Did you know poor oral health could be linked to Alzheimer’s disease? Studies increasingly show a strong connection between oral conditions – like gum disease (periodontitis) – and neurodegenerative diseases such as Alzheimer’s.
How does this happen?
The mouth is a gateway to the body, and infections or chronic inflammation can spread through the bloodstream to the brain. Porphyromonas gingivalis, a bacteria commonly found in gum disease, has been detected in the brains of Alzheimer’s patients. It can trigger an immune response, leading to brain inflammation and tissue damage, accelerating the disease’s progression.
What the research says
Chronic inflammation, often caused by untreated gum disease, is suspected to contribute to Alzheimer’s. A study published in the Journal of Alzheimer’s Disease (2016) found that long-term oral infections may drive beta-amyloid buildup – a key marker of Alzheimer’s.
“Poor oral health is associated with an increased risk of AD, demonstrating a 2.363-fold higher risk compared to those with normal oral health. Diseases like tooth loss, dental caries, periodontal disease, and gingivitis are linked to a higher risk of AD. Maintaining healthy oral hygiene may significantly reduce the risk of AD.”
What can you do?
Oral health is more than just a great smile – it’s essential for overall health. Regular brushing, flossing, and dental checkups can help protect your mouth and potentially safeguard your brain from long-term damage. It’s also crucial to update old dental treatments and address any hidden problems. If you want to quickly check, consider using Missing Link to screen your recent panoramic X-ray, and get a 3D CBCT with an expert dentist and treatment if needed.
At the White Clinic, my team and I focus on integrative health, recognising the profound link between oral and systemic diseases. Our ongoing research aims to integrate oral care into broader health management, helping protect both your mouth and mind.
