Most people don't realize that their fillings can be highly dangerous to their overall health. We have decapitated the patient and forgot that what we place in a person's mouth has a direct effect on their immune system via the meridian pathways. If someone has a silver filling, that person's body is burdened by the mercury content in those fillings. If they have a porcelain crown, they might have a nickel-based metal. Mercury and nickel are the heaviest metals on this planet-and mercury is the most toxic.That being said,we are adding another burden to our bodies which already have to deal with so many other burdens like diet, environmental pollutions, and stress!!
