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

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

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.

BUT, Buyer Beware. If you are like me I have never read the warnings on the back of the box or tube. It says to Not use longer than 6 weeks unless advised by Dentist. Who would have known??
Toothpaste really works but am very weary about using longer than advised, so have switched to other toothpaste for awhile.

As a smoker & heavy coffee drinker, it is really important to me to have a really effective whitening toothpaste. Colgate Optic costs less than the others and is just as effective. My teeth stay whiter than with regular, non-whitening toothpastes (and even some whitening brands).

J'ai remarqué une bonne différence avec ce dentifrice: les dents blanchissent vraiment ! Je n'avais pas vraiment les dents jaunies au départ mais j'ai remarqué plus d'éclat !

I love using Colgate optic white tooth paste. It always leaves my mouth feeling fresh and clean. It helps keep my teeth nice and white.

I have used this before and then switched to another tube of toothpaste recently i started using Crest optic white again and there is a noticeable difference in the whiteness and brightness of my teeth.
