To Heal a Cavity:
1. Ditch your toothpaste that contains glycerin (prevents remineralisation of teeth), which is everything you can find in ANY store, with the exception of Eco-Dent or other brand tooth powders, which still has silica (abrasive). I'm still using it but thinking of switching to colostrum tooth powder.
2. Start taking fermented cod liver oil and high vitamin butter oil (vitamin K) (Weston A. Price discovered these little gems) and eat grass fed raw butter if available.
3. Watch the magic.
