Doctor explains how your dental health could be causing dementia and strokes

Oral health is far more than just looking nice or having fresh breath — it’s associated with serious systemic conditions like dementia and strokes. Bad dental hygiene can let bacteria enter the bloodstream as well, which may affect both brain and heart health. Senior Dentist reveals the hidden links – and how to lower your risk.

Good oral health is often overlooked when it comes to preventing chronic diseases and conditions from diabetes to heart disease, but research is making those connections more clear. Bad dental hygiene isn’t only about cavities or bad breath, but it can also create a route for dangerous bacteria to enter the bloodstream. These bacteria can then go on to cause blood vessels and other essential tissues to become inflamed.

Research has shown a connection between chronic gum disease (periodontitis) and a range of neurological and cardio-vascular related conditions, including dementia and strokes. Inflammation in arteries – led by oral bacteria – can speed up plaque build-up, increasing a person’s risk of stroke. Likewise, toxins from an infected gum might affect the brain, perhaps promoting cognitive decline and dementia in time.

“Frequently ignored, dental visits can significantly reduce the risk of undesirable health issues. Patients don’t brush off an appointment with their cardiologist or neurologist — they pay them a visit,” says Dr. Nipun Gureja for DentaCare.
