The Arterial Danger of a Worn-Out Toothbrush

The bristles on your toothbrush are directly related to the health of your arteries. According to a dental professional, using a brush with frayed bristles allows for inflammation that can lead to atherosclerosis, the dangerous stiffening and narrowing of your arteries.
This process starts in the mouth but ends at the heart. When the 700 species of oral bacteria are not properly cleaned, they form plaque. This plaque causes gum inflammation, which allows bacteria and inflammatory molecules to enter the bloodstream.
Once in the bloodstream, they can contribute to plaque buildup within the artery walls. This is why people with untreated gum disease have almost double the risk of cardiovascular disease. Their body is in a constant state of immune response, which strains the heart.
This inflammation also creates a “vicious cycle” with diabetes. High blood sugar weakens the gums, and the resulting infections make blood sugar harder to control.
The expert advice is to attack the problem at its source. Replace your toothbrush every three months. This ensures the bristles are effective at removing the plaque that causes this systemic inflammation, thereby protecting your arteries.
