Atherosclerosis and Gum Disease: A Clinical Connection

A dental expert is highlighting the clinical connection between chronic gum inflammation and atherosclerosis, the underlying cause of most heart attacks and strokes. The culprit, he warns, is often an ineffective oral hygiene routine.
Atherosclerosis is the “thickening or hardening of the arteries caused by a buildup of plaque in the inner lining.” A chief clinical officer explains that the chronic inflammation from your gums can directly cause this arterial stiffening and narrowing.
The mechanism starts with oral bacteria. When the 700 species in the mouth form plaque, they trigger an inflammatory response. This inflammation allows bacteria and cytokines to enter the bloodstream, where they can travel to the heart and blood vessels.
This is why “people with untreated gum disease are almost twice as likely to suffer from cardiovascular disease.” The body’s constant immune battle against the oral infection places a significant, long-term strain on the heart’s defenses.
To mitigate this risk, the expert advises replacing your toothbrush every three months. An old brush with frayed bristles cannot remove the plaque that initiates the inflammatory cascade. This is a critical component of cardiovascular risk reduction.
