    Why do we require unnatural substences such as tooth paste in order to keep our teeth from rotting and limiting our ability to feed properly? Why do we need so many unnatural things such as beds, clothes, and daily cleaning?

    i've wondered this too. my best guess is that as we grew more intelligent we developed things like hygiene and clothing. people that were easily infected, had weak feet, bad teeth etc continued to survive we became more and more dependent on our intelligence for survival and less dependent on our bodies

    because without these things we die younger and don't need our teeth to last as long as a result.

    in fact, tooth quality started coming down with the agricultural revolution, presumably due to lower quality nutrition - i'm not aware of any paleolithic or mesolithic hominid with cavities

    Yeah apparently cavities/ dental caries were seen from around the time we began farming (according to fossils) so there are theories that dental plaque bacteria are from some sort of zoonosis whether by transfer of a protein/of the entire bacteria changing species.

    I have to admit though know very little on this, I just heard it in a lecture.

    Well there had to be a point in human history where S. Mutans made the jump to being a commensal organism of the human mouth. I don't know if it happened in recent human history though.

    Well on the point of toothpaste I wonder too whether there doesn't already exist a natural method or substance that can be used in place. There is a tree whereby the branches contain a minty chemical that indeed does clean your teeth, I think for the health of our teeth we should be eating harder foods, it's healthy for the strength of our jaw muscles.
