Smith invested $150,000 of his own money to build a mobile dental clinic, Kids First Dental Care, inside an 18-wheel truck. Several days a week, Smith criss-crosses the curvy roads of 16 eastern Kentucky counties to offer
free dental screenings and services to hundreds of students. Most children dread the dentist, but those who line up outside Smith's van are often giddy with anticipation. For many, it's the first and only dental check-up they'll have for years.
