How clean is your toothbrush? Or rather, how dirty is your toothbrush?
A moist toothbrush sitting on a bathroom countertop is a breeding ground for bacteria, especially since a bathroom can be the most unclean room in a typical house. Those standard toothbrush holders where the brush sits upside down are basically the equivalent of your toothbrush yelling ”I’m over here” to all the bacteria floating around.
