Since when does an anecdote provide any proof? I thought exactly the same things as your parent poster. Carbs are sugar, especially if you chew long enough. This affects teeth. Combine this with a lack of toothbrushes and a lack of fluoride and it sounds like a recipe for tooth decay.

Also, people didn’t live as long as they do now. So less chance to have your teeth rotten. Furthermore: the skeletons might have been of people in their twenties with arguably better teeth than old people.

Lots of questions that this anecdote doesn’t answer and you dismiss critique as pretentious.
