I suppose if people told me I had bad breath, I might think about it more, but no one does.

I don't usually eat Oreos, but following your line of thinking, I do get food stuck in my teeth. About 90% of the time, its in my molars and I'll work at it with my tongue as long as I can. If absolutely necessary I'll dig it out with a finger (but not in public). On those occassions where I have food stuck in the visible portion of my mouth, its like the bad breath...no one says anything and nothing gets done until I notice.
