People can work up to eating fairly large shards of glass. Eating tiny bits of ceramic occasionally are unlikely to be an actual issue any more than ingesting a little bit of sand.
Glass eating is a real thing with a surprising number of documented cases. In some cases it’s classified as Hyalophagia a form of Pica where people focus on glass, but it doesn’t necessarily have significant negative side effects. https://en.wikipedia.org/wiki/Pica_(disorder)
There’s also a magic trick where people eat sugar that’s very clear and looks like glass, but that’s a different thing.
No, I’m saying some mentally ill people consume vast quantities of glass and medical professionals are only concerned with the most extreme cases. It’s like saying the forces involved in a boxing match are a useful benchmark for brain trauma, on that scale a 6 month old infant punching you is so far below that benchmark you don’t need to worry about it.
Which means if you’re worried about consuming 1/100,000th as much it’s clearly not a big deal.
