However the person probably doesn't know that it is something in there teeth. If they want you kiss them, and you want to kiss them back. If you are really into them just politely say, "sweeheart you have something between your teeth" say this before your kiss him. Let me tell you, we all come across the littlest things that make us look crazy at times. Really having something between are teeth it can happen to anybody. Yes I would kiss someone, but he would just have to remove the food particle from his teeth. That it.
