Where things stand
Preventing and treating gum disease protects the tissues that support teeth and helps preserve oral health. That practical benefit should not depend on a longevity claim. Links between oral health and wider disease are a separate research question; evidence that dental treatment improves gums is not, by itself, evidence that it prevents dementia or extends life.

Evidence events affecting this intervention
Systematic review links dysbiotic oral microbiome and age-related inflammation in elderly periodontitis
This narrative systematic review synthesized mechanistic studies, human cohorts, and preclinical models to examine how oral dysbiosis interacts with age-related immune dysfunction in periodontitis among older adults. The authors found that aging alters immune responses to oral pathogens through mechanisms including impaired TLR9 sensing, amplified inflammasome-macrophage responses to P. gingivalis, and accumulation of senescent cells that promote inflammation. At the systemic level, periodontitis was associated with multi-organ frailty-like features, neuroinflammatory changes, and persistent gut dysbiosis.
