The N.C. Dental Society is holding a free clinic for needy adults, March 12 and 13 at the National Guard Armory.

"We have an awesome opportunity," said public-health Director Gayle Harris.

The clinic provides teeth cleaning, fillings and pullings on a first-come, first-served basis for patients whose family income is less than 200 percent of the federal poverty index: $44,100 per year for a family of four, for example. (For a chart, see http://liheap.ncat.org/profiles/pov.)
