I know the subject was discussed but I can't find it.
Rooting (oops sorry that's English slang, I mean nosing :)) around old message I found a link to a natural tooth care dentist's site. From there I found another good site with this information about remineralization
I am continuing to pull with sesame oil inc a couple of drops of oil of thyme and some heavily diluted sage oil from capsules (do not dilute your own!) Oregano is no longer easily available here as my health food store says there was an issue with aromatherapy oils (not pharmacutical grade) being used for cancer therapy and they didn't want to get sued.
I have move also to bicarbonate of soda and Sea Salt mixed with Colloidal Silver (not hydrogen peroxide as I still have a mouthful of Mercury) for teeth and gum cleaning to avoid toothpaste bases.
Once my gums are in reasonable shape I will be going back to my dentist and see if his views have changed on mercury removal. Previously he did not want to do it because of the risk to his and his staff's health but was willing to back me going to another dentist he recommended.
