Poor oral health has important implications for the healthy development of children. Children in Medicaid, especially Latinos and African Americans, experience high rates of tooth decay, yet they visit dentists less often than privately insured children. Even Latino and African American children with private insurance are less likely than white children to visit dentists and have longer intervals between dental visits. Furthermore, Latino and African American children in Medicaid are more likely than white children in Medicaid to have longer intervals between visits. These findings raise concerns about Medicaid’s ability to address disparities in dental care access and, more broadly, in health care.
