Not long ago I was in the chair at the Dentist office with the doc and a few of his female attendants. I asked him about tongue hardware. He said he gets lots of business because of it. Seems most people move their tongue around when they sleep, which removes most of the enamel on the insides of their teeth. One of the ladies asked, "And what’s the point of it anyway?" To which i laughingly replied, "There is only that one reason for it." To which I got blanks stares from them all. Down here in Dumbutt, Texas.
