It is essential to take proper care of your toothbrush. You want to always rinse your toothbrush with water after brushing your teeth. Store your toothbrush upright, if possible, and allow it to air-dry until using it again. You want to avoid covering toothbrushes or storing them in closed containers routinely; doing so can encourage the growth of bacteria.

Why you don’t want to have your toothbrush in your bathroom:

There are several reasons why some people prefer to keep their toothbrush out of the bathroom. One reason is that flushing the toilet can release bacteria and germs into the air, potentially damaging your toothbrush. Additionally, if you share a bathroom with others, keeping your toothbrush open could increase the risk of cross-contamination. However, if you take proper care of your toothbrush and replace it every three to four months, it should be safe to use regardless of where you store it.
