That worn-out toothbrush you keep using could be quietly contributing to one of the biggest killers: heart disease. Dental professionals warn that poor oral hygiene allows bacteria to trigger inflammation that directly impacts your cardiovascular system.
According to a leading dentist, chronic gum inflammation is a key culprit. It can cause arteries to stiffen and narrow, a condition known as atherosclerosis. This thickening of the artery walls is caused by plaque buildup and puts a severe strain on your heart over time.
The process starts in the mouth. Home to 700 bacterial species, the mouth requires regular cleaning. Skipping brushing, or using a frayed brush, allows bacteria to form plaque and trigger inflammation. These bacteria and inflammatory agents then enter the bloodstream, traveling directly to the heart.
This systemic inflammation is why people with untreated gum disease are almost twice as likely to suffer from cardiovascular disease as those with healthy gums. The body’s constant immune response to the oral infection simply wears down the heart’s defenses.
To protect your heart, start in your bathroom. Replace your toothbrush every three months. An old brush loses its effectiveness, and its worn bristles can’t disrupt the plaque that starts this dangerous chain reaction. Brushing twice daily with a fresh brush is a critical step for heart health.
