My 53 year old son has 7 gold capped teeth. I had several murcury fillings in the past , of which I experienced a unpleasant time each time when Iwpould be using a silver-plated fork or spoon into my mouth. My son has developed an incurable disease, Scleroderma. A autoimmune problem. There is little known about Scleroderma. I know I am clutching at straws. With that much gold in his mouth causes me to wonder. I know that gold does react differently than the old murcury, but I am wondering if all that gold is causing some sort of reaction to his immune system.
