How To Disinfect A Toothbrush

How To Disinfect A ToothbrushAccording to the dentist’s bacterial culture of the used toothbrush, the new toothbrush contains a variety of bacteria such as Candida albicans and Streptococcus hemolytic after four weeks of continuous use.

These bacteria can enter various organs through blood vessels and lymphatic vessels, causing multiple diseases such as thrush, acute tonsillitis, pharyngitis, rheumatic fever, acute glomerulonephritis, and the like.

This is a potential threat to good health. Therefore, it is necessary to disinfect the toothbrush regularly.

Disinfection method for the toothbrush:

1, Alternate use. According to scientific studies, certain pathogenic bacteria can die on their own after being fully exposed to air for one week. This requires two toothbrushes to be used alternately for one week.

2. After each brushing, apply a layer of soap with high-efficiency bactericidal properties to the toothbrush.

3. Soak with 0.1% fresh clean or 0.1% to 0.5% peracetic acid or Or baking.

First, find a clean cup and pour the right amount of warm water in the bowl (the water temperature is about 40°, the water depth should be able to flow over the entire toothbrush head).

Then use a small spoon to take a teaspoon of baking soda powder, pour it in a cup filled with warm water, and gently stir with chopsticks until the baking soda powder is completely dissolved in the water.

Next, soak the used toothbrush into the cup. The soaking time is about 20 minutes. Make sure the entire toothbrush head is immersed in the cup.

When the time is up, pick up the toothbrush and rinse it under the tap until it is rinsed out, so that the disinfection of the toothbrush is complete.


Don’t leave the toothbrush in the bathroom, especially near the toilet. Because the bacteria are particularly easy to fall on the toothbrush when the toilet is flushing,

So if there is a small cupboard in the bathroom, please put the toothbrush in the closet. If not, try to stay away from the toilet.

But if your toothbrush has the following three signals, it means the toothbrush should be changed.

1. The root color of the toothbrush becomes darker

The dirt on the roots of the bristles accumulates slowly, which is one of the causes of bacterial growth, even if it is not entirely prevented after each use.

Therefore, once the root color of the toothbrush is found to be darker, it is a signal that the dirt accumulates more and should be replaced in time.

2. The tip of the toothbrush is soft and collapsed

Once most of the bristle tips are found to have a soft collapse, the wear is substantial, and the teeth are not cleaned properly and should be replaced.

3, the distance between the bristles becomes larger

Usually, the bristles are arranged in a dense arrangement. If the gap between the bristles is significantly widened, the dirt is more likely to leave the root of the toothbrush, and it is better to replace it with a new one.
