A study done by the department of neurology at Mokdong Hospital at Ewha Womans University College of Medicine in Seoul, South Korea analyzed data from over 160,000 people who had no history of heart failure or atrial fibrillation. Information collected during the study included weight, height, lifestyle questionnaires, lab tests, oral health disease, dental visits in the past year, and oral hygiene behaviors.
All study participants were examined for periodontal disease. Of all participants present, 3% developed atrial fibrillation and 4.9% developed heart failure after a follow up 10.5 years later.
The study found that people who frequently brushed their teeth (3 or more times per day) had a lower risk of heart failure and atrial fibrillation. Getting teeth professionally cleaned also lessened risked of these problems.
More research is needed to see if there is a causal relationship. However, recommending active oral hygiene is always a great idea!
