Yep, going through the same pain as you are. I had one amalgam drilled and replaced with the material I am least resistant to. At first the tooth was so sensitive that I would not chew on the whole side. Now it got better but still I am like you sensitive to cold, hot, pain is in the upper teeth where no drilling was done, sometimes a toothache occurs and then all I can do is to wish for it to go away. I do not think that it has to do with the replacement material. My speculation is that it's from mercury being redistributed all over your mouth after the drilling. Mercury loves tissue, so it probable is holding strong onto the mouth tissues. I remember that after the drilling, the doctor had to take an x-ray to see if there were any mercury left, and during that time I could not control my mouth from twitching in a similar manner as an eye twitch. So lets cross our fingers and hope that once we chelate, the pain will go away. <img src="/ubbthreads/images/graemlins/smirk.gif" alt="" />
