Do whitening toothpastes work ? They advertise whiter teeth within days . I have been using it for months and notice no difference. The tooth, beside the porcelin crown tooth, does not get as white as that one. Why are they allowed to advertise whiter teeth if it stays the same ?

Waste of money. Thy can get away with it because the toothpastes will generally remove some superficial stains, but then most toothpastes can do that too. They have no bleaching ingredients. Good old marketing ploy, just like every year there's a new toothpaste, a new toothbrush style, ...

Just as I thought but why does it say on the box to not use it for more than one month ?

No idea. probably to make you think that it has some sort of efficacy that is dangerous if "overused". I've never seen anything in the literature that mentions that requirement. It's similar to a lot of alternative medicines where they tell you strict dosages, despite inactive ingredients - you're more likely to get a sugar hit than an overdose.
