Toothbrush PNG

The toothbrush can be used for an average of 2 or 3 months. With regular use, the toothbrush gets old. This causes it to lose its old function and not be beneficial. The criterion of not providing benefit is that it cannot reach all teeth and the cleaning process is not performed. Of course, even if the toothbrush is not used regularly, bacteria can form in the area where it is located. Therefore, it must be changed after 4 months at the latest. In the process, the bristles of the toothbrush also bend and therefore need to be replaced.
