> Are they still using mercury in fillings?

Absolutely.

Over 1,000,000 mercury-amalgam dental fillings are placed every 3
business days in the United States.

Many people are not aware that tattoos, particularly the red inks, also
contain a considerable amount of mercury.

Other sources include many vaccines, including this year's "flu" shot,
and coal-burning power plants.

Our local coal-burning power plant in Jamestown, New York spews 720
pounds of mercury into the air each year. Considering that less than
one gram of mercury is enough to declare a 25 acre lake contaminated,
this is a massive amount.
