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?
This, so much!
It really makes me angry, that there is no free dental hygiene training for children/teenagers.
I life in a comparatively rich society (Germany), but our removed health care system pumps billions every year in preventable diseases (like most dental problems) and exactly zero in prophylaxes.
