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
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.
No need to worry, we are all in the process of dying, so the correct answer is just to ignore everything that isn't either: something that strikes you as incredibly obvious (don't drink poison), recognized in its field of experts (high cholesterol is bad for you), established knowledge, or not too inconvenient.
> recognized in its field of experts (high cholesterol is bad for you)
Public service announcement: this one is controversial. IMHO it's wrong, based on bad science and agendas, and harmful because it deters people from nutritious foods. I recommend everyone do their own reading to form their own opinion.
It's sad how political food and nutrition is because it causes misinformation and malnutrition.
My rudimentary understanding: chronic high blood sugar causes irritation of blood vessels; irritated blood vessels attempt to protect themselves by producing a protective layer (excretion?); cholesterol sticks much more readily to this‚ causing creation of plaques. So, cholesterol is "fine" if you avoid high blood sugar.
