The association between the number of teeth and frailty among older nursing home residents: a cross-sectional study of the CLHLS survey

Abstract

Older nursing home residents who maintain their natural teeth can help lower the risk of frailty, and regular toothbrushing also contributes to decreasing the risk of frailty. Our study emphasizes the importance of oral health, and cohort studies with large-scale samples to address this important issue are warranted in the future.
