Doctors are identifying a surprising risk factor for atherosclerosis, the dangerous narrowing of arteries. It’s not just diet or smoking; it’s your toothbrush. An old, worn-out brush can kickstart a chain reaction that ends with damaged arteries.
The process is rooted in inflammation. A chief dental expert explains that chronic gum inflammation, often caused by poor plaque removal, can lead to stiffening and narrowing of your arteries.
When a toothbrush’s bristles are frayed, they can’t remove the bacterial film called plaque. This plaque irritates the gums, causing a persistent, low-grade infection. This infection signals a problem to your entire immune system.
The mouth is a gateway. When gums are inflamed, they allow oral bacteria and inflammatory signals to enter the bloodstream. These elements can then circulate and contribute to the formation of plaque in the arteries, far from the original source.
This is why people with severe gum disease face a much higher risk of heart problems. To protect your arteries, begin by protecting your gums. The primary rule is simple: change your toothbrush every three months to ensure it’s doing its job.
