wikipedia mentions cobalt-chromium and nickel-chrome alloy fillings. I'm assuming they're not magnetic, but maybe an extremely powerful electromagnet could attract them?
Well apparently cobalt and nickel are magnetic, however in some alloys they may not be. I was unaware that any of those metals were used in dental fillings. The most common metal is silver.

Edit to ADD: I guess actually most common is amalgam which is a composite of mercury and silver, although copper and tin can be used.

Interesting. (who says watching TV can't be educational? )
