ELI5 Why do so many people get their wisdom teeth removed nowadays as opposed to ancient times? What changed?

Long story short, our hunter-gatherer ancestors had stronger and larger jaws, as their diet - raw flesh, plant roots, etc. - required much more chewing than our modern diet does.

As our jaws grew smaller, the total amount of teeth they were supposed to house sadly did not, causing the originally useful wisdom teeth to become a serious issue for many people.
