Most of us use toothbrush twice a day without thinking, as soon as we wake up in the morning and before sleeping at night, we think that this will keep our teeth clean and healthy, but have you ever thought that the thing with which you are cleaning your teeth is itself clean. In fact, your toothbrush can become a small germ park, where millions of bacteria, viruses and fungus can be hidden. All this reaches your mouth, hands, and even from the bathroom environment to the toothbrush and continues to grow there. Every time you brush your teeth, you leave your saliva, bacteria, food and micro skin cells on the brush, and if your brush is kept in the bathroom, especially near the toilet, flushing can add more germs to it through airborne micro droplets. In such a situation, let us know when the toothbrush should be changed to avoid bacteria hidden in the toothbrush.
Where do bacteria come from on toothbrushes?
There are three main sources of micro germs found on toothbrushes. In which the first one is your mouth. Every time you brush, oral bacteria accumulate in the toothbrush. After this the second reason is skin and hands. Germs can stick to the brush while holding it and washing it. The environment of the bathroom can also be the reason for this. Germs spread in the air especially while flushing the toilet. Some scientific studies have even found that even a brand new toothbrush can be infected with bacteria even before it is sold in the market.
When should the toothbrush be changed to avoid bacteria hidden in the toothbrush?
According to the American Dental Association, toothbrush should be changed once every 3 months. If the bristles of the brush have become worn or spread, then replace them even before that. After falling ill, such as cold or flu, definitely change the toothbrush. Small children or people with weak immunity should change the brush every 6 to 8 weeks.
How to keep toothbrush clean?
After every use, wash the brush thoroughly with clean water, keep the brush upright and let it dry in the open air, never keep the toothbrush covered or in a closed box, this can cause bacteria to grow due to moisture. Keep more than one brush away from each other, so that they do not touch each other. Keep the brush at least 2 meters away from the toilet. Soak the toothbrush in antiseptic mouthwash for 5-10 minutes 1-2 times a week. If you want, keep it in 1 percent vinegar solution for some time, but wash it thoroughly later. Putting the brush in the microwave or dishwasher is one option, but this can damage the bristles. Some scientists are now developing toothpastes or toothbrushes that promote good bacteria.
