Why Ancient Humans Had Perfect Teeth Without Dentists

Ancient humans had no toothbrushes, fluoride, braces, or dentists sending increasingly desperate appointment reminders. Yet many hunter-gatherer skeletons show fewer cavities and jaws with more room for their teeth than we often see today. So what happened? This video follows the changes inside the human mouth as our food became softer, easier to process, and richer in fermentable carbohydrates. Tougher diets placed more mechanical demand on growing jaws, while less frequent access to decay-friendly foods often gave cavity-causing bacteria fewer opportunities. After farming spread, jaw shape and oral health began changing—but the pattern was never as simple as “hunter-gatherers had good teeth and farmers had bad teeth.” ([PLOS][1]) Ancient teeth were also far from perfect. They could be worn almost flat, cracked, infected, and damaged by grit or years of being used as tools. And when toothache arrived, treatment might involve a sharpened piece of stone and the most confident person nearby. Recent research even reports evidence of invasive cavity treatment in a Neanderthal tooth from nearly 60,000 years ago. ([PLOS][2]) The real story is not that ancient humans had superior teeth. Their mouths were simply better matched to the food and chewing demands of their environment. We changed that environment much faster than the basic human mouth could change with it. #AncientHumans #HumanEvolution #Teeth #Archaeology #Science References *Jaw and tooth changes after the transition to agriculture* [https://journals.plos.org/plosone/art...](https://journals.plos.org/plosone/art...) *High cavity rates among Taforalt hunter-gatherers eating starchy wild plants* [https://www.pnas.org/doi/10.1073/pnas...](https://www.pnas.org/doi/10.1073/pnas...) *Ancient dental plaque and changes in the human oral microbiome* [https://pmc.ncbi.nlm.nih.gov/articles...](https://pmc.ncbi.nlm.nih.gov/articles...) *Ancient oral microbiomes during the transition to farming* [https://pmc.ncbi.nlm.nih.gov/articles...](https://pmc.ncbi.nlm.nih.gov/articles...) *Oral health among Hadza hunter-gatherers transitioning toward village life* [https://journals.plos.org/plosone/art...](https://journals.plos.org/plosone/art...) *Changes in chewing behaviour associated with increasingly processed food* [https://journals.plos.org/plosone/art...](https://journals.plos.org/plosone/art...) *Nearly 60,000-year-old evidence of invasive Neanderthal dental treatment* [https://journals.plos.org/plosone/art...](https://journals.plos.org/plosone/art...)
