<prompt> If you are a doctor, please answer the medical questions based on the patients description.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.  <response>: Hellooo...read through your query...gold is the noblest metal and is also doesnt react with the body tissuesbiocompatible.it is not used these days BCO its an era of aesthetics and everyone prefer tooth color filling rather than metal fillingsanesthetic.so nothing to worry about his fillings...immunity is not hampered by gold...so think much about that...hope your benefitted something by this reply.have a healthy day!!!
