The central Appalachian states lead the nation in toothlessness. More than 32 percent of Tennessee residents surveyed last year had lost six or more teeth because of decay or gum disease, according to the Centers for Disease Control. That number was 38 percent in Kentucky and 43 percent in West Virginia, which holds the distinction of the most toothless state. Kentucky ranked No. 1 in toothlessness in 2003.
