A comment on tooth health and cognition

Updated: Aug 3, 2023

I commented on a news article from Medical News Today about a recent paper in the Journal of the American Geriatrics Society ("Periodontal health, cognitive decline, and dementia: A systematic review and meta-analysis of longitudinal studies"):

"“Poor oral health and non-optimal mastication have been found to be potentially modifiable risk factors for cognitive impairment, but previous evidence is limited. This meta-analysis provides a much-needed comprehensive synthesis of a large number of longitudinal studies regarding periodontal health, cognitive decline, and dementia.”

“This paper is novel in several regards, such as taking reverse causality into account, covering the spectrum of periodontal deterioration, including tooth loss, and examining both cognitive decline and dementia as outcomes. Their findings can indicate the importance of policies and interventions that address tooth loss, even partial loss, in old age,”
