I thought I'd wait at least 6 months of using this toothpaste before I did the review to allow it time to get to work. Well I've waited long enough and I can conclude that this does reduce the sensitivity your teeth feel when drinking hot or cold drinks, but it has done absolutely nothing for the whiteness of my teeth.
However I did kind of expect that as my teeth are quite yellow when compared to others. I'm not sure why as I have never smoked or anything like that which could have impacted them. This might work on somebody with whiter teeth than mine, but if it's just gentle whitening then they probably won't notice either, so I don't really know what the point of selling it as a gentle whitening toothpaste is?
It does taste good and comes in a nice dispensing bottle and it's very cheap if you can manage to get it under £3.00 every time, which I have managed to do so far. So I would still give this 4 stars, and take away just the one star for it not performing on the whitening side of things.
