Walking antenna, metallic fillings and Lucille Ball.

An important consideration in this case is whether or not the music heard by your mother-in-law coincides with broadcasts on local radio stations. If she can match what she hears to radio programs on the air at the same time, it is possible that her crowned teeth are acting as antennae that is, if the crowns are metallic.

The most famous example of this phenomenon was reported by Lucille Ball in 1942. Lucy had several fillings installed in her teeth around the time she was filming ''Du Barry Was a Lady'' with Red Skelton and Gene Kelly. During the drive home from MGM Studios to her Desilu ranch in the San Fernando Valley, Lucy received radio broadcasts of music through her fillings. She reported the incident to actor Buster Keaton who told her the same thing had happened to a friend of his. A week later, Lucy drove a different route from MGM to the ranch. This time her fillings vibrated with short beeps (DE-DE-DE DE-DE-DE) that sounded like Morse Code. She reported this to the FBI who then searched the area in Coldwater Canyon where she heard the beeps.

FBI agents eventually found a radio transmitter hidden in a tool shed that was used by a Japanese gardener. Later it was determined that the gardener was a member of a spy ring operating on the west coast. So the story goes, anyway.1

Other reports exist of radio broadcasts being received through dental fillings2-3 and even through shrapnel fragments embedded in the skull of a Vietnam veteran.4

If your mother-in-laws perceptions do not coincide with broadcasts on radio stations, we must conclude that they are auditory hallucinations. The perception of auditory hallucinations does not necessarily mean that your mother-in-law is ''crazy.'' Schizophrenics and people suffering from other psychoses or dementia often experience phantom auditory perceptions. Because you wrote that your mother-in-law ''has been told that she's very healthy and nothing is wrong,'' we will rule out psychosis and dementia as possible etiologies for her hallucinations.

It is possible that anesthetic or analgesic medications used during or after the dental procedure caused changes to occur within her auditory system and/or central nervous system. Musical hallucinations have been induced by aspirin5, alcohol6, triazolam7 and propranolol.8 Of course, recreational drugs such as L.S.D., mescalin, marijuana and others have also been known to evoke auditory hallucinations for some users.

In their reviews of the subject, Berrios9 and Gordon10 concluded the following about musical hallucinations: they are usually associated with some degree of hearing loss; they are more common among women (70-80% of the cases); they occur more often among older people (average age = 60-70 years); they are sometimes associated with brain lesions or psychiatric disorders.

Musical hallucinations have been reported by some patients suffering from depression.11-12 In these cases, antidepressant medications can sometimes reduce or eliminate the hallucinations. Antipsychotic medications, anticonvulsants, and anxiolytics have also reduced auditory hallucinations experienced by some patients.9,13
