There is now a compelling cardiovascular case for replacing your toothbrush every three months. It’s not just about cavities; it’s about preventing atherosclerosis, the dangerous hardening of your arteries.
Dental experts explain that the link is chronic inflammation. This inflammation starts in the gums when bacterial plaque isn’t properly removed. A common culprit is an old, frayed toothbrush.
When gums are inflamed, they become a source of systemic infection. The 700 species of bacteria in the mouth can get into the bloodstream, triggering a body-wide inflammatory response.
This systemic inflammation is a key driver of heart disease. It can damage the lining of your arteries and promote the buildup of the very plaque that causes them to stiffen and narrow.
Given that untreated gum disease can nearly double the risk of heart problems, the advice is clear. This simple, inexpensive habit is a powerful and necessary step in protecting your heart.
