There are two kinds of people in the world. The type that keeps the toothbrush in an open place, in a latrine-filled toilet (large, right?) And the type that does not use a toothbrush, even if it is difficult to cover from time to time, should be disinfected in a dishwasher or a beautiful UV sterilizer. Do you know who of the two groups is following the CDC and ADA toothbrush care guidelines? Surprisingly, these are lazy.

But aren’t their toothbrushes covered with bacteria and other small microbes? They definitely are. everything Toothbrushes are full of germs and most of them come out of our mouths. This is a review of studies on toothbrush contamination All of them report that “after use, they found significant retention and survival of bacteria in toothbrushes.”

Toothbrushes start with germs (because they are factory-clean but not sterile) and quickly remove any germs in your mouth. If you have any germs in your mouth (toothache, cold) will be Get in your toothbrush and you won’t be able to remove them completely. Here’s an interesting fact: As toothbrushes get older, their surfaces wear out and they are able to retain their teeth. more microbial.

You will not die from toothbrush germs

Before we go any further, let’s be clear: the idea of ​​germs in your toothbrush can swallow you, but it does not pose a threat to most people’s health. This was reported by the CDC People with bleeding or immunosuppression may need to find other ways to take care of their mouth, and if this is you, talk to your doctor. For the rest: “Centers for Disease Control and Prevention are unaware of the health effects directly related to the use of toothbrushes.”

Dry your toothbrush

The best way to fight all these germs? And according to the CDC American Dental AssociationAir drying is key.

After brushing, rinse your toothbrush with tap water. It does not kill bacteria, but removes toothpaste or other contaminants that can interfere with the drying process. Place your toothbrush vertically and place it in the holder to air dry. Drying the bacteria prevents them from multiplying. Used toothbrushes can be stored in a container or covered with a lid to inspire bacterial growth. The few germs you don’t store are more than the ones you’re celebrating.

For more information on proper toothbrush care:

  • Do not share toothbrushes; Keep body fluids to yourself.
  • For the same reason, do not let your toothbrush touch anyone else’s toothbrush.
  • Replace your toothbrush when it is worn out or every three to four months. Toothbrushes clean your teeth best (and less bacteria) when they are in good condition.

If the thought of bacteria swallows you so much, you will feel it need to If you do something about it, the ADA says you can soak your toothbrush in Listing or 3% hydrogen peroxide (something you get from a brown bottle at the drugstore). It does not kill all bacteria, but can reduce levels by 85%. (Now, 85% of a bacilli are still bacilli, but that may make you feel better.)

Do not put your toothbrush in the dishwasher or microwave; It can kill bacteria, but it can also damage your toothbrush. Experts seem to be divided on ultraviolet (UV) sterilizers. The CDC says they can “damage” toothbrushes; The ADA acknowledges their existence but does not make recommendations for or against them.

So do I have dung on my toothbrush or not?

So what about toilet plumes? It is true that toilets release droplets into the airsome of them may turn into aerosols, float around the room, and eventually fall on your toothbrush or other objects.

However, there are no studies that directly link toilet sprays to toothbrushes. Instead, there are studies like ours this dissertation Traces of fecal bacteria were found in 60% of toothbrushes stored in communal bathrooms (an average of nine people shared a bath). However, there was no control group in this study; This is not a comparison of toothbrushes stored in the bathroom with toothbrushes stored elsewhere, it is just a study of toothbrushes. (Bacteria have also been identified more mouthwash is common in toothbrushes, which indicates that mouthwashing is not the best way to reduce your hermophobia.)

On the other hand, the microbiome project listed the microbes found in the toothbrushes of volunteers across the country and found no clear evidence that the toothbrushes were colonized by fecal bacteria. (Previous studies, including the dissertation, have used methods that do not accurately predict the origin of microbes in dung, which appear to belong to the same family as normal dung microbes.) awning Gizmodo.

Whether your toothbrush contains germs or not, we have found that it is better to dry the germs than to incubate them in a closed container. You can store your toothbrush in another room if you wish, but beware of hidden sources of germs. that a room.
