I am on the board of the National Children's Oral Health Foundation. It is a group dedicated to getting proper dental care for children who are less fortunate. The Foundation started in 2006 and has formed a network of dental providers, non-profits and others interested in improving the overall health of children nationwide. It has started work in developing nations as well.
Contact them to learn more and to find out how you can help. Also, call your dentist's office to find out if they are involved. If you don't have a dentist, call 1-800-DENTIST today.
