Multiple published studies now link reduced chewing ability in older adults to lower nutritional status and a measurably higher risk of cognitive decline — not just difficulty eating. Losing teeth or wearing an ill-fitting denture often quietly pushes people toward softer, lower-fiber foods for years before anyone notices the nutritional impact. Protecting your ability to chew starts decades early: address a damaged tooth with restorative care instead of delaying it, replace missing teeth rather than leaving gaps, and treat jaw or bite discomfort as worth fixing now, not living with.
