Dental caries on carnivore

We have seen in many studies of carnivore populations (Inuit, native Americans, African) that they have near zero dental cavities.

It's pretty clear that cavities are related to PBFs/carbs/sugar.

The whole debate around fluoride is a risk reward analysis, where the positive side is less cavities in children and the downsides are associative and hotly debated.

Seems the benefit that fluoride provides is only necessary because the standard diet promotes cavities, and a more human focused diet like carnivore is already protective and thus no need for fluoride.
