Yours was the first sensible comment I came across.

While it's true the availability of fermentable carbohydrates in modern diets has contributed to the prevalence of dental caries, etc, it is mostly collective cultural amnesia to believe our ancestors had perfect teeth.

The concept of "tooth worms" existed for thousands of years prior to the advent of medical science. I'm on mobile, but I also recall reading about ancient remains (possibly pre-humans) with drilled cavities, woven metal bracings, and many other types of dental protheses.
