Children's oral health and oral health care use during the first 2 years of the COVID-19 pandemic.

Background: The COVID-19 pandemic has been associated with declines in children's oral health and oral health care use in 2020. The authors examined the pandemic effects on these outcomes into 2021.

Methods: This cross-sectional study used data from the National Survey of Children's Health from 2017 through 2021. The authors compared parent's or caregiver's perceptions of the child's oral health and reported dental problems and dental visits across years, adjusting for child and household covariates and state of residence. The authors evaluated potential heterogeneity across demographic and socioeconomic subgroups.

Results: In 2021, parents and caregivers were still more likely to perceive children's oral health as poor (odds ratio [OR], 1.90; 95% CI, 1.28 to 2.82) and less likely to report very good or excellent oral health (OR, 0.83; 95% CI, 0.76 to 0.92) than in 2019, similar to differences between 2020 and 2019. Dental visits were also less likely in 2021 than 2019 (OR, 0.74; 95% CI, 0.66 to 0.83). These differences between 2021 and 2019 were not explained by prepandemic trends and were observed across a range of demographic and socioeconomic subgroups.

Conclusions: Children's oral health as perceived by parents and caregivers and oral health care use were still worse in 2021 than before the pandemic both overall and across demographic and socioeconomic subgroups.

Practical Implications: The persistent adverse effects of the COVID-19 pandemic on children's oral health as perceived by parents and caregivers and shown through dental visits highlight the need to improve oral health care access and use and to evaluate the long-term effects of the pandemic on children's oral health.
