The study examines the association between social determinants of health, tooth loss, and cognitive decline. Using regression models, the 2020 Behavioral Risk Factor Surveillance data examined the study objective; it included 32,663 older adults who reported on cognitive status. Results suggested that older adults missing more than five teeth or unable to work are 1.61 times and 6.84 times more likely to report cognitive decline, respectively. Older adults with higher education and higher household incomes are less likely to report cognitive decline. Results suggested that older adults with no diabetes or who never smoked are 31% and 39% less likely to report a cognitive decline. The results suggested a significant association between tooth loss and cognitive decline among social determinants of health. A comprehensive approach to affect cognitive decline should include oral and social health strategies.
