Abstract: Objectives: To examine the association between the number of teeth remaining and cognitive decline among Chinese older adults over a 13-year period. Design: A large national longitudinal survey of Chinese older adults Setting: The Chinese Longitudinal Healthy Longevity Survey (CLHLS) (1998–2011). Participants: A total of 8,153 eligible participants aged 60+ interviewed in up to six waves. Measurements: Cognitive function and teeth number were measured at each interview. Cognitive function was measured by the Mini-Mental Status Examination (MMSE). Number of natural teeth was self-reported. Individuals with severe cognitive impairment were excluded. Covariates included demographic characteristics, adult socioeconomic status characteristics, childhood socioeconomic status, health conditions, and health behaviors. Linear mixed models were applied in the analysis. Results: The mean teeth number at baseline was 17.5(SD = 0.1), and the mean of baseline cognitive function was 27.3(SD = 0.0). Cognitive function declined over time (β = -0.19, P
