A toothbrush can harbor up to 12 million bacteria. Discover the natural tip validated by dentists to keep it healthy.
The figures are clear: on average, the French change their toothbrush once and a half a year, while dentists recommend changing them four times a year. However, a toothbrush very quickly becomes a veritable nest of microbes. In just one week, especially if you have been sick (cold, flu, sore throat), bacteria multiply quickly.
According to Marc Kevin Zinn, microbiologist at the Rhine Waal University of Applied Sciences in Germany, interviewed by the BBC, a toothbrush harbors between 1 and 12 million bacteria, but also fungi and viruses. With water, saliva and food residue, microbes find something to grow easily. Result: with each brushing, some of these germs return to the mouth, potentially impacting not only your teeth, but also your general health.
While changing your toothbrush regularly is essential, there is also a natural method to keep it clean and healthy until replacement. Simple, economical and validated by dentists, it is based on an ingredient that many already use to maintain their homes: baking soda. To clean and disinfect your toothbrush, Le Courrier du dentist recommends the following recipe: in a glass of lukewarm water, add a teaspoon of baking soda, then soak the head of the brush for 15 to 30 minutes. Then rinse thoroughly with clean water and let air dry. This operation must be repeated approximately once a week. This reflex prevents the proliferation of microbes, does not damage the hair and leaves no unpleasant taste. Good news: this tip also works for electric toothbrush tips.
For an even more disinfectant action, you can add a few drops of white vinegar to your mixture. And if the brush is more than three months old or has worn bristles, it is better to replace it. Finally, for optimal lifespan, always keep your brush head upwards, without a cap – as it retains humidity – and above all away from the toilet to avoid any contamination.
Changing your toothbrush more often and maintaining it regularly is a simple but essential action to preserve the health of your mouth… and your entire body.
