Many people have dental problems, but they say they brush their teeth every day, and some people brush their teeth twice a day. Why do you still have toothache and worm teeth? Because in the daily life you have not done a good job in dental care. So do you know how often children’s toothbrushes are changed? Let's take a look at the answers to the questions together.

How often do children's toothbrushes change
Generally speaking, for domestic toothbrushes currently on the market, the toothbrush bristles will be bent after using for 1-3 miyezi. The curved toothbrush bristles not only can not clean the food debris in the teeth, but also scratch the gums. Therefore, when you find that the toothbrush bristles are bent, you should immediately replace with a new toothbrush. In addition, the toothbrush heads that are used for a long time are likely to retain bacteria. Therefore, it is generally recommended to replace the toothbrush at least every three months. According to the actual situation, the deformation of toothbrush bristles and the frequency/day of brushing are used as degrees.

According to the American medical experiments, some patients with long-term throat diseases, if they replace a new toothbrush every few weeks, have a significant improvement in their condition. Toothbrushes continue to use for more than two months will breed bacteria, such as hemolytic streptococcus, lung cancer bacilli, candida albicans and gluconococcus. These bacteria can easily cause diseases such as pharyngitis and acute tonsillitis. People with weak immune systems may also have rheumatic fever and acute glomerulonephritis. So after brushing your teeth, be sure to rinse the toothbrush clean and put it in a dry place.
