I've only been brushing my teeth before bed for like 6 years at this point, and flossing once a week or so. I don't know if it's the fluoride alcohol mouth wash I use or just dumb luck, but I haven't gotten any cavities

So I think that given this rigorous scientific data, you can safely avoid brushing for the most part

It's complicated. There's definitely a genetic component to having hard teeth.

A lot of it is diet too. Not eating or drinking sugary things gives you much more room for error. Of course you still need to brush and floss, but in my experience sugar + rigorous cleaning can still leave you with cavities whereas no sugar + lax cleaning you're probably fine. No sugar + rigorous cleaning and you might never need a dentist again. It took me way too long to understand this.

fwiw, I have pretty bad teeth (~10K for crowns etc a few years ago).

And I switched to only brushing with an electric toothbrush before bed, and don't really floss and think I've only had one small cavity since then and the hygienist said my teeth looked quite good in general.

Worth noting that I have a good diet and rarely eat sugar beyond yogurt.
