhappy with his teeth. We decided to purchase this and WOW! What a difference. It's not making my teeth sensitive and they are looking nice and shades whiter. He had just as amazing, if not better results. I have a Dental Cleaning due in a month and I already have noticed some stains have been brushed away. I await was the hygienist has to say :)

Have been using this brand for the last 6 months. Recently went to the dentist after not going for 2 years. I am a coffee drinker/past smoker. Dentist said i have very little staining on my teeth!

I have one particular stain on one of my teeth and have found that this is the only toothpaste that effectively polishes it away! But as soon as I discontinue use and switch to another brand, it reappears. I wish I could get rid of it permanently, but this toothpaste is fairly inexpensive so I don't mind buying it as my regular brand.

Inlovedvthe taste of this tooth paste and it also made my teeth feel so smooth. Noticed that my breath stayed fresh feeling for a long time also. My teeth seemed to be brighter after a few uses

I really enjoyed using this toothpaste! I found the taste to not be super overbearing, and there was no grittiness like with some other whitening toothpastes. I thought it really cleaned my teeth well; perfect amount of everything.

I can't say if it's a good product of not about effectiveness: bought a tube for trying it, it opened by himself in the cabinet and destroy the part of the shelves the tube was one. Not impress at all by the quality of the material at all!!
