According to a new research published in the European Journal of Preventive Cardiology - brushing teeth frequently is linked with lower risks of heart failure and atrial fibrillation (irregular heartbeat).
Previous research under this subject also examined the connection between the occurrence of heart failure and atrial fibrillation with oral hygiene. It suggested that the inflammation caused due to bacteria in the blood as a result of poor oral hygiene increases the risk of heart failure and atrial fibrillation.
The current study used the data from Korean National Health Insurance System. It enrolled 161,286 participants with no history of atrial fibrillation or heart failure. Participants aged between 40 – 79.
Between 2003 – 04, participants underwent routine medical examinations. Apart from oral hygiene behaviors, information was collected on weight, height, illness lifestyle, etc.
The study findings suggest that 7,971 (4.9%) developed heart failure and 4,911 (3.0%) participants developed atrial fibrillation during a median follow up of 10.5 years. Also, a 12% lower risk of heart failure and a 10% lower risk of atrial fibrillation was found to be associated with tooth brushing three or more times a day during follow up years.
The study did not take into consideration factors like alcohol consumption, socioeconomic status, regular exercise, etc.
Though the research did not study the mechanisms behind these observed associations. However, the possibility could be that the frequent brushing reduces the bacteria in living in the pocket between the teeth and gums (subgingival biofilm). This reduction prevents the translocation of these bacteria in the bloodstream.
Though other experts believe that this is a country-based observation and the subject demands further more research to recommend it.
