11 Disgusting Things That Could Be On Your Toothbrush

Your toothbrush may look innocent sitting on your bathroom sink. But before you put it in your mouth, consider this – the average toothbrush can contain 10 million bacteria or more—including E.Coli and Staph. These terrifying facts we are revealed by researchers from the University of Manchester in England. You should know that your toothbrush is a little bacteria magnet, attracting the little buggers from several sources: if you store your toothbrush on or next to the bathroom sink, it gets contaminated from splashing from washing hands — and whatever you are washing off your hands is getting splashed back as well. And you will be thrilled if you know what happens when you flush with the toilet lid open: bacteria and viruses falling from toilet spray “remain airborne long enough to settle on surfaces throughout the bathroom.” An English study found that diarrhea-causing bacteria from a lidless flush flew as high as 10 inches above the toilet.

That’s how many microbes live on your toothbrush, among which these are the worst ones:

Unfortunately if your bathroom has a sink and a toilet in the same room and you keep flushing with a lid open, the splashes of the fecal spread within 5 or 6 foot radius. Meaning that such depositing bacteria as E.Coli goes straight onto your toothbrush, which you use every single day and make yourself sick. In order to avoid it, make sure you flush with a lid closed and wash your hands every time you use the bathroom and even before brushing your teeth.

Staphylococcus Aureus

This bacteria lives in your respiratory tract and on your skin as well. But in certain conditions it can be responsible for some nasty stuff, like necrotizing fasciitis, which is literally flesh-eating bacteria. Usually the bacteria can infect you through the open wound but luckily it is a very rare condition, which you still don’t want to be on your toothbrush.

Streptococcus Mutans

This bacteria is very common as it is responsible for the tooth decay. Keeping bacteria and other nasty stuff to a minimum on your toothbrush could be as simple as what you buy. According to one study, “Toothbrushes with lighter or clear bristles retain up to 50 percent less bacteria than colored toothbrush bristles,” Geisinger says, potentially because clear toothbrush bristles have less porosity than colored ones. And also opt for usual, solid plastic handles instead of the fancy rubber ones.

Food Debris

The leftovers from your last dinner can still rest on your toothbrush next morning. Therefore it is advised to always wash your toothbrush before putting it into your mouth with a warm water and some antibacterial mouth rinse.

Lactobacillus and Pseudomonas

These bacteria are responsible for pneumonia type infections, while Lactobacillus is usually a friendly like bacteria which is often present in our foods and guts. However it can be also linked to cavities and tooth decay. It usually likes the brushes with frayed bristles. So if you see that your toothbrush bristles look quite dead, it is better to change it now.

Herpes Simplex Type One

If a patient has an active herpes outbreak this bacteria can live on your toothbrush for a week. And if you tend to share toothbrushes with somebody, the possibility of getting an infection is rather high.

Another virus that can me a home from your toothbrush is Human papillomavirus. It is connected with cervical cancer and esophageal and oral cancers. But according to the studies the amount of this bacteria in your mouth can be reasonably low if you do a good job with tooth-brushing.

The bacteria is responsible for yeast infections and diaper rash, as well as it can cause the oral thrush, which is basically the yeast infection of your mouth. To make sure that candida doesn’t reside on your toothbrush and doesn’t go from one  to another, make sure you keep your brushes upright and quite away from each other.


This is he worst thing you can have on your toothbrush as it is a perfect condition for bacteria growth. Toothbrush needs around 24 hours to get totally dry, therefore having two of them would be perfect. Unless you use it once a day, and it stays dry with a minimum of bacteria flow.


The majority of adults have a destructive gum disease which makes blood getting on the toothbrush, so the bacteria can easily go into the bloodstream. Regular dentist check, cleaning and examination of your teeth means less blood in the saliva and less blood on the toothbrush!
