Oral hygiene is generally taken casually among people. In a price-sensitive country, people use a single toothbrush for nearly a year or even more. Today's experts explain that if a toothbrush is not changed within a limited period it can increase risk of not just mere cavities or gum disease but more serious conditions like diabetes and heart disease. Our mouth is the home of around 700 bacterial species and if people take them casually they can trigger disease, inflammation and even travel beyond the gums. This article explores why you should replace your toothbrush every 3 months and why this simple habit impacts the whole body's health.
Long use of toothbrushes leads to poor oral hygiene which creates a haven for mouth bacteria to build up disease like plaque. When molecules of inflammatory areas and bacteria combine to enter the bloodstream they can reach to other organs of the body like the heart, liver or pancreas.
It can develop a relationship which impacts one another for say, high blood sugar weakens immune reaction so the infection of gums increases and toxins that are the product of the gum infection now interfere with insulin regulation.
How is gum inflammation related to heart? Chronic gum disease can lead to arterial stiffening or Atherosclerosis where arteries lose their ability to expand and contract, becoming less flexible and more rigid and this situation increases cardiovascular disease risk. Experts say that a person with untreated gum disease is almost twice as likely to suffer from cardiovascular disease then those with healthy gums.
The reason dentists suggest changing a toothbrush every three months is because overused brushes accumulate germs and frayed bristles that can't be cleaned easily. If you want a healthy mouth then start brushing twice a day, avoid tobacco and avoid sugary foods.
Changing toothbrush mindfully in three months is a small habit which is generally overlooked and it may have potential to influence one's overall health which beyond just teeth. The importance of mouth health is not about just mere cosmetic or bad breath, a healthy oral breaks the chain from gum infection to other disease such as diabetes, inflammation or heart disease.
