Nothing in this article addressed tooth decay or dental formation issues.

Also from the article:

Hunter-gatherers who live until the age of 15 typically experience a lifespan of around 72 years. Among elderly hunter-gatherers, the incidence of diseases such as cancer and high blood pressure is very low. When recalculating the average lifespan excluding child mortality, the average lifespan for hunter-gatherers ranges from 68 to 78 years.

I also never said we shouldn’t follow science or modern medicine.

Dental health of hunter gathers looks like it was much better than ours:

“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.”

Additionally, they had better spacing due to eating tougher foods like high fiber items and tendons. So there’s less dental impacting like we have with wisdom teeth.
