Adopting a healthier lifestyle by incorporating regular exercise, quitting smoking, and maintaining a balanced diet is widely recognized for its role in enhancing cardiovascular health and reducing the risk of strokes. However, a recent study has introduced a surprising addition to this list of beneficial habits: brushing your teeth.

The research highlights a significant link between oral health and stroke risk. Individuals suffering from both gum disease and cavities were found to have an 86% higher likelihood of experiencing a stroke compared to those maintaining good oral hygiene. Moreover, poor oral health was associated with a 36% increased risk of heart attacks and other cardiovascular issues.

Dr. Souvik Sen from the University of South Carolina in the USA emphasized the broader implications of dental care, stating, “This study underscores that dental hygiene is not solely about aesthetics; it could also play a crucial role in safeguarding your brain.”

Dr. Sen further advised that, “People exhibiting signs of gum disease or cavities should seek treatment not only to preserve their dental health but also to potentially lower their stroke risk.”

The study specifically pointed to an increased risk of ischaemic stroke, the most prevalent type, which occurs when a blood clot obstructs the circulation of blood and oxygen to the brain. This blockage can lead to a deprivation of essential oxygen and nutrients, potentially resulting in permanent damage to the brain.

This deprives the brain of oxygen and nutrients, which can lead to permanent damage.

The study involved almost 6,000 adults with an average age of 63, who had no history of stroke at the start of the study. 

Some 10% of those with gum disease and cavities suffered a stroke during a follow-up period of 20 years, compared with 4% of those with healthy mouths.

The research also found that people who regularly went to the dentist were 81% less likely to have gum disease and cavities.

The findings were published in the journal Neurology Open Access.
