More than $500 million is spent in the U.S. on breath mints, gums, mouthwashes and toothpaste, yet halitosis (bad breath) affects almost everyone at one time or another. Breath mints and gums cover breath odors for a short time. Mouthwashes can help to clean the mouth and remove plaque by getting to those hard-to-reach places between teeth and at the gumline.

Thorough oral healthcare that combats the bacteria that causes the problem will cure your "dragon breath." The human mouth serves as host to more than 200 different types of bacteria, according to experts. Your tongue, palate and, to a lesser degree, your cheeks harbor bacteria. Regular brushing and flossing should alleviate halitosis.

Your tongue is a primary growth location for microorganisms. So don't forget to brush your tongue as well as your teeth. Missing a meal can also cause bad breath. Saliva decreases because of lack of chewing. Consequently, the breakdown products of foods and proteins previously eaten are exhaled, creating an unpleasant odor.

Bad breath may also indicate periodontal (gum) disease. If you do not clean your entire mouth, including teeth, gums and tongue, the palque can spread under the gumline creating pockets between the teeth and gums. Bacteria accumualtes in pockets and breaks down protein and dead cells, which causes an offensive odor. Of course there are some foods, such as garlic and onions, which stay on your breath for up to 24 hours. Even the most vigorous brushing and flossing will not eliminate "garlic breath."

Anything that dries the mouth - medications, stress, breathing through the mouth during exercise, fever - will cause bad breath. Saliva is a natural remedy for bad breath. Normal amounts of oxygen-rich saliva prevent bacteria from accumulating. Bad breath can also be attributed to a medical condition. A fruity smell may indicate diabetes. Some types of liver disease produce a sweet smell. Postnasal drip from a cold or sinus infection, chronic bronchitis and respiratory tract infections also induce bad breath. Whatever the cause, regular dental visits are necessary if you want to be rid of "dragon breath."
