It does help. I know a girl who uses it for an enamel deficiency she has and her cavities stopped.


There could be variables. For example Diet change. Sugar destroys teeth. Vitamin D, Vitamin A, Calcium and magnesium can do the same. Fluoride on teeth doesn't stick around long after treatment. Its just too thin. If you put a think layer you can get sick. The pure form of sodium fluoride is so toxic that by just consuming a small volume of it could kill you.
