It’s something most of us do multiple times a day and think nothing of it – brushing our teeth. In our strive for oral health, though, there’s an unpleasant truth that you’d probably rather not know.
Toothbrushes are filthy.
Yes, a bacteria-ridden, germ-infested, icky mess.
According to researchers at the University of Alabama-Birmingham, toothbrushes are home to more than 100 million bacteria which can include, among many other things, E. coli and staphylococci (Staph) bacteria. Even the plaque we’re trying to get off our teeth is basically a germ stew.
If that’s not enough to lead to a sideways look at your toothbrush, consider this factoid: Most of us store our trusty toothbrush at the bathroom sink and because the sink is usually located pretty close to the toilet, most toothbrushes the researchers examined also contained fecal matter. When you flush, bacteria particles can be sent flying, unseen, for as many as six feet from the commode, according to experts.
Before you go off screaming into the morning, though, the university study pointed out another thing. Because our mouths are naturally already teaming with bacteria and germs, some that aid in the digestion process, it’s unlikely that your toothbrush can make you sick. Unless you share a toothbrush with someone else (DON’T!) or brush too hard and push bacteria below your gum line (DON’T!), there’s little chance that your trusty brush will ever make you sick.
The American Dental Association (ADA) reacted to the UAB study with several helpful reminders about toothbrushes, though. Among those gentle suggestions:
Rinse your toothbrush thoroughly after every use, and allow it to dry completely before reuse.
Store it properly. Toothbrushes should be stored in an upright position, not lying on any surface that can contaminate it. If you use a toothbrush holder, make sure the holder keeps toothbrushes separate. If toothbrushes touch, they can spread germs. And while we’re on holders, remember to keep the holder clean, as well. The National Sanitation Foundation recently found that toothbrush holders are the third-most germ-ridden household item behind only dish sponges and kitchen sinks.
Also, if you use a toothbrush cover, stop. Covering a wet toothbrush doesn’t allow the head to dry correctly. A damp, dark space is a nirvana for germ growth.
Disinfect, occasionally. You can keep germ and bacteria growth down by using any of several disinfectants on the market or soaking your brush in a glass of mouthwash for about 20 minutes.
Some people also try other methods, like nuking the germs in the microwave or running them through the dishwasher. Those are not great ideas, according to the ADA. Most toothbrushes are not made to withstand the rigors of that sort of treatment. Even if they retain their bristles, their effectiveness will likely diminish.
Don’t get too attached. You should change your brush or electric brush head every three to four months, the ADA advises. Some brushes have colored bristles to remind you when it’s time to change. When the color fades, it’s time for a new brush. Otherwise, make a habit to keep new brushes in your rotation. Also, ditch the old brush whenever you’ve been sick. Leftover bacteria and viruses can hide out in your toothbrush and reinfect you later.
Finally, common sense. No matter how well you take care of your teeth or toothbrush, frequent visits to a dentist (for you and the kids) are a good idea. Not only can they help you keep on track for oral health, but most will send you home with a new toothbrush in hand as well.
