Cleaning your teeth often, every day, is linked to a lower risk for heart problems. A new study found that brushing your teeth several times a day resulted in fewer cases of heart failure and atrial fibrillation— the term for an uneven heartbeat.

Heart failure happens when the heart cannot do its job of pumping blood through the body.




What the research found is that brushing your teeth three times a day, or more, was linked to a ten percent lower risk of atrial fibrillation. It was also linked to a twelve percent lower risk of heart failure.

The study was published last Monday in the European Journal of Preventive Cardiology.



The researchers examined information on more than 161,000 people in Korea with no history of heart problems.

They followed up ten and a half years later, and found that three percent had developed uneven heart rhythms and almost five percent had developed heart failure.




All the participants in the study were part of the Korean National Health Insurance System, and aged 40 to 79. They had usual medical exams between 2003 and 2004. Information was collected on their height, weight, laboratory tests, sicknesses, and lifestyle. They also noted their mouth health in connection with cleaning.


Heart and teeth health connection

You may wonder, how are teeth health and heart health connected?

Earlier research suggests that not taking care to clean and brush teeth leads to bacteria in the blood. This can cause inflammation, and increases the risk for unusual heartbeat and heart failure.



A study last year by the American Heart Association showed that brushing your teeth twice a day for at least two minutes may lower the risk of cardiovascular, or heart, diseases.

That study looked at a smaller group of fewer than 700 people. The AHA said that the researchers found that people who brushed less than twice a day for less than two minutes were three times more at risk, compared to those who brush at least twice a day for two minutes.


该研究针对的是人数少于700人的较小群体。 AHA说,研究人员发现,每天刷牙少于两分钟,少于两分钟的人的风险是每天刷牙两次,少于两分钟的人的三倍。


Gums are the soft tissue structure that hold the teeth. They need to be cleaned as well. Experts say if gums are not cared for this way they can become inflamed. They say there is a connection between such inflammation, and future heart disease.

The lead investigator of the new study is Tae-Jin Song, a doctor and professor at Mokdong Hospital at Ewha Womans University in Seoul, South Korea. He noted "we studied a large group over a long period, which adds strength to our findings."


这项新研究的主要研究者是韩国首尔梨花女子大学木洞医院的医生兼教授Tae-Jin Song。他指出:“我们长期研究了一大群人,这为我们的发现增加了力量。”

But he said that the research was limited to one country and as an observational study does not prove causation.

The American Dental Association agrees. The organization said "this study is interesting, and while it may suggest an association between tooth brushing and heart health, it does not show a direct connection."

To have good oral health, the ADA advises people to:




  • Brush their teeth twice a day for two minutes each time with a fluoride toothpaste

  • Clean between their teeth once per day

  • Maintain a healthy diet

  • See a dentist regularly

  • 每天两次用氟化物牙膏刷牙,每次两分钟

  • 每天清洁一次牙齿

  • 保持健康饮食

  • 定期去看牙医

Mouth care companies have taken note. Some manufacture electric toothbrushes programmed to run for two minutes. That way, people do not have to watch the time while brushing their teeth.

口腔护理公司已经注意到。 一些制造的电动牙刷编程运行两分钟。 这样,人们在刷牙时就不必看时间。
