Medicaid Dental Benefits for Pregnant People and Dental Care Use Among Very Young Children.

Objectives: The aim of this study was to examine the association between Medicaid dental benefits for pregnant people and dental care use among very young children in Medicaid. We hypothesized that children living in states with more generous dental benefits for Medicaid-enrolled pregnant people would be more likely to have a recent dental visit.

Methods: This national cross-sectional study used pooled 2017-2019 data from the National Survey of Children's Health, as well as state Medicaid policy data. The study sample included children aged 0-2 enrolled in Medicaid. Multivariable logistic regression models estimated the association between Medicaid dental benefit generosity for pregnant people and the child having a dental visit in the past year.

Results: Children in states with emergency-only dental coverage for pregnant people were 2.5 times as likely to have had a dental visit than children in states with extensive coverage (OR 2.48, 95% CI 1.35-4.53). In supplemental analyses excluding children living in Texas, there was no longer an association between dental coverage for pregnant people and dental utilization among young children (OR 1.52, 95% CI 0.82-2.83).

Conclusions for practice: Young children in states that provided emergency-only dental benefits for pregnant people in Medicaid had significantly higher odds of dental utilization than young children in states with more generous dental benefits for pregnant people. This relationship disappeared after excluding the state Texas, which had the highest rate of child dental utilization in the country and provided emergency-only dental benefits for pregnant people in Medicaid.
