Q. Hi I am a thirty year old woman and feel my health is being compromised by my amalgam fillings. I recently broke one chewing on a toffee bar and after having it patched, literaly weeks after I developed a sinus cold which developed into a secondary chest infection. I have developed many symptoms in the last few years including asthma and hayfever and I now believe I am allergic to mercury as my doctor has no explanation for my reoccuring illnesses. How do I broach this subject with my dentist? Kind Regards
