I was recently at the dentist, and I was curious about the about the music they played, in the different rooms for the various patients. I was told that the music choice was based on what the patient had being done to their teeth. She explained that if it was just a cleaning, they would play clean music with wholesome lyrics.

So I asked, “What if the patient was getting braces?”

“Considering what the braces are made,” she responded. “We’d play heavy metal.”
