[BC] AM detection in teeth/fillings

[Paul Smith W4KNX]

Back in the late 60's the first radio station I worked at you could hear the
station in the boundary fence when there was fog.  Kinda sounded like they
sound when you hear the station in the coils in the tuning house.  I once
took a call from a person here locally that they could hear a station in
their toaster on their kitchen counter.  It was true.  Went out to look at
it and sure enough, if you position the toaster just right, you could hear
it.  The house was about 1/4 mile away in the main lobe.  On a foggy day,
you can hear the sync buzz from a local TV in almost everything.  In all
cases, it was rectification at a loose or corroded connection somewhere.

I agreed to speak 10 minutes to to a senior club of about
200 next Tuesday.

They want a shirt sleeve explanation of how radio works, but
  specifically asked me to tell what is known (truth or
fiction) about people reporting that they "hear" radio when
living near big AM stations.

I think it is this the phenomenon whereby the dental amalgam
metal is acting like a crystal in teeth?

Are the teeth then making a vibration producing audio, or is
it a nerve transfer of the detected audio into other nerves,
mimicking sound?

Anyone who can refer me to an explanation, Thanks!
