Although halitosis (bad breath) usually is nothing more than a harmless reflection of what you've eaten, sometimes it's a sign of a serious dental or medical condition, the American Dental Association says.
Halitosis could indicate chronic bronchitis or sinusitis, postnasal drip, gastrointestinal illness, and liver or kidney disease, the ADA warns.
If watching the foods you eat and brushing and flossing regularly do not control halitosis, the ADA recommends talking to your dentist about any other conditions that may be responsible, including periodontal disease. If your dentist doesn't find a cause, you should talk with your doctor. – (HealthDayNews)
