Objectives The goal of this study was to investigate inequality in dental service utilization in Chinese middle‐aged and senior adults and changes in inequality over time and to determine the sources of inequality. Methods The data included 17 648 individuals aged 45 years and older in 2013 and 15 450 individuals in 2015 who participated in the China Health and Retirement Longitudinal Study ( CHARLS ). The concentration index was used to quantify the degree of inequality. A decomposition method was employed to determine the sources of inequality, including need variables (demographic characteristics, self‐reported health status, and presence of chronic diseases), living standard (measured by household consumption expenditure per capita), other non‐need variables (education level, marital status, region of residence, urban–rural difference and type of health insurance plans). Results The better‐off not only had a higher likelihood of using dental care services than did the worse‐off but also used them more often than the worse‐off. The concentration index for probability of dental care utilization increased from 0.074 to 0.112 between 2013 and 2015, and the concentration index for total number of dental visits increased from 0.085 to 0.127. Living standard, education, health insurance plans and urban–rural disparities showed a pro‐rich contribution to the inequality. The living standard contributed about 70% to the pro‐rich inequality. Conclusions Dental care utilization in the Chinese middle‐aged and older adults was concentrated in the better‐off. Inequality in dental care utilization widened from 2013 to 2015. Achieving equity in dental care utilization remains a challenge for the healthcare system in China.
