You may have heard talk about the germs that can live on your toothbrush. But should you be concerned?
There are more bacteria in the mouth than anywhere else in your body, and some of them get on your toothbrush when you brush your teeth.
What’s more, most people store their toothbrushes in the bathroom, which tends to contain numerous airborne bacteria because of the warm, moist environment. If you cover up your toothbrush, the germs can thrive and multiply. The next time you use it, you may be introducing a host of bacteria and viruses into your body.
You can take some common-sense steps to remove most microorganisms from your toothbrush and limit the spread of disease. Follow these tips from the Centers for Disease Control and Prevention (CDC):
Some people use an antibacterial mouth rinse or toothbrush sanitizer to kill the germs. While these products don't do any harm and studies show they can remove microorganisms, they won’t remove all of them.
What you shouldn’t do is try to sterilize it using other methods. For instance, don’t put your toothbrush in the microwave or dishwasher. It could damage the toothbrush because it can’t withstand the extreme heat.
