@Shiroyasha it's ~2 on mohs hardness scale. i'd say that's ok, given that even dentin is harder according to wikipedia.
@Shiroyasha i'm not a dentist though, here are my "sources". do you have a recipe for your toothpaste or did you just eyeball it? might want to try it :)
> 10.5.3 Sodium bicarbonate
Adapted for the aerospace industry in the mid 1990s, bicarbonate of soda also known as sodium bicarbonate is a pure mineral with a relatively soft hardness of 2.0 on Moh’s scale. Propelled at 2–6 bar (30–90 psi) it can be used in either dry or wet modes.

@Shiroyasha thanks, will try it, i have most stuff here already :)
be careful with other mineral supplements, those might easily be harder! probably more useful to just eat them ;)
