Description: Abstract Background Regular dental visits are essential for oral health, yet disparities between regions exist due to socioeconomic and geographic factors. While national surveys provide valuable data on dental care utilization, they generally lack sufficient sample sizes at the local level to generate reliable county-level estimates. Small area estimation techniques, such as multilevel regression and post-stratification (MRP), can help address this gap by producing robust estimates for smaller geographic areas. However, the MRP approach relies on detailed population data in the form of joint distributions and cannot be applied when only marginal distributions are available. Methods This paper introduces a hybrid approach combining multilevel modeling with the raking procedure. We used individual-level data from the 2018 Behavioral Risk Factor Surveillance System (BRFSS) and census data from American Community Survey to estimate county-level dental care utilization among adults in California. Results The county-level dental care utilization in California ranged from 52.5 to 73.1%, with a median of 63.1%. Our model-based estimates matched direct BRFSS estimates at metropolitan and micropolitan statistical area levels. Furthermore, we found significantly positive correlations between our model-based estimates and direct estimates from the California Health Interview Survey for 41 counties (Pearson coefficient: 0.801, P
