In theory this sounds good. 3 shades whiter teeth? Yes please!
I love the metallic red tube this comes in it looks pretty and makes me want to use it. I love the real minty flavour of this it's quite strong and reminds me of the imperial mints. It leaves my teeth feeling very clean for hours afterwards better than any other toothpaste I have used. But I will unfortunately never use it again. It has left my teeth and gums so sensitive nearly every tooth has been aching and my gums have felt like they are burning. It's really thrown me because I hardly ever get sensitive teeth generally only if I eat ice cream too fast. I think it could be the hydrogen peroxide that's causing the sensitivity because I have never experienced this before with normal toothpaste. Never ever again! I will leave the whitening to the dentist.
