GREENSBORO, N.C. - Even though registration didn't begin until 6 a.m. Friday, the line for one of the Piedmont's largest free dental clinics began forming the night before.

The North Carolina Dental Society and North Carolina Missions of Mercy are hosting the clinic, which runs Friday and Saturday at First Presbyterian Church.

Volunteer dentists, hygienists and dental assistants provide extractions, fillings and cleanings to hundreds of people in need. By the time the clinic is over, organizers estimate they will have provided $300,000 to $400,000 worth of free dental services.

"This is something good for people. A lot of people can't afford dental. I mean, I can't. It's a good thing for people who can't afford it," said Kenneth Gregory, who arrived Friday to have his teeth looked at.

Organizers say the clinic is the largest the dental society holds in the Piedmont. The services are only for adults and no appointments will be made.

Those who want help should expect to wait in a long line.

All services are provided on a first come, first served basis, but organizers say they're really for people with incomes below the poverty level. Still, they'll help anyone in need.

"For college student like me, it's kind of like, you can't afford to get health insurance and I'm just grateful for the opportunity because it helps people like me be able to get stuff done," said Jamee McPhaul.

Registration for the Saturday clinic begins at 6 a.m. at First Presbyterian on North Elm St. The clinic runs from 7:30 a.m. to 3 p.m.
