Tooth decay is child’s overall a serious public health problem that can affect a health and well-being. It can lead to pain and disfigurement, low self-esteem, nutritional problems, and lost school days. Children with oral health problems are three times more likely to miss school due to dental pain and absences caused by pain are associated with poorer school performance.1 Even though tooth decay can be prevented, many children in Nevada still get cavities. To assess the current oral health status of Nevada’s elementary school children, the Nevada Department of Health and Human Services coordinated a statewide oral health survey of third grade children attending Nevada’s public schools. A total of 1,187 third grade children received a dental screening at 45 schools during the 2022-2023 and 2023-2024 school years. This data brief presents information on the prevalence of tooth decay in the primary and permanent teeth of Nevada’s third grade children compared to the general U.S. population screened between 2011-2016 as part of the National Health and Nutrition Examination Survey (NHANES). It also describes the prevalence of dental sealants, a plastic-like coating applied to the chewing surfaces of teeth to prevent tooth decay.
