My husband and I wanted to give this a go. Whiter teeth would be lovely.
The tube is small for the price. I like the colour of it. Nice and bright. The texture is like a Normal paste. I did wonder if it would be slightly different to help make teeth whiter. Taste is ok. I like ones that make teeth feel cleaner for hours. This doesn't do that. We ended up buying this a few times in a row thinking the longer we used it, the whiter our teeth would be. This isn't the case at all. We don't smoke. He doesn't drink hot drinks at all. Neither of us seen any difference in colour. I have just resorted back to another brand.
I had been wanting to try this for a while before I had brought it due to those ads with the girl in different outfits brushing her teeth. When I finally got round to buying it I wish I got it sooner as my teeth felt so clean. I feel like I won't be changing toothpaste anytime soon. everytime I have to use someone else's it just tastes like the weak kids products. The optic white has whitened my teeth and makes them feel properly cleaned.
Tips: Use a Colgate brush, the three 360 is my favourite
