Put the toothbrush head up in the cup, because it is ventilated and dry to avoid breeding germs. The toothbrush is in a humid environment with its head down, which is easy to breed harmful bacteria. Bacteria in the mouth are generally attached to toothbrushes, and these bacteria can only die if they are planted in a dry environment. However, it takes 24 hours for the bristles of a toothbrush to completely dry. Therefore, it is recommended to prepare two toothbrushes alternately in the morning and evening. Change your toothbrush every other day.

P.S.: It is suggested that toothpaste should be placed in the cup face down, that is, the side with the lid facing down, because toothpaste can kill many bacteria in the cup.

Adoption. Oh, thank you
