I had the opposite experience. 9 cavities in my youth, and my brother had more. My two sons, 7 and 10, have perfect dental health. We are vegan and do eat less sweets than others, but it's not zero, and there is significant sugar in our diet. We've never used fluoride toothpaste but we have been very rigorous in teaching them how to properly floss and brush, and have almost never missed doing it. I would have thought something changed in the opposite direction in the last 30 years.
