Or maybe "Our dentists are being poisoned!"  I looked into a gold tooth when I had to get a filling because I didn't want the mercury but it would have been like $500-600 extra, hopefully an inexpensive and better solution can be found. Given the choice between getting a filling and having a slight mercury exposure and death from tooth decay if you don't get a filling though one imagines over the last 150 years amalgams have saved billions of lives.
