The municipality of Nanterre in the Hauts-de-Seine department has adopted an early childhood policy aimed at reducing inequality. Half of Nanterre’s residents live in working-class neighborhoods. The health department has prioritized expanding its services in these neighborhoods. For example, 7,500 children (in preschool and elementary school) benefit each year from the municipal oral health prevention program. One of the cornerstones of this program is the opening of pediatric dentistry clinics in three health centers.
