Married older individuals, especially men, had more teeth than those who didn’t have spouses, which was mediated by better oral health habits like toothbrushing. In individuals with spouses, the mean number of teeth was higher (men: 18.49 [standard deviation (SD) = 10.00]; women: 20.08 [SD = 8.88]). In those who were not married, the mean number of teeth was lower (men: 16.34 [SD = 10.34]; women: 17.22 [SD = 10.35]), the authors wrote. Initiatives could be developed that focus on ensuring that unmarried individuals receive the support needed for optimal oral health, the authors wrote. “In conclusion, being married in old age offers a range of benefits that contribute to the maintenance of oral health,” Aida and colleagues wrote.
