I definitely saw an improvement in the colour of my teeth after 2-3 weeks of using this toothpaste 2 times a day at the least. My teeth were not stained beforehand and were already pretty white, so I didn't expect to see dramatic results, but I definitely noticed that my teeth seemed slightly whiter and shinier after a few weeks.
I like the taste of this toothpaste, and it feels like its getting the job done.. Not like those clear blue/green toothpastes that taste like sugar.
Would definitely buy it again simply as a toothpaste to maintain my current colour as I feel it has some whitening properties but not enough ti justify buying it JUST to whiten my teeth.
I love this toothpaste, it helps me get white teeth without having to get it done professionally. Sometimes teeth whitening treatments done professionally can make your teeth weak and porous, so I always prefer using whitening toothpastes, hence it saves a lot of money too. The toothpaste is slightly thinner than the other toothpastes, it has a very refreshing minty flavour, leaves my teeth clean. After several uses I notice my teeth look much whiter, to maintain the whiteness I have to continue to use it. I only buy this when it is on special. A very good toothpaste.
