I live and work in the US. The American Dental Association recommends brushing twice a day. There doesn't seem to be any benefit to brushing three times a day.

I live and work in the US. The American Dental Association recommends brushing twice a day. There doesn't seem to be any benefit to brushing three times a day. I brush my teeth before I leave for work and before I go to bed. To carry or keep an extra toothbrush and toothpaste just so I can brush at work for no real benefit doesn't make sense. If my breath needs freshening, I can have a mint or chewing gum.
