OKLAHOMA: A new study published in The Journals of Gerontology Series A has revealed that poor dental health is directly associated with inflammation, brain tissue loss, and damage to the heart. The findings highlight the critical role oral health plays in overall well-being and challenge the conventional separation of dental care from broader health care systems.
The study, led by Dr. Benjamin Trumble of Arizona State University, analyzed the health of over 700 individuals from the Tsimané, an Indigenous community in Bolivia. Unlike industrialized societies, the Tsimané live a traditional lifestyle free from modern environmental and dietary factors that often complicate health studies.
Despite generally poor oral hygiene, individuals with significant tooth damage were found to have higher levels of inflammation, reduced brain size, and aortic valve calcification. These findings underline the profound impact of dental health on heart and brain function.
"Somewhere along the line, we lost this understanding when it comes to overall health and dental health," Dr. Trumble said, emphasizing the need to view the body as an interconnected system.
The study also sheds light on the disparity in how dental health is treated in industrialized societies. In many countries, including the U.S., dental care is often categorized as a non-essential service, excluded from standard health insurance plans.
"Health insurance and dental insurance are separated, but they both significantly impact our health and aging," Dr. Trumble explained.
This divide persists despite mounting evidence that poor oral health increases the risk of cardiovascular disease, strokes, Alzheimer’s disease, and other chronic conditions.
The Tsimané study offers a rare glimpse into how traditional lifestyles affect health. Free from the sedentary habits and processed diets of modern life, the Tsimané experience lower rates of industrialized diseases, providing researchers with a unique opportunity to isolate the effects of dental health.
Dr. Trumble described the experience of working with the Tsimané as transformative. "Modern urban life is evolutionarily novel — we are essentially living outside of the manufacturer's recommended warranty for our bodies," he said.
The findings call for a more integrated approach to health care, treating oral health as a cornerstone of overall well-being. Policymakers and health professionals are urged to reconsider the marginalization of dental care, ensuring it receives the attention and coverage it deserves.
This study not only deepens our understanding of the connection between dental and overall health but also serves as a reminder that maintaining oral hygiene is essential for protecting the heart and brain.
