Surely there must be a blues song concerning dentists?

There are plenty with lines about, "I went to see my doctor..." and the doctor tells the guy he's got the blues, or is in love, or needs jug band music to cure what ails him, or needs a mojo, or has a boy-child coming who's gonna be a sonavagun....

How about, "I went to see my dentist..."

"and he told me, son, you need a woman named Flossy," or "you got a brush with greatness comin'," or " you need to wash your mouth out with soap..."

Time for the first cup of coffee of the day ; > )
