Another hero of the mountains is Dr. Edwin Smith of Barbourville, Ky. He used $150,000 of his own money to convert a truck into a mobile dental office. Dentists say Central Appalachia is first in the country for toothlessness. One of out 10 residents is completely without teeth and children as young as 2 already have as many as 12 cavities.
"A Hidden America: Children of the Mountains" is a continuation of Diane Sawyer's reporting on America's forgotten children. Sawyer won an Emmy for outstanding feature story in a news magazine for "Waiting on the World to Change," a firsthand account of poverty among children in America, which aired in 2007. The yearlong reporting followed the lives of children in one of the poorest cities in America who struggle daily to succeed despite horrendous odds.
