Bacteria from infected gums travels to the brain
Could taking good care of gums and teeth also help to protect the brain? A recent study has added to growing evidence of a link between severe gum disease, or periodontitis, and a raised risk of dementia.
New research suggests that keeping your gums healthy may prevent dementia.
Using data from an extensive national health insurance screening program, investigators from Seoul National University in South Korea examined the relationship between chronic periodontitis and dementia.
In a paper that now features in the Journal of the American Geriatrics Society, the researchers describe how they found a modest link between severe gum disease and dementia, which is consistent with some previous studies.
