Recently, researchers at the Rory Meyers School of Nursing at New York University found that tooth loss is a risk factor for cognitive impairment and dementia.
According to the US Centers for Disease Control and Prevention, about one in six adults aged 65 and over have lost all their teeth
The senior author of the study, Bei Wu, professor of the Department of Global Health at the New York University Rory Meyers School of Nursing, and co-director of the New York University Aging Incubator, and colleagues conducted a meta-analysis using longitudinal studies of tooth loss and cognitive impairment
Researchers found that after controlling for other factors, adults with more tooth loss had 1.
However, adults with missing teeth who do not use dentures are also more likely to have cognitive impairment than those of the same population who use dentures.
The researchers also analyzed a subset of eight studies to determine whether there is a "dose-response" association between tooth loss and cognitive impairment
Their findings confirm this relationship: For every missing tooth, the risk of cognitive impairment increases by 1.
"The'dose-response' relationship between the number of missing teeth and the risk of cognitive decline greatly strengthens the link between missing teeth and cognitive impairment, and provides some evidence that tooth missing may indicate cognitive decline
Bei Wu said the research findings emphasize the importance of maintaining good oral health and its role in helping to maintain cognitive function
