AbstractFunctional ageing, including dental health, was studied in the gerontological population study in Gothenburg. This study was based on three 70‐yr‐old cohorts, born in 1901–2, 1906–7, and 1911–12 (n= 1380). The Eichner index was used as a measurement of deterioration in dental state and dental functional impairment. This impairment was significantly associated with a lower capacity in cognition, visual ability, hearing ability, lung volume, heart volume, muscle strength, and bone mineral content as well as a lower self‐assessment of health. A multiple regression model showed that an index of seven functional capacities was the most predictive factor for dental status independent of confounding factors such as socio‐economic factors, tobacco smoking, and the most incapacitating diseases. These associations were more marked in men and the survival rate between 70 and 79 years of age was higher among men with a well preserved dental state of the age of 70. The co‐variation between impairment in dental function and other functional variables and survival indicate a common fu
