Why don't blueberries stain your teeth?!


Question: Why don't blueberries stain your teeth!?
Whenever I eat blueberries (I have been eating a lot lately) my hands get stained rather quickly and if I mistakenly drop one (like I did on my pants- stained) so why not on my pearly-whites!?

Explanation please!.Www@Answer-Health@Com

Answers:
enamel of teeth is porous (no microscopic spaces in it),so stains can not be precipitated on it easily,this is fortunately good,as if u drop a stain on a marble or glass compared to a piece of clothesWww@Answer-Health@Com
Maybe teeth are waterproof!.
Waterproof means that water cannot get through the object!.
