That's because those fossils had way less access to sugar, which is the main reason we need so much more dental hygiene nowadays.

You all think sugar causes tooth decay, no, sorry. It's lipids. Not all bacteria use glucose, most use fatty acids for energy.

It is more probably that the sugar throws off lipid metabolic and that changes the oral microbiome.
