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.
