We had used Sensodyne before, but wanted to try Colgate Optic White. OMG! The results are amazing. We are coffee drinkers and our teeth are 10x whiter than before.

I've enjoyed using COW toothpaste it gives my teeth a clean feeling, and white teeth. Great product

Great Whitening Toothpaste

Alright, Colgate Optic White Platinum, let's talk. I brush three times a day, and my teeth are still auditioning for Fifty Shades of Yellow. This toothpaste promises whiter teeth, but it’s more like the friend who always says, “I got you,” and then forgets to show up. Four stars because, hey, my breath is fresh – even if my teeth still look like they're stuck in the 'before' picture.

I don’t notice a difference in the whiteness of my teeth, it leaves a slightly chemically taste in your mouth after use.. I figure it’s whatever they use for the whitener they add to it, perhaps? I took a star off for that, but it was a good price for 4 packs. It’ll last while.

Not the taste we expected. But is an effective whitener. It has an after taste we do not like.

my teeth are no whiter than if i used regular toothpaste

i was disappointed with this compared to my last brand Polident because of the taste. It left a sharp tingling feeling in my mouth.

I have not been able to see a difference in my teeth. I have been using the product for a month -2 months. Bummer.

Colgate changed the size (only 2/3 the usual size) at a much higher price. Please bring back the traditional toothpaste.
