We just looked it up, and found this description on the website:
National Children’s Oral Health Foundation: America’s ToothFairy (NCOHF) is dedicated to eliminating children’s preventable suffering from pediatric dental disease by providing programs and comprehensive resources to deliver community-based critical preventive, educational and treatment services.
There is lots of information about how you can get involved, too!
