Colgate Optic White Toothpaste review

I'm very skeptical about products claiming to whiten, often a lot of hype with no results! I was eager to see if Colgate could deliver what it promises. I have some discolouration of my teeth, particularly the bottom ones. I used the toothpaste daily for over a month and I have noticed some lightening of those teeth, not so much the top. I didn't enjoy the taste (was slightly chemical tasting) but the feeling after brushing was fresh! I would buy again!

It brought on sensitivity which I've never had before!! Didn't notice any change since I wasn't going to let it make my sensitivity worse :( was such a fail

I like this toothpaste, after using it my teeth feel super clean and I also like that different texture it has. Although I haven't noticed a difference in the colour of my teeth. But I would definitely use it again

I've tried other whitening treatments and had sensitivity and little/no results. This is actually very good! I definitely noticed a difference in a month, not Hollywood white, but definitely whiter, and I didn't have any problems with sensitivity. It tastes different from normal toothpaste, but I got used to that quickly, and as a bonus it somehow makes my teeth feel cleaner.

After seeing the adds for this on tv I was a bit skeptical, but ive been using it for a while now and even my husband has noticed a change in my smile!! Its not something that happened straight away but maybe 3 weeks later I started noticing a whiter appearance to my teeth. Great product. Something we will keep using in our house

I tried this toothpaste, it did not whitening my teeth by three shades all, did I not notice a difference at all really. Only good thing was that it does leave your mouth feeling fresh. Probably wouldn't use it again.

I didn't notice much difference with this one, it was nice and gave me a fresh feeling mouth but didn't stand out from any other whitening toothpaste. Probably wouldn't use again as noticed more difference from a cheaper brand used before.

I have tried a variety of different whitening tooth pastes but this is the first product I have used that I have actually noticed a difference with. I'm not sure how to judge the "three shades" but my teeth are definately whiter. It tastes strange at first but now I prefer the taste to normal toothpastes - it seems less sweet...

It lighten my teeth slightly but hardly noticeable after 4 wks of using it. It can be very strong and stingy.
