I thought Egyptians had bad teeth because their flour was ground with sandstone, leaving sand in their bread. They ground their teeth into nothing by eating sand.

I feel like the sand thing was a guess by people who couldn’t pick why ancient Egyptians had worse teeth than everyone else in the ancient world
If there’s sand in your food you notice and it feels bad. It’s not something that makes you go “oh well I’ll just keep chomping” and that would wear teeth down, not give them abscesses
