Your toothbrush – what can you find on it?

21 September 2017

The dentists stress that replacing either your manual toothbrush or tips of the electric toothbrushes every 3 months is necessary. On the bristle, which enters our mouth at least twice a day, over a million bacteria and viruses can be found, entering our body regularly. Some of them can be really dangerous to us. What exactly can we find on the bristle of our toothbrush?

Fecal bacteria

If you’re keeping your toothbrush near your toilet or in a small bathroom, there’s a possibility that fecal bacteria will find their way onto the bristle. These bacteria can also be carried over through unwashed hands. These microbes can cause colon and stomach diseases along with poisonings. What’s even worse, there’s no way to remove them from your toothbrush.

Putrefying bacteria

Everytime we brush our teeth, a residue keeps building up on the bristle. The putrefying bacteria are created from food remains. We can get rid of them by scalding the toothbrush with a boiling water (the dentists recommend doing so once a month). In order to prevent development of of these bacteria, you should keep your toothbrush in a dry place, without storing it in any container.

Bacteria remaining after the illness

After every illness we had, it’s mandatory to replace our toothbrush, even if it was purchased recently. The bacteria from our mouth carry over to the bristle and can live on it without any problems. You should also replace your toothbrush after curing your teeth from cavities or if you had problems with mouth ulcers or cheilosis – failing to do so may result in the problems coming back.


Many viruses can easily survive on the toothbrush. Amongst them we can find the viruses causing HIV, HPV, flu, gastrointestinal diseases or hepatitis.

What to do in order to protect yourself from the diseases?

There are few simple rules which will allow you to reduce the amount of bacteria and viruses found on your toothbrush, along with avoiding some dangerous diseases.

  • Don’t buy the toothbrushes with natural bristle.
  • Remember to thoroughly wash your toothbrush after each brushing. Scalding it is also recommended, at least once a month.
  • Wash your hands before touching the toothbrush – the hands carry millions of bacteria which can easily remain on the toothbrush.
  • Don’t use someone else’s toothbrush, keep the heads of toothbrushes from touching one another.
  • If a toothbrush falls to the floor, sink or bathtub, wash it and scald it. If it falls in the toilet, throw it away immeidately.
  • If possible, keep the toothbrush away from the toilet.
  • Replace the manual toothbrush or brushing heads of the electric toothbrush every three months and after every illness.

Even if wet bristle is perfect for the development of bacteria and viruses, it’s pretty easy to reduce the amount of microorganisms on our toothbrush. Sticking to the basic rules of hygiene minimizes the risk of catching some disease.
