Fossilized dental plaque, or dental calculus, is a rich archive of ancient health information. Researchers have discovered that this substance preserves DNA and proteins from bacteria, diet, and the human immune system, sometimes in quantities up to 600 milligrams on ancient teeth. By studying these traces, scientists can reconstruct the dynamic interplay of diet, infection, and immunity over thousands of years. This approach moves beyond bones and mummies, offering a new window into the evolutionary roots of modern disease.
