Is Your Toothbrush Dangerous?

July 2014

We wash our clothes, we change the oil in our cars, and we keep the dust off of our furniture. But how many of us show any TLC to one of the most important hygiene items in the house – our toothbrush?

Legend has it that a dog’s mouth is cleaner than a human’s. And, while that is only true in severe cases, our mouths, and therefore our toothbrushes, do harbor all kinds of bugs.

"The oral cavity is home to hundreds of different types of microorganisms, which can be transferred to a toothbrush during use," said Dr. Maria L. Geisinger, assistant professor of periodontology in the School of Dentistry at the University of Alabama at Birmingham.

Here are some recommendations to make sure your toothbrush is safe to you and those around you:

• Don't share toothbrushes and store different family members' toothbrushes at least an inch apart.
• Rinse thoroughly after using.
• Allow toothbrush to air dry after each use, preferably in an upright position. This will keep bacteria from breeding. Don't store in a small, moist, closed container.
• Replace your toothbrush after having a cold or the flu.
• If you have a compromised immune system, rinse your mouth with an antibacterial mouthwash before you clean your teeth. This can reduce the germs passed to your toothbrush.
• Get a new toothbrush every 3 to 4 months or more frequently if you notice the bristles breaking down. While this won't reduce bacteria, it will ensure the best cleaning power.

And if that’s not enough, here’s one more thing for the list: Keep your toothbrush as far from the toilet as possible, or you may be brushing with something you don’t want!

"If you have your toothbrush too close to the toilet," microbiologist Charles Gerba, PhD, explains, "you are brushing your teeth with what’s in your toilet!” He explains that when you flush with the lid open, contaminated water vapor settles on surfaces in your bathroom, toothbrush included.
