This is very good. it leaves my mouth feeling clean and fresh. don't know about the whitening but it's a great tooth paste.

It really works!!! Since I've been doing the whole process of using toothpaste, flossing and using mouthwash, my teeth look whiter. I'm sure is the toothpaste. My test are white by themselves, I'm guessing the way I was brought up and the food I was eating as a child, but now they are whiter...love it!!!

all I can say is it defiantly whitened my teeth after the first use. it is my regular brand!

I have found this product to be everything that it was advertised to be. Extremely happy with it!

I've been using this product for about 2 years. There is an improvement in the whiteness of my teeth. Leaves my mouth fresh and teeth feel clean. It's the only toothpaste I will use now!

This is the BEST whiting toothpaste! Hands down!
I drink at least 5 cups of coffee a day and I used to smoke ( quit 8 months now YAY) and I must say Optic Whilte by Colgate works. My teeth were obviously whiter that even I noticed it. All my friends asked what I was using !
amazing if you want whiter teeth

Due to allergies I am always nervous trying new items. Thankfully I didn't react and love this product; nice mint flavour!

The best toothpaste I've tried yet ... a bit more expensive, but oh so worth it !

Used for tow months, not really any improvement seen. It is quite a bit more expensive than average toothpaste. You can buy it anywhere though.

Love this toothpaste. I've tried a few other brands and just don't see the results I do when I use this one. Really effective and easy way to keep teeth brighter and stain free. Doesn't make your teeth sensitive.
