Hi Dr Pizzorno, live in England and am coming to see you when you come to London. I have at least 10 very large amalgam fillings ( my mum sent us to the dental hospital as kids so they were done by students), one of the filled teeth has now cracked so a large portion is up against my cheek. I am wondering do you have an opinion what is the best, safest alternative. I have Crigler Najjar Type 2 and am 50 years old. I have generally had good health but think cleaning up my mouth would be a good thing to do but am concerned removal could stress my liver or the rest of me.
