Is There a Link Between Dental Hygiene and Dementia?

In recent years, research has shown a potential link between poor oral hygiene and the development of dementia.

Studies have shown that oral infections and inflammation can increase the levels of certain substances in the bloodstream, such as cytokines, which can lead to brain inflammation and subsequent cognitive decline. Poor oral hygiene can lead to conditions such as gum disease and tooth loss, both of which have been associated with an increased risk of developing dementia. A study published in the Journal of Alzheimer’s Disease found that individuals with gum disease were 70% more likely to develop dementia compared to those with healthy gums.

Moreover, oral bacteria have been found in the brain tissue of individuals with Alzheimer’s disease, suggesting a potential link between poor oral hygiene and the development of this condition. The oral bacteria can enter the bloodstream and reach the brain, where they can contribute to the formation of amyloid plaques, which are hallmarks of Alzheimer’s disease.

Additionally, poor oral hygiene can lead to a decrease in the quality of life and increase the risk of malnutrition in older adults. Malnutrition has been linked to cognitive decline and an increased risk of developing dementia.

The available evidence suggests that poor oral hygiene is associated with an increased risk of developing dementia. Maintaining good oral hygiene practices, such as brushing teeth twice a day, flossing regularly, and visiting the dentist regularly, can help to reduce the risk of oral infections and inflammation, and potentially reduce the risk of developing dementia.

More research is needed to fully understand the relationship between poor oral hygiene and the development of dementia, but the available evidence highlights the importance of maintaining good oral hygiene practices for overall health and well-being. It is definitely worth consider incorporating oral health assessment and intervention into care plans for older adults, especially those at risk for developing dementia.
