A scientific study published in the journal Nutrients revealed that oral and dental health may be linked to cognitive decline and an increased risk of dementia.
Researchers analyzed the results of several previous studies that examined the relationship between dental health, dietary habits, and changes in the brain. The analysis showed that tooth loss affects the brain through several pathways. Because of the difficulty in chewing food, people tend to give up vegetables, fruits, and foods rich in fiber and vitamins, preferring softer, less healthy foods. Also, the nerve signals that the teeth and the chewing process send to the brain are constantly decreasing.
According to studies, people with significant tooth loss often have changes in the size of the hippocampus and other brain regions responsible for memory, as well as changes in white matter. The findings suggest that these disturbances may appear even before noticeable cognitive symptoms develop.
The researchers pointed out that the habit of eating alone is an additional factor that increases the risks, as it is associated with a decrease in the quality of nutrition and a decline in the efficiency of some areas of the brain.
Scientists confirm that maintaining oral health, following a balanced diet, and engaging in an active social life may be among the most important means of preventing age-related cognitive decline.
A study conducted by researchers at the University of Cincinnati in the United States showed that gum disease may worsen the condition of patients with chronic kidney disease. Another study showed that periodontitis is associated with an increased risk of cardiovascular disease, diabetes, lung disease, rheumatoid arthritis, chronic kidney disease, and even Alzheimer's disease. Some research has also indicated a link between gum inflammation and strokes, heart attacks, and premature birth.
