MAYNARDVILLE, Tenn. (WVLT) -- Hours in line and into dentist's chair for Robert Sumlin. Sumlin is one of about 440 people who hoped for healing at the Remote Area Medical Clinic at Union County High School.

"We left about 5:30 in the morning," says Sumlin of Erwin, Tenn. He drove his wife and son to Maynardville in hopes of a little help for his tooth tenderness - by getting two pulled.

"I need more, but I'm just going to get two because I need to go back to work Sunday night. I can't afford to lose my job," says Sumlin. One of nearly 500 facing unfortunate circumstances, that's where Remote Area Medical steps in.

"Some 250 wanted to see the eye doctor and get a pair of glasses, 350 wanted to see a dentist and 50 or 60 wanted to see the general medical doctor as well," says RAM Founder Stan Brock.

RAM has enlisted 45 thousand volunteers in its two-decade long effort to heal the uninsured or under-insured. Brock says he'll continue, but called on national leaders to find a health care solution to help.

"What they do need to be doing is taking care of the 47 million odd people that don't have access to the system as evidenced by the huge numbers of people we see," says Brock. "But it has to include dentistry and vision and not just primary health care."

Volunteers say the smiles they receive are worth the travel and effort. "They are very grateful and that's the most rewarding part about it," says Jessica Marinoff, a dental student at the University of Pennsylvania.

Sumlin says he agrees. "Get your teeth fixed they do a good thing. People that can't afford it, they do a good thing," says Sumlin.

If you need care, Remote Area Medical will be back at Union County High School Sunday. The address is 150 Main Street, Maynardville. The parking lot will open at midnight. Queue numbers will be passed out at 3:30 in the morning. If you want a number, organizers say be there early. Care begins at 6 a.m.
