Not MINE, thank you very much! I'm not THAT stupid to use my OWN toothbrush when I'm cleaning the toilets. No sirreee sir!
Reminds me of the Seinfeld episode where Jerry accidentally drops GF's toothbrush into the toilet and then doesn't tell her, Jerry cannot bring himself to kiss his girlfriend, Jenna.
The plaque between your teeth harbors a huge culture of pathogens, which is a good reason to only use sodium bicarbonate to brush your teeth.
