According to one study out of Ewha Women’s University in Seoul, brushing your teeth more than once in the morning and once at night could reduce your risk of heart failure by more than 10 per cent.
Using data from the Korean National Health Insurance System, researchers analysed the oral hygiene of more than 160,000 people aged between 40 and 79 over a 10-and-a-half-year period. The data also included details about their height, weight, lifestyle choices and any illnesses they had previously suffered.
While none of the participants had a history of atrial fibrillation (a condition that causes and heart failure) three per cent of the participants developed it over the course of the study. In addition, approximately five per cent experienced heart failure.
The researchers established a link between those participants who brushed their teeth three or more times a day and a 10 per cent lower risk of developing atrial fibrillation, as well as a 12 per cent reduced risk of suffering from heart failure. Admittedly though, more research is needed on the topic as the “causality of these associations is unclear:”
“It is certainly too early to recommend toothbrushing for the prevention of AF [atrial fibrillation] and CHF [congestive heart failure],” the study’s authors note.
“While the role of inflammation in the occurrence of cardiovascular disease is becoming more and more evident, intervention studies are needed to define strategies of public health importance.”
