But still I expected better from a toothpaste 15 I is not more effective than ordinary toothpaste on me anyway.
I got much better results with the colgate max white optic which slightly bleached to me.
But he did nothing at all, it is effective, the teeth are clean and toothpaste has a pleasant taste, but I get a similar result with a more conventional toothpaste. Only the failure to rinse the toothpaste after use change others, but that's all.
Perhaps is it effective on people who have white teeth at the base but stained by coffee and tobacco ...
