Only daily brushing and flossing, and scheduling regular professional cleanings, will take care of unpleasant breath. And don't forget your often overlooked tongue as a culprit for bad breath. Bacterial plaque and food debris also can accumulate on the back of the tongue. The tongue's surface is extremely rough and bacteria can accumulate easily in the cracks and crevices.
If you have constant bad breath, make a list of the foods you eat and any medications you take. Some medications may contribute to bad breath.
Improperly cleaned dentures can also harbor odor-causing bacteria and food particles. If you wear removable dentures, take them out at night and clean them thoroughly before replacing them.
If your dentist determines that your mouth is healthy and that the odor is not oral in nature, you may be referred to your family physician or to a specialist to determine the cause of the odor and for treatment. If the odor is due to gum disease, your dentist can either treat the disease or refer you to a periodontist, a specialist in treating gum tissues. Gum disease can cause gum tissues to pull away from the teeth and form pockets. When these pockets are deep, only a professional periodontal cleaning can remove the bacteria and plaque that accumulate.
Mouthwashes are generally ineffective on bad breath. If your bad breath persists even after good oral hygiene, there are special products your dentist may prescribe, including "Zytex," which is a combination of zinc chloride, thymol and eucalyptus oil that neutralizes the sulfur compounds and kills the bacteria that causes them. In addition, a special anti-microbial mouth rinse may be prescribed. Some antiseptic mouth rinses have been accepted by the American Dental Association for their breath freshening properties and therapeutic benefits in reducing plaque and gingivitis. Instead of simply masking breath odor, these products have been demonstrated to kill the germs that cause bad breath. Ask your dentist about trying some of these products.
