How often do I need to change my toothbrush?
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 should be maintained at ordinary times. After brushing the teeth, the toothpaste and dirt on the toothbrush should 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. This is one of the reasons that cause bacteria to grow. Even if you wash it after each use, it cannot be completely prevented. Therefore, once the color of the root of the toothbrush becomes darker, it is a signal that more dirt has accumulated, and it 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, so they 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.
