Dear Hao, I recently got Dr. Mom's video collection and book from MH-- and Dr. Mom, in her book mentions using a similar Dr. Christopher's based formula on her family's broken bones. I beleive it was the Bone's & Cartiledge formula, and I think it might be mostly the same ingredients as Barefoot Herbalist's tooth powder.
Those in her family that ate it as well as applied it topically found that their bones restored-- to the doctor's disbelief. Even her elderly mother had bone restoration! There is alot of things medical science refuses to accept, but decades later they may be forced to accept about how the body can heal itself if given the proper care.
I believe that Barefoot Herbalist's tooth powder might just restore the mineral balance in that tooth and permit it to fuse back. You will also have to eat mineral rich plants as well and maybe make the toothpowder into a paste and glob it that tooth everynight. If you are afraid to chew with that tooth, you could juice them and therefore be better able and more quickly absorb the minerals into your body.
MH, is this right ? Im lookng foreward to more info MH has on this
