What is bad breath?
Bad breath is a common symptom of poor oral hygiene, eating certain foods, using tobacco products, or even dry mouth. The medical term for bad breath is halitosis. Bad breath results from sulfur compounds released by bacteria in the mouth, breath odors, or salivary gland dysfunction.
Mouth Problems Spotlight
Poor oral hygiene is a common cause of bad breath. Without brushing and flossing daily, food particles remain in the mouth, tongue, and between the teeth. These food particles collect bacteria, causing bad breath. Infections of the gums (gingivitis) and salivary glands can both result in bad breath. Other common causes include dry mouth and smoking or chewing tobacco.
Certain medical disorders can cause bad breath, such as sinusitis and bronchitis. Gastrointestinal disorders may result in breath that smells like feces; this may indicate a bowel obstruction. Breath with a fruity odor may be a sign of diabetic ketoacidosis, a potentially life-threatening condition. Liver failure may be indicated if breath has an ammonia-like odor.
Bad breath alone is rarely a result of a serious problem. However, you should seek immediate medical care (call 911) if you experience bad breath along with other serious symptoms, such as high fever (higher than 101 degrees Fahrenheit), difficulty breathing, or prolonged vomiting.
If your bad breath is persistent or causes you concern, seek prompt medical care.
