Bamboo toothbrush is a must-have in people's daily life, do you know how often it is better to change the toothbrush?
Share with you that when the following 3 signs appear, it means that your bamboo toothbrush should be replaced!
1. The tip of the toothbrush is soft and collapsed. Once most of the bristle tips are found to be soft and collapsed, it means that the wear degree is relatively large, and it is no longer able to clean the teeth well, so it should be replaced.
2. The distance between the bristles becomes larger. Usually, the bristles are densely arranged. If the distance between the bristles becomes significantly wider, the dirt will be more likely to remain on the root of the toothbrush. It is best to replace it with a new one.
3. The root of the toothbrush becomes darker. Dirt at the root of the toothbrush will slowly accumulate, which is one of the reasons for the growth of bacteria. Even washing after each use cannot completely prevent it. Therefore, once the root of the toothbrush becomes darker, it is a signal of more dirt accumulation, and it should be replaced in time .
