How often do I change my toothbrush? Does it need to be changed every 3 months?


Everyone knows that toothbrushes cannot be used for a long time. Basically, they need to be changed every once in a while. Many people will change them every three months according to the written on the toothbrush. Does the toothbrush really need to be changed every three months? Can there be a set of rules that are not so rigid? Let's take a look at how often the toothbrush needs to be changed!
1. When the distance between the bristles of the toothbrush becomes larger
Usually the bristles are densely arranged. If the distance between the bristles becomes significantly wider, dirt will be more likely to remain on the root of the toothbrush, and it is best to replace it with a new one.
In addition, the toothbrush must be maintained at ordinary times. After brushing the teeth, the toothpaste and dirt on the toothbrush must be thoroughly washed. Put the toothbrush head up as much as possible after use. Staying dry will help reduce bacteria. The placement of the toothbrush should also be as dry as possible, because a humid environment is more conducive to the rapid reproduction of microorganisms.
2. The color of the root of the toothbrush becomes darker
The dirt on the roots of the bristles will accumulate slowly, which is one of the reasons for the growth of bacteria. Even if it is washed after each use, it cannot be completely prevented. Therefore, once the color of the root of the toothbrush becomes darker,
It is a signal of more dirt accumulation and should be replaced in time.
3. Toothbrush bristles are soft and collapsed
Once it is found that most of the bristles have soft and collapsed tips, it means that the wear degree is large and the teeth cannot be cleaned well, and they should be replaced.

It is recommended that the use period of the toothbrush should not exceed 3 months, but it also varies from person to person. For example, some people use the strongest force when brushing their teeth. In less than 3 months, the bristles of the toothbrush will bend and deform, and it must be replaced in time. Because the bristles are bent and deformed, the cleaning effect of the toothbrush is significantly reduced. At the same time, it is easy to cause damage to teeth and gums.
