Purpose
Sleep deficiency is implicated as a risk factor for several systemic conditions. Loss of teeth has a profound effect on the individual’s physiologic and psychologic health and quality of life. This study aimed to assess the association between tooth loss and sleep duration and determine if anterior and/or posterior tooth loss is a significant predictor.
Methods
A total of 22,483 individuals ≥ 18 years who participated in the United States National Health and Nutrition Examination Survey (NHANES) 2005–2016 cycles were included. Multinomial logistic regression adjusted for age, gender, race/ethnicity, smoking, diabetes, body mass index, socioeconomic level, education, alcohol, and depression was performed to examine the association between sleep duration and tooth loss.
Results
Compared to individuals with > 20 remaining teeth, those who were completely edentulous, had 1–10 or 11–20 teeth remaining were more likely to be in the deficient sleep category (OR [95% CI] = 1.59 [1.35–1.87], 1.29 [1.07–1.54], and 1.26 [1.11–1.43], respectively). When the numbers of both missing anterior and posterior teeth were entered in the model, only posterior teeth were significant. There was a 4% increase in the odds of being in the deficient sleep category for each missing posterior tooth (OR [95% CI] = 1.04 [1.02–1.05]).
Conclusions
Tooth loss was significantly associated with deficient sleep and posterior tooth loss appeared to be the main contributor. Although further research is needed to clarify the nature of this association, our results suggest that improving oral health might have an impact on overall health and quality of life.
