We all know that if you use a Toothbrush for too long, it will not only fail to clean your teeth but it will also damage your teeth. According to many studies, the toothbrush replacement in March is the most scientific, but if you simply change the date of your toothbrush, you may be too rigid. And, if your toothbrush has these phenomena, you have to change it even if you don't have time.
(Why should the toothbrush change frequently? How long does it take to change health?)
Why change your toothbrush?
Although the toothbrush is an everyday item and it is used in the mouth, it should not be too dirty. But the result was surprising. Some people experimented with bacteria on the toothbrush. After taking 10 used toothbrushes for overnight cultivation, they all detected bacteria, one less and many more than a thousand. Not only are there bacteria, bacilli, fungi, but also individual test samples found in these bacteria. When these bacteria reach a certain amount, they will cause infection in the oral cavity. It is clear that the growth of these bacteria is directly proportional to the life cycle. Therefore, we must always change the toothbrush in order to effectively prevent oral infections.
According to market research, toothbrushes are deformed after being used in the market for 1 to 3 months. After the deformation, not only can the food residue in the teeth not be brushed, but also the gums can be scraped. Therefore, experts recommend that the toothbrush should be changed every three months.
Three signals for toothbrush
Of course, under normal circumstances, if your toothbrush has these conditions, even if it has not been used for three months, you should immediately replace it.
1. The color of the toothbrush root becomes darker: the dirt on the roots of the bristles will slowly accumulate, which is one of the reasons that lead to the growth of bacteria. Even if the cleaning is not completely prevented after each use, the color of the root of the toothbrush is deepened, which is the accumulation of dirt. More signals should be replaced in time.
2. The tip of the toothbrush is softly collapsed: once it is found that most of the bristles have a soft collapse, it indicates that the degree of wear is large and the teeth cannot be cleaned well and should be replaced.
3, the distance between the bristles becomes larger: usually densely arranged between the bristles, if the distance between the bristles significantly widened, dirt is more likely to remain root of the toothbrush, it is best to change the new.
In addition, we must also maintain the toothbrush. After brushing our teeth, we must thoroughly clean the Toothpaste and dirt on the toothbrush. The toothbrush head after use is also put up as far as possible. Keeping it cool helps reduce bacteria. The placement of the toothbrush should also be as dry as possible because the moist environment is more conducive to the rapid propagation of microorganisms.
