Your teeth, your gums, and your tongue have something in common. They all collect bacteria that can cause bad breath.
That's why you need a tongue scraper to remove 75% of those nasty lingering bacterial compounds. If you're still brushing your tongue with your toothbrush, you should know that it moves the bacteria around and only gets rids of 45% of the nasties.
A small investment and a few seconds of your time can make a difference in your life and the lives of those close to you. If your breath doesn't improve, see your dental professional for help. You might have gum disease.
