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
So I searched it up. Food that was more abrasive, no refined carbs, more fibrous, more meat, less grain, more tannins. And ancient toothbrushes from frayed twigs, which also contained natural antimicrobials!

Thanks for prompting this educational exchange!
Also, for example in medieval times, they did clean teeth with herbs and stuff.
Ancient Babylon and Egyptians used frayed twig, according to my search!
