Seriously I'd love to know but just can't bring myself to ask friends or even one person to their face, so how do I know? I know people that when I speak to them I can smell their breath a mile off and I find it vile, but what if my breaths like that and noone has told me? I brush my teeth properly twice a day and Actually just thought pretty sure my kids would tell me lol, but things that make me wonder are-i don't floss nearly as often as I should, and when I do I know there's a certain part I can't get the toothbrush into that I do smell (gross I know) but would this make my breath smell to others? Anyway I can find out without asking?
