Mythbusters Wiki
  • The Myth - It is possible to pick up radio signals through a dental filling.
  • The Verdict - It is possible.
  • Notes - The gold and amalgam tooth fillings did not act as an antenna or point-contact transistor when placed in a real human skull. Explanations for the supposed Morse code pickup included a Galvanic cell reaction between two teeth fillings and saliva. However, empirical evidence has shown this to be possible with silver fillings.
    • This was first claimed by Lucille Ball in an interview on The Dick Cavett Show, with the fillings explanation offered by Buster Keaton.[1]
