Desk Employees: Developers, designers, others: do you brush your teeth at work?

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.

I try my best to brush and floss after a meal. Since I eat meals at work, likewise I'll brush and floss.

I have in the past, but for some years I've just kept good xylitol gum handy and chew most of the day, esp right after eating.
