Poor oral hygiene allows food particles to collect on the surface of the tongue, between the teeth or along the gum tissue that surrounds the teeth.
Unfortunately, an occasional battle with bad breath is an experience that many share, and researchers estimate that more than 80 million Americans suffer from chronic halitosis. Nico Geurs, DDS, the Dr. Tommy Weatherford/Dr. Kent Palcanis Endowed Professor in the University of Alabama at Birmingham School of Dentistry, says bad breath can result from the development of a biofilm of bacteria that emits a bad odor.
‘Morning breath is a common form of bad breath, and according to the ADA, people with dry mouth are at an increased risk.’
"Bacteria can organize on the tongue, teeth and mucosal surfaces," Geurs said. "An additional source can come from the throat, esophagus and stomach, and expired air from the lungs." Poor oral hygiene allows food particles to collect on the surface of the tongue, between the teeth or along the gum tissue that surrounds the teeth. Naturally occurring bacteria in the mouth then break down those food particles, releasing chemicals that have a strong odor.
"Brushing twice a day can prevent biofilm formation," Geurs said. "If this is the source of bad breath and no gum disease is present, twice-a-day brushing can make a difference. Brushing your tongue and flossing are important also."
Geurs recommends scheduling regular dental visits to maintain a healthy mouth, adding that cavities, gum disease pockets and coated tongues can harbor bacteria that release sulfur compounds that can smell like rotten eggs, smelly feet or fecal matter.
Infections in the mouth, like tooth decay, gum disease or mouth sores related to other conditions, also might contribute to bad breath. Surgical wounds from extracted teeth also can be a source of halitosis.

Morning breath is a common form of bad breath, and according to the ADA, people with dry mouth are at an increased risk. "During the night while you sleep, the salivary flow decreases and changes the bacteria in your mouth," he said.

Dentists can help identify the cause of bad breath. The diagnosis could be simple based on patient history and complaint, and dentists can even use a device that measures volatile components in the breath. If the bad breath is due to an oral condition, dentists can develop a treatment plan to help eliminate it.
