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?
Please wait at least 30 mins before brushing after sugary and especially acidic things.
Why
Acid is still fresh on your teeth and you’re just scraping it into the enamel breaking it down. You should wait or at least swish some water around.
