For the first time ever my girlfriend says my breath smells like cigarettes. I do NOT smoke, I have good hygiene and I see my dentist regularly. I do however drink about 3-4 cups of coffee daily. Is this the reason why my breath smells like cigarette smoke or could there be some other reason? She also says that my breath doesn't smell like cigarette smoke even when we are face to face but only when we kiss does she smell the cigarettes.
