Dear Dr. Kannan,
You may find it interesting to read some data collected by a Swiss dentist, pertaining to his own patients and their medical symptoms before and after removal of amalgam fillings. He appears to have the inquiring mind of a scientist, was aware of the controversy regarding amalgam, and became curious to see what could be understood from those in his own practice.
His report, available in German, English and French, can be found at

A few other websites that mention some of the symptoms that can arise from the presence of mercury dental amalgam are listed below. If it would be helpful to have more, I would be happy to suggest additional ones.
