There could some health related problems that result in bad breath or it could be just that you have residue on your tongue. A friend of mine from India brought me back a tongue scraper from a trip to India. In India, they routinely use tongue scraper to remove the residue from the tongue. Most bad breath is illiminated using this. This is catching on in the US but slowly. It is worth a try. You will be surprised at what you find when you use it. I am not sure where you could find one..maybe on the internet or possibly the dentist(?). It should be fairly inexpensive. It looks like a thin stainless steel narrow horse shoe like thing. You simply hold it with both hand and gently scrap your entire tongue. As you become use to it, you will be able to scrap it a little harder to remove more. Good Luck. It is worth a try.
