Study Links Oral Health to Increased Risk of Dementia

A scientific study published in the journal Nutrients has identified a potential link between oral and dental health and cognitive deterioration, as well as an elevated risk of dementia.

The researchers analyzed data from multiple previous studies examining the relationships among dental health, dietary habits, and brain changes. Their analysis indicated that tooth loss affects the brain through several pathways. Difficulty in chewing leads individuals to reduce consumption of vegetables, fruits, and foods rich in fiber and vitamins, favoring softer foods with lower nutritional value. Additionally, the continuous neural signals sent from teeth and the chewing process to the brain decrease.

According to the studies, individuals experiencing significant tooth loss often show changes in the volume of the hippocampus and other brain areas responsible for memory, alongside alterations in white matter. These brain disturbances may manifest before noticeable cognitive symptoms develop.

The researchers also noted that the habit of eating alone constitutes an additional risk factor, as it is associated with poorer nutritional quality and reduced efficiency in certain brain regions.

Oral Health’s Direct Impact on Cardiovascular Well-being

Scientists emphasize that maintaining oral health, adhering to a balanced diet, and engaging in an active social life may be among the most important strategies to prevent age-related cognitive decline.

A study conducted by researchers at the University of Cincinnati demonstrated that gum diseases can exacerbate conditions in patients with chronic kidney disease. Another study linked periodontitis to an increased risk of cardiovascular diseases, diabetes, lung diseases, rheumatoid arthritis, chronic kidney disease, and even Alzheimer’s disease. Additional research has suggested associations between gum inflammation and the occurrence of strokes, heart attacks, and premature births.
