A study published in the International Journal of Cardiology found that adults who brushed their teeth at least twice daily for two minutes had a significantly lower risk of major cardiovascular events than those who brushed less frequently.
Researchers believe chronic gum inflammation may allow oral bacteria and inflammatory molecules to enter the bloodstream, where they could contribute to cardiovascular disease. However, the study shows an association and does not prove that brushing itself prevents heart disease.
Brushing twice daily with fluoride toothpaste remains one of the simplest and most effective habits for maintaining healthy teeth, healthy gums, and potentially supporting overall health.
