I don't know whether its the minty freshness or the hint at whitening that always draws me back to purchasing this toothpaste. I am a huge fan of Colgate toothpaste and often have one of these in my trolley.
I have to say that I didn't notice any difference in the whiteness of my teeth but I do love that they have more than one size available.
But on the up side it leaves my teeth fur free and my breathe minty fresh. There is a tad after taste but that doesn't bother me.
I've used this toothpaste for many years, I can't remember not using it to be honest. I do believe it's one of the best toothpastes on the market, as I have managed to go 23 years without any fillings, but I do not feel like it has any whitening agents. Definitely refreshing after use, pleasant, soft, minty flavour.
Tips: If you want your teeth whitened, you may have to actually buy whitener, instead of using a toothpaste.
