What if a simple, 90-day rule could significantly lower your risk of heart disease? According to dental experts, it can. The rule: replace your toothbrush every three months. The reason: to prevent the inflammation that leads to hardened arteries.
This serious condition, known as atherosclerosis, has a surprising link to the bacteria in your mouth. When these bacteria form plaque and are not removed, they cause chronic inflammation in the gums.
An old toothbrush with frayed, matted bristles is a primary accomplice in this process. It’s simply not effective at removing the plaque that triggers the inflammation.
This oral inflammation is a gateway. It allows the mouth’s vast population of bacteria to enter the bloodstream, along with inflammatory molecules. This turns a local dental issue into a systemic problem.
These circulating particles can then travel to the heart’s arteries, where they contribute to the plaque buildup that causes stiffening and narrowing. Adhering to the “three-month rule” is a powerful, low-cost strategy for preventive heart care.
