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?
Some of us are sensitive to SLS, (the micro-abrations they create in the gums cause canker sores in some people), and it’s not easy finding a toothpaste that has flouride but doesn’t have SLS, so i buy the natural stuff then have a separate flouride rinse I use.
