Two new studies published in Neurology Open Access have found a strong link between oral health and brain health. The research, led by Dr. Souvik Sen at the University of South Carolina, shows that adults with gum disease are more likely to have signs of brain white matter damage and that having both gum disease and cavities is associated with an 86% higher risk of stroke compared to those with healthy mouths.

The studies also found that maintaining good oral hygiene, including regular brushing, flossing, and dental visits, can reduce the risk of stroke by up to 81%. With billions of people worldwide affected by gum disease or cavities, researchers emphasize that prevention and treatment of oral health issues could play a significant role in reducing stroke risk.

New research links gum disease and cavities to stroke risk

We know it's important to take care of our teeth and gums and see the dentist for regular check-ups and cleanings. Now, two new studies published in Neurology Open Access add to growing evidence that keeping your mouth healthy may help keep the brain healthy. The first study found adults with gum disease may be more likely to have signs of damage to the brain to white matter than people without gum disease. Gum disease is associated with a higher chance of inflammation and inflammation has been tied to atherosclerosis as well as hardening of the small blood vessels as we saw in this study. Dr. Souvik Sen with the University of South Carolina led both studies. The second found having both gum disease and cavities is linked to an 86% increased risk of stroke compared to people with healthy mouths. What the study suggested was that if you have cavities on top of gum disease, it is double trouble, means your risk of stroke or adverse heart event doubles. Some good news. Somebody took care of their mouth, including brushing, flossing, as well as visiting the dentist regularly for their preventative cleaning. Their risk of having a stroke dropped by as much as 81%, which is a very big finding. With 3.5 billion people worldwide suffering with gum disease or cavities, researchers say prevention and treatment could be an important part of stroke prevention. Jared Hill, CBS News.
