Hello Doctor, my silver fillings are replaced by tooth coloured composites. I was not having any pain when I was having silver filling, but one of the doctor told me to replace it when I was having treatment of bridge crown for other side. But now I am getting constant pain to all the replaced fillings. And it has become very sensitive can not use normal cold water.one of the doctor told that it is the allergy of white composition. What can cause this pain? What can be the treatment for this?
