When Did We Start Getting Cavities?

The video explores the history and causes of tooth decay, focusing on the role of bacteria and diet. It explains how cavities form due to bacteria like Streptococcus mutants, which thrive on sugars and starches. The agricultural revolution marked a significant increase in cavities due to dietary changes. Historical evidence shows varying cavity rates in ancient populations, influenced by their diets. The evolution of cavity-causing bacteria is linked to human dietary shifts, with modern implications for dental health.

What evidence suggests that ancient humans had fewer cavities than modern humans?

In what ways has the genetic diversity of cavity-causing bacteria changed over time?

Why is it important to understand the history of tooth decay in humans?
