Everyone is aware of the importance of brushing teeth to maintain their shape and oral health, but a recent study has indicated another crucial reason for brushing teeth – to avoid brain disease. The study found that the loss of a tooth in individuals with gum disease had an adverse effect on the hippocampus, the region of the brain associated with memory.
Gum disease is one of the most common causes of tooth loss, emphasizing the significance of maintaining dental health. Satoshi Yamaguchi from Tohoku University in Sendai, Japan explained, “The results indicate that retention of teeth with severe periodontal disease is associated with brain atrophy.” These findings highlight the need to prioritize dental health, not just preserving the teeth themselves.
The correlation between tooth loss and gum disease with brain atrophy is particularly important when assessing the potential link to dementia. Yamaguchi emphasized, “Tooth loss and periodontal disease, which is inflammation of the tissues around the teeth, can cause retraction of the gums and loosening of the teeth. Assessing the potential link to dementia is very important.”
The Japanese scientists discovered that the number of teeth and the level of gum disease were directly linked to changes in the left hippocampus of the brain, which is associated with Alzheimer’s disease. Alzheimer’s is the most common form of dementia and affects cognitive function, memory, behavior, and daily activities. It can lead to frustration, confusion, anxiety, and loss of self-esteem.
Yamaguchi stressed the need for regular dentist visits to control the progression of gum disease. In cases of severe gum disease, extraction of the affected teeth and replacement with appropriate prostheses may be necessary.
The study also found that individuals with mild gum disease at a younger age experienced a faster rate of contraction of the left hippocampus, equivalent to nearly a year of brain aging. Moreover, those with severe gum disease experienced faster brain shrinkage in the same region, equivalent to 1.3 years of brain aging per additional tooth.
These findings serve as a reminder of the importance of oral hygiene and regular dental check-ups, not only for maintaining healthy teeth but also for preserving brain health. Brushing teeth and preventing gum disease may have far-reaching benefits beyond just oral health.]
