Nuevos estudios asocian la mala higiene dental con la disminución del hipocampo. La salud dental cada día se asocia más con el bienestar individual del individuo.
A recent study from Japan found a troubling connection between dental health and brain function, showing that tooth loss and gum disease are linked to shrinkage in the hippocampus—the part of the brain involved in memory and Alzheimer's disease. The study followed 172 adults aged 55 and older for four years, tracking their dental health and brain volume through MRI scans. Those with mild gum disease who lost teeth experienced faster shrinkage of the hippocampus, roughly equivalent to aging the brain by an extra year for each lost tooth.
Surprisingly, people with severe gum disease who kept more teeth also showed faster brain shrinkage, suggesting that holding onto diseased teeth might harm brain health. Researchers say this highlights the importance of not just keeping teeth but ensuring they’re healthy, emphasizing regular dental care to control gum disease. While this study doesn’t prove cause and effect and involved a small, localized group, it adds to growing evidence that oral health affects cognitive function. These findings serve as a powerful reminder that looking after your teeth could play a vital role in protecting your memory and brain health as you age.
