Are you sure about that? We lost so many teeth after the industrialisation of sugar production (machines and slavery) but I’m not sure how bad it was before then.
Teeth used to get cleaned by means of chewing harder food regularly, and they needed less cleaning to start with due to a lot less sugar in those foods though
