The Hidden Link Between Your Toothbrush and Atherosclerosis

A dental expert is warning of a hidden link between the state of your toothbrush and atherosclerosis, the dangerous hardening of your arteries. Using a brush for more than three months could be contributing to this serious heart condition.
Atherosclerosis is the “thickening or hardening of the arteries caused by a buildup of plaque.” According to a chief clinical officer, “chronic gum inflammation… can cause arteries to stiffen and narrow.” This inflammation starts in your mouth.
The process begins when the 700 species of oral bacteria form plaque. An old, frayed toothbrush is ineffective at removing this plaque. This leads to gum inflammation, which creates an entry point for bacteria to get into your bloodstream.
Once in the blood, these bacteria and inflammatory molecules travel to the heart, where they can contribute to arterial plaque. This is why “people with untreated gum disease are almost twice as likely to suffer from cardiovascular disease.”
To protect your arteries, you must stop the inflammation. Replace your toothbrush every three months. This ensures the bristles are effective, the plaque is removed, and your “first line of defense” is working.
