Ancient oral biome points to overall health

When a baby puts something from the floor in their mouth, we panic, but the mouth already contains thousands of bacteria. Now a team of researchers is looking at archaeological remains for an example of how Japanese oral biomes have changed and what they say about the people who owned those mouths and teeth.
