bad breath

A generic term referring to unpleasant odours emanating from the mouth, the intensity of which differs according to the foods eaten, such as garlic, onions, red meat and fish. Other factors include obesity, smoking and alcohol consumption. It is generally worse upon awakening (“morning breath”) because the anaerobic bacteria in the mouth have had hours to proliferate and produce volatiles. Acute bad breath can be addressed by oral hygiene in the form of mouthwashes, brushing the teeth and tongue, flossing, and use of inter-dental brushes. Chronic bad breath affects up to 25% of the population and may be socially or professionally crippling, and, if extreme, may affect one’s self-esteem.

Patient discussion about halitosis

Q. What causes bad breath? I have bad breath for a long time. What causes it?

A. Here are some causes of bad breath:
A Dry mouth- Saliva helps cleanse and moisten your mouth. A dry mouth enables dead cells to accumulate on your tongue, gums and cheeks. These cells then decompose and cause odor. Dry mouth naturally occurs during sleep. It's what causes "morning breath." Dry mouth is even more of a problem if you sleep with your mouth open. Some medications as well as smoking can lead to a chronic dry mouth, as can a problem with your salivary glands.
Some Diseases can also cause bad breath- Chronic lung infections and lung abscesses can produce very foul-smelling breath. Other illnesses, such as some cancers and certain metabolic disorders, can cause a distinctive breath odor. Kidney failure can cause a urine-like odor, and liver failure may cause an odor described as "fishy." People with uncontrolled diabetes often have a fruity breath odor. Chronic reflux of stomach acids from your stomach (gastroesophageal reflux disease, or GERD)
