How to use a toothbrush scientifically, and what situations prompt the need to replace the toothbrush

What situations prompt the need to replace the toothbrush

The color of the bristles at the root becomes darker: The dirt at the root of the bristles will gradually accumulate, which is one of the reasons for bacterial growth. Even after cleaning after each use, it cannot be completely prevented. Therefore, once the color at the root of the toothbrush becomes darker, it is a signal of more dirt accumulation and should be replaced in a timely manner.

● Soft collapse of bristles: Once most of the bristle tips are found to have soft collapse, it indicates that the wear is high and the teeth cannot be cleaned well. It should be replaced.

● Widening of bristle distance: Usually, the bristles are densely arranged. If the distance between bristles significantly widens, dirt is more likely to remain at the root of the toothbrush, and it is best to replace the toothbrush with a new one.
