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?
No, it’s not. I have never brushed my teeth too hard and have always used very soft toothbrushes, but I used to brush for 6-7 minutes, and my gums have suffered for it. Way too much of my teeth are now exposed, which is both ugly and causes sensitivity.
In the long run, if one keeps this up, teeth will start falling out.
Don’t overbrush.
I am sorry to read about your gum problems, fingers crossed it does not get worse!
