The mercury seeps out over the life of the filling. 10-20 years. Even at the end of life there is quite suffiecient mercury to keep it up. They wear out and fall out or break before they run out of mercury. And as I said, it isn't like your body excretes the mercury the next day. It can hang around for years and decades. And accumulate.

I believe it varies from school to school. Dentists are still in denial. They don't have a good material to replace it.
