Dental Hygienist Liaison Project

Because of the importance of oral health during pregnancy and early childhood, in 2011 the National Center on Health, working in partnership with the American Dental Hygienists' Association (ADHA), created the Dental Hygienist Liaison (DHL) project. Under the DHL project, one dental hygienist from each state volunteers to help promote oral health for pregnant women and children enrolled in Head Start. The DHL project continues as part of the Office of Head Start currently funded through the National Center on Health, Behavioral Health, and Safety (NCHBHS). The National Maternal and Child Oral Health Resource Center is the project lead for NCHBHS oral health activities and works in partnership with ASTDD, which coordinates the Dental Hygienist Liaison Project.

Role of the Dental Hygienist Liaison

DHLs promote oral health in Head Start by:

  • Providing a communication link between NCHBHS and Head Start agencies in their states
  • Collaborating with state organizations such as oral health programs, Head Start collaboration offices, and Head Start Associations
  • Providing oral health presentations at state conferences and meetings
  • Offering strategies to improve access to oral health care for pregnant women and children enrolled in Head Start
  • Working with oral health professionals to establish partnerships with local Head Start programs
  • Sharing information about the importance of oral health and regular oral health visits, good nutrition and oral hygiene practices, and oral-injury-prevention strategies with Head Start program staff
  • Serving on Head Start committees (e.g., Head Start health manager networks, Head Start health services advisory committees) and oral health advisory boards and coalitions to promote the oral health of Head Start participants

DHLs also share stories of their successes and ask for suggestions from the group. (September 2022)
