…after eating snacks/lunch?
I keep a toothbrush and toothpaste in my cupboard at my desk. If I feel stinky, I go off to brush my teeth.
Otherwise, gum.
Water and gum.
I don’t drink coffee, so I get to smell everybody else’s nasty coffee breath. I don’t know if they notice it or not. So don’t drink coffee.
Toothbrush and mints.
Maintaining a strict 5 foot perimeter around myself. Especially after garlic.
Gum, mints, and brushing my teeth. The same things I’d do anywhere else.
I’ve got toothpaste and a toothbrush in a drawer with other grooming necessities like deodorant, razors, and shaving lotion.
Listerine breath strips.
I have quite the collection of Altoids handy at all times.
Sugar free gum, to be chewed after ingesting anything but water and tea.
