There's a recent podcast edition of Science Vs. about this very thing.
According to their interviewed experts and their research, brushing your teeth does nothing to prevent cavities UNLESS it's fluoridated toothpaste.
Flossing also doesn't really prevent cavities, but it is important for me gum health. They recommend regular flossing (more than once a week)
Born in the 80-ies I had several cavities before I was 15. Nothing helped, then one day the doc applied fluoride to my teeth directly and I spent a lot of less time at the dentist since then.
Using toothpaste with fluoride from them on made a massive difference.
