Think of your toothbrush as a security guard for your body. According to a chief clinical officer, its role is to act as a “gatekeeper,” preventing infections in your mouth from escalating into body-wide problems. But if that guard is old and worn out, it can’t do its job.
The danger begins with bacteria. Your mouth contains around 700 species. When you don’t brush properly, they form sticky plaque, trigger inflammation, and create an entry point into your bloodstream. From there, they can travel “silently” to your heart.
This is where the heart disease risk becomes real. Chronic gum inflammation can cause arteries to stiffen and narrow—a condition called atherosclerosis. This puts a major strain on your heart. People with untreated gum disease are nearly twice as likely to develop cardiovascular disease.
This systemic inflammation also complicates other conditions, like diabetes. A “two-way” relationship exists where high blood sugar weakens gums, and infected gums make blood sugar harder to control.
The key to keeping the “gatekeeper” effective is maintenance. Replace your toothbrush every three months. An old brush with frayed bristles can’t clean properly and may harbor germs. This simple habit is a frontline defense for your heart and overall health.
