Same here. I am going to disassemble the cheap pepper grinders I recently bought to make sure there is no plastic in the grinding operation.

I switched to bamboo toothbrushes from plastic a while ago, before de-plasticizing was really a thing. Now I'm glad I did, because plastic bristles grinding against my teeth seems like an easy way for plastic to get inside my body. The bamboo toothbrushes are pretty nice too, the bristles are soft but firm, and the handle is made of bamboo too.

Personally, I spit out whatever happens when I brush my teeth. But bamboo does sound like a more pleasant experience all the way around.

All disposable grinders are going to be plastic, and likely none of the refillable ones will be since the plastic burrs only last one usage before they are all chipped off in to your food.

Mentioned elsewhere too but Peugeot (yes the car company) has been making top quality affordable pepper grinders for over a century.

The simple wooden ones last a decade or longer and cost about 35 $/€/£

Your teeth seem pretty hard though, to the point that a specialist has to go over them with metal tools every year to clean them.

and... plastic is not that hard, so the teeth should be able to grind down the plastic bristles as you brush your teeth. I'd find it hard to believe that no plastic is lost during brushing of teeth.

The idea of brushing my teeth with plastic has lost its appeal for me and will never be recovered.
