Why Ancient Humans May Have Had Better Teeth

Why do ancient jaws often look roomier than modern mouths, even without toothbrushes or braces? This video explains how chewing, agriculture, sugar, and soft modern food changed human teeth faster than evolution could keep up. Ancient humans did not have perfect teeth. They had worn teeth, cracked teeth, infections, and plenty of painful problems. But in some ways, especially jaw space and lower cavity rates in many hunter-gatherer groups, their mouths may have fit their world better than ours fit ours. We’ll look at why tougher food helped shape growing jaws, how farming changed oral bacteria, why refined sugar made decay more common, and why modern dentistry is partly a patch for a mismatch civilization created. What do you think is the strangest modern thing we ask our ancient bodies to handle? Leave a comment below.
