So. It turns out that before toothbrushes, dental floss, dental hygienists, 14 kinds of toothpaste and multiple varieties of mouthwash, our ancestors had better teeth than we did. This, from Andrew Sullivan’s blog: ”Hunter-gatherers had really good teeth,” says Alan Cooper, director of the Australian Centre for Ancient DNA. “[But] as soon as you get to farming populations, you see this massive change. Huge amounts of gum disease. And cavities start cropping up.” With farming came all sorts of grains and carbohydrates.
I guess Girl Scout cookies, whole wheat bread, Triscuits and popcorn hasn’t helped the situation.
