Use this powder for 2 weeks now and it really helps!
Our teeth are getting whiter and my husband has the smoke deposits disappear from his teeth.
If you use it, you have black teeth, this looks pretty heavy. After use, rinse and brush your mouth with regular toothpaste.
It is recommended to use this twice a day.
It doesn't taste wrong, there's a minty flavor in it.
Your tongue does not discolour and you will also clean your toothbrush after use.
I am very satisfied!
