Toothbrush. In one hand it scrubs food and gunk away and helps distribute fluoride toothpaste around. On the other itβs made of tiny plastic bristles that are probably disintegrating when in your mouth and growing a fun ecosystem when out of it.
the number of things growing on your toothbrush is definitely non zero but being frequently scrubbed in sodium fluoride probably inhibits a good portion of it\
related though, electronic toothbrushes are way, way better in terms of tooth care, and my understanding the last time I read through marketing bullshit a few years ago was that the rotational/mechanical ones were better than the ones that just vibrate i.e. Oral B vs Sonicare, but the fucking Oral B toothbrush heads have fucking exposed bits of the mechanism, like, there's these holes in it, so like, guess what? mold grows in there
I don't understand how that isn't like, you know, a massive design flaw that should be changed immediately, but I guess they want people to swap toothbrushes more often than mold would grow, idk
A bit of advice from some dental organizations and my family member who is a dentist, you really shouldn't use the same toothbrush twice a day. The toothbrush should be left to completely dry out before reusing and that takes longer than 16 hours in most climates.
