hi, im in the uk, just be careful of some holistic dentists,my dentist was supposed to be holistic but only used a dam, nothing else and that was at my request, an extra £40.00 per filling. i would go into harley street, london, and pay for all protection.
you can buy those cacoa nibs in Revital, a health food shop around the uk, i didnt know they detox mercury, but they are recommended.
