What to do to have a toothbrush without bacteria

You may have heard it at some time and you have not given it importance or you have not even stopped to think about it. However, what is certain is that your toothbrush has more bacteria than you think.

Toothbrushes contain an average of 10 million bacteria, among which are Escherichia coli or streptococci. This is due to the cross-contamination that can occur from both the mouth to the brush and the brush to the mouth. Step number 1. Go with your dentist in Tijuana to first verify that what does not have bacteria but your mouth.

On the one hand, we must not overlook the fact that the mouth is the part of the body that hosts more bacteria. This causes said microorganisms to be transferred from the oral cavity to the toothbrush. Also, most likely, like most people, keep your toothbrush in the bathroom. This is, apparently, the most logical and comfortable.

However, the bathroom is the place in the house where there is a greater amount of bacteria, which can end up in the toothbrush – and later in our mouth – in a very simple way. And is that every time we pull the toilet chain, intestinal bacteria or fecal germs are released into the air.

In addition, the chances of bacteria depositing on the bristles of the brush increase if we do not lower the lid when pulling the chain or if the bathroom does not have good ventilation.

There are some of the most common viruses and bacteria contagious through toothbrushes:


Influenza is an infectious disease that affects the respiratory tract and can resemble a common cold.

It usually presents symptoms such as sore throats, muscles, joints and headaches. In addition, it is common that these pains are accompanied by cough, malaise and fever. In its most serious version, the influenza virus can also lead to pneumonia.

Herpes simplex type 1:

Herpes is an infection that causes sores around the mouth or on the face. Although initially the herpes is manifested by a sore, it later becomes a blister that produces itching and pain.

In addition, it is noteworthy that the majority of people who have suffered from herpes have outbreaks several times a year.

E. coli:

E. coli is a bacterium that lives in the intestine of humans and some animals. There are many types of E.coli and, most of them, they are harmless.

However, some of the types of this bacteria cause stomach pains, vomiting and diarrhea.


Streptococci are a group of bacteria that are divided into two types: group A and B. Type A are those that are transmitted more frequently by the toothbrush and can cause infection in the throat, scarlet fever or impetigo.
