thx for your response. i just emailed the dentist asking what materials he used. i really didn't want to talk to him. i've suffered from this nervousness for 4 months. i was so happy when all the metal was removed, my health improved so much, and now i feel just as bad as when i had them all in my mouth. i hope to find an answer to all of this <img src="/ubbthreads/images/graemlins/frown.gif" alt="" />
