i dont think my dentist offers porcelain only composite. i dont dispute what youre saying but how many people have health problems due to compositie fillings? never heard that before. im not disputing they are toxic, but to what extent?
i did ask the other day in a different post whether i should try and heal the cavities naturally (i dont know if its even obtainable) or go for composites, didnt get any replies on that one though.
