দাঁতের দীর্ঘদিনের ক্ষয় কয়েক বছর পরে আপনার ডিমেনশিয়া অর্থাৎ এক ধরনের ভয়াবহ স্নায়ুরোগ সৃষ্টি করে।
Scientists are now uncovering a concerning connection between untreated tooth decay and faster cognitive decline in the years that follow.
A large population-based study from University of Helsinki, published in PLOS Medicine, found that people with severe infections — including advanced tooth decay — had a significantly higher risk of developing dementia within the next 5–6 years.
One key mechanism is inflammation. Chronic dental infections can trigger systemic inflammatory responses that may affect the brain, potentially disrupting protective barriers and contributing to neurodegenerative processes seen in conditions like Alzheimer’s disease.
In early-onset dementia (before age 65), the association appeared even stronger, with infections such as tooth decay linked to nearly double the risk. While this does not prove direct causation, the evidence continues to grow.
The message is simple but critical: untreated tooth decay is not just a local problem. Early diagnosis, timely treatment, and prevention may play a role not only in saving teeth — but also in protecting long-term brain health.
