Why do dentists always recommend to brush 2 times for 2-3 minutes? (lemmy.zip)

I almost always read in the news/press that dentists recommend to brush teeth two times a day for 2-3 minutes.

This drives me crazy, because it does not make sense; The point for dental health is to systematical clean every surface of your teeth twice a day (and use inter-dental brushes/floss once a day). For me, brushing my teeth takes around 6 minutes, if I hurry up. For someone faster it might be possible in 1 minute.

So, why do dentists always give the 2-3 minutes recommendation?

In case you are unaware current advice is to avoid brushing for a while after an acidic food or drink

"after every meal" does not mean "immediately after every meal"

Technically then I brush after every meal provided I don't die after eating

Guidance for preschools around me is for them to brush kids teeth after every meal that’s served at school.

That was recently reinstated after being suspended for a couple years and the teachers are practically (as much as they legally can) begging the parents to sign the waivers to opt their kids out of it. I don’t blame them. It seems excessive and it’d take a ton of time for two teachers to scrub a dozen or so sets of toddler teeth, while also controlling said toddlers while they wait for everyone to finish.
