Brushing Your Teeth May Help Protect More Than Your Smile. It May Also Help Protect Your Heart.
Most people brush their teeth to prevent cavities and gum disease.
But growing research suggests that this simple daily habit may also be associated with better cardiovascular health.
A study published in the International Journal of Cardiology—found that adults who brushed their teeth at least twice a day for two minutes had a significantly lower risk of major cardiovascular events. In contrast, people who brushed less than twice daily and for less than two minutes had about a threefold higher risk of cardiovascular death, heart attack, heart failure, or stroke, even after adjusting for multiple cardiovascular risk factors.
Scientists believe one possible explanation is inflammation. Poor oral hygiene allows dental plaque to accumulate, increasing the risk of gum disease. Chronic gum inflammation may enable oral bacteria and inflammatory molecules to enter the bloodstream, where they could contribute to blood vessel dysfunction and cardiovascular disease. However, it is important to remember that this study shows an association, not proof that brushing itself prevents heart disease. Other healthy lifestyle factors may also play a role.
The good news is that brushing twice a day with fluoride toothpaste for at least two minutes is a simple, inexpensive habit already recommended for maintaining healthy teeth and gums. It may also support overall health as part of a heart-healthy lifestyle.
