I chew gum all the time
Chewing gum is a great way of killing they horrible pungent smell in your mouth.
How it works is - you might have noticed that sometimes when you go to put something really yummy in your mouth like a nice juicy doughnut or your favourite cake or chocolate that you get this extra liquid (saliva) in your mouth. Well chewing gum works very similarly by chewing gum it produces more saliva and that saliva you eventually swallow the more you chew the more saliva you produce.
With that saliva going down your throat you are also getting rid of any build of bacteria which keep sthe smell away too. I Love chewing gum. Plus you have a fresh breath all the time.
