The Missouri Oral Health Preventive Services Program (PSP) uses a community-based approach to prevent oral disease through annual screenings conducted by dentists or hygienists, educational materials, applying fluoride varnish twice per year to children's teeth, and referring children in need of dental care. The program involves screeners, varnish volunteers, event coordinators, and support from the Missouri Department of Health and Senior Services. The program aims to address dental caries which impacts many Missouri children, especially those from lower-income families and racial minority groups who often lack access to dental care.
