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.
Ever since I heard of microplastic, this has been on my mind quite a bit. Although it might not be "ingested" if they are micro enough, it can probably still get absorbed every time you brush. Multiple that by every day of your life and, boom, now there's plastic in my balls and I'm 3D printing on my girl's face.

This is a clever answer and now I completely agree with you.
I bought a uv tooth brush sterilizer. Not sure if it's doing anything useful but it's a colourful addition to the bathroom.
UV is good at breaking down plastics β¦.
In theory, your toothbrush is getting a clean twice a day. Its already covered in nice sudsy toothpaste foam and you'll (hopefully) be rubbing and rinsing that off.
The plastic disintegrating in your mouth however, yeah, I can't dispute that!
This is probably why dentists recommend replacing them frequently.
