Once-homeless man starts over with free "million-dollar smile" from dentist

Harvor Davis was standing in line behind hundreds of homeless people waiting for his turn to get food when he noticed a man with a huge smile on his face.

He turned to a friend and asked, "Who is that?"

Davis was surprised to find out the man, who appears as if he was just like everybody else, was actually the executive director of the nonprofit SoupMobile -- a food service that brings http://www.hlaac.com/how-to-choose-the-right-dentist/ food to the homeless in the Dallas area.

With a nervous grin and a mumble, Davis asked David Timothy if he could volunteer.
