Sealant Saturday is back in York County again for Children's Dental Health Month.

Free dental examinations and dental sealants will be provided for children age 6 through 16 on Saturday at the York County School of Technology, 2179 S. Queen St.

No appointments are necessary, and senior dental hygiene students, registered dental hygienists and local dentists will be serving children from 9 a.m. until 1 p.m.

Take-home kits: Hygienists will give free oral hygiene instructions and home care kits to all children in attendance.

"They will be offering activities that teach the kids how to take care of their teeth and the importance of routine dental care," said Julie Polito, one of the event organizers for York County.

Sealants are made of a thin bonded material that helps to prevent tooth decay, but they will not be placed on teeth that already have cavities, the release said.

"It is a great preventative measure to prevent cavities from forming in the back teeth," Polito said. "It helps reduce the rate of decay."

Sealants last between five and 10 years, are half the cost of a filling and require no injections or anesthesia.

"It's meant for the ones who don't have insurance or are underinsured, but we won't turn anyone away," said Polito.

The program: Sealant Saturday is sponsored by the Pennsylvania Dental Hygienists' Association and Dentsply Professional of York.

About 580 children were treated on Sealant Saturday in Pennsylvania in 2012, and approximately 30 percent of those children had open, visible, untreated cavities, the release said.

If cavities are found during the exam, the patient's parent or guardian is informed and is given information about where to access care for their needs, Polito said.

This year, 23 dental hygiene educational and community health clinics will provide free dental exams for children in Pennsylvania.
