The sale of gold is regulated, so those who melt it down for use in false teeth are not able to get licenses and continue to be part of the black market. The tooth maker charges up to $40 per tooth, including installation, using gold melted down from jewelry and trinkets he buys from secret suppliers.  (ASSOCIATED PRESS)
