What bacteria live in a used toothbrush?

The toothbrush you use to clean your mouth is full of germs, according to researchers at the University of Manchester in England. The uncovered toothbrush that we leave on the sink every day contains more than 100 million bacteria, including E. coli, the bacteria that cause diarrhea, and staphylococcus bacteria, which cause skin infections.
Don’t panic, the mouth is not sterile, of course. Hundreds of microbes live in our mouths every day. Problems arise only when there is an unhealthy balance of bacteria in the mouth. That is why it is necessary to clean the plaque that accumulates on the teeth every day.

Can a toothbrush make us sick?

Probably not. Regardless of how many bacteria live in your mouth or have been transferred there directly from your toothbrush, your body’s natural defenses make it very unlikely that you will get an infection simply from brushing your teeth.

Be careful where you leave your toothbrush and how you store it!

In many homes, bathrooms are small and the sink is located close to the toilet, where it is known that bacteria are “sprayed” into the air every time the water is turned on. Therefore, it is important that the toothbrush is not left uncovered near the toilet. It is essential to wash your hands before cleaning your teeth. An American dentist says: “Just as you put away and store your plates and cups, do the same with your toothbrush—if necessary, outside the bathroom.”

Tips on how to store your toothbrush.

Always wash your toothbrush thoroughly with running water before use. Allow it to dry, as bacteria thrive in moist environments. Do not cover the toothbrush with a cap, as this prevents it from drying properly. Keep it upright, without leaning against or touching another toothbrush, as germs can be transferred between the two brushes. Never use your spouse’s, brother’s, sister’s, or roommate’s toothbrush.

Can I use disinfectants and are they effective?

There are various products on the market that destroy bacteria with ultraviolet light in the form of a spray or water. Some toothbrushes have antibacterial bristles.
Some of these methods are effective, with no evidence that using disinfectant will reduce the risk of disease. Even the most effective method will not destroy all microbes. If you decide to use any of these methods, check for the SBS seal of approval.

When should I throw away my toothbrush?

It is recommended that you replace your toothbrush every 3-4 months. If the bristles on the brush are damaged or you have a weak immune system, replace it before this time. If you use an electric toothbrush, replace the head as often as you would a disposable toothbrush. Whenever you decide to skip your daily cleaning, think about how many bacteria are in your mouth right now that cause gum disease, tooth decay, and bad breath.
