[Escapado]

I usually eat 3 meals a day or two meals and a snack and I brush my teeth about 20-30 minutes after that so I guess it mostly due to my wish to get my mouth feel fresh and prevent staining if I had something like kimchi. 2 minutes twice per day is probably sufficient most of the time but the amount of abrasion and gum damage will probably also heavily depend on the hardness of the brush, the specific toothpaste and and the of course how vigorously you brush. I asked my dentist about this last year and he said it's fine and my gum health and enamel seem to confirm that.
