Baking Soda (Sodium Bicarbonate) is The Best natural mineral for teeth whitening IMO. Some people confuse baking soda with baking powder, they are two separate things. Baking powder should not be used on teeth, because it has acid. Baking soda is purely basic and safe. I'll post some recipes later (I.A)
P.S. Most Arm and Hammer toothpastes have baking soda in it.
