Anuja,
I would love to see what you find out about fluoride. As often happens, a statement on this board sent me off to research as well so I've been reading a bit on fluoride and platelets. The medical research I found is so dense I haven't been able to make much sense of it.
Another possible consideration with toothpaste is the artificial sweeteners such as sorbitol and xylitol. Especially in young children who might be swallowing more than they are spitting. Some people (myself included) get some bad gut reactions to the '-tol' sweeteners, which can lead to inflammation which can exacerbate some platelet problems.
