Hmmm no.
Whilst colgate is a great toothpaste, I didn't see any changes in the colour of my teeth.
My teeth looked lovely and polished and shiny however no noticable change.
The taste is pleasant and the 'fights germs for 12 hours after' is awesome.
But it's just not a good whitening paste.
Especially if you're a tea lover.
I have so much trouble with my teeth and finding a toothpaste that whitens is like next to impossible. I've brought this a few times when it's been on special to give it chance after chance but no success.
It is a great toothpaste for making your teeth feel fresh and clean, you really do feel a difference in how clean they feel, when using this toothpaste my teeth felt significantly stronger, it didn't give me any sensitivity issues compared to other whitening toothpastes.
My issues with this toothpaste was I didn't notice any difference in the colour of my teeth, they stayed the same colour from when I started using the toothpaste down to the last drop, the second problem is the after taste, it tastes like a chemically strong taste, i didn't like it at all.
I score this 3/5, it cleans your teeth very well and doesn't make them sensitive but it doesn't whiten and the after taste is too strong for me.
