I saw in a documentary a couple years ago that skulls of our ancient hunter-gatherer ancestors had little to no dental cavities—their teeth were intact. It was attributed to their very diverse bacteria exposure (being hunter gatherers) and no sterilization. This changed with farming.
I'm a bigger fan of probiotic research rather than this antibacterial "arms race".
- maxerickson 9y agoThere's likely a gene variant where people that have it have much higher resistance to cavities (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3318028/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3318028/ ). It'd probably be more prevalent if we didn't cook food and needed our teeth more.
- shagie 9y agoThis has more to do with sugar (corn in the americas). For example, in Wisconsin it is possible to use dental information to identify if there was a diet of wild rice or corn. https://www.wpr.org/shows/wisconsins-mound-builders https://www.wpr.org/shows/wisconsins-mound-builders Farming is in part responsible for the concentration of sugars that bacteria use.
