Occasionally or Regularly?
Bad breath (halitosis) is a common problem, which often comes from the activity of bacteria in the mouth. Although there is no way of knowing for sure, most adults probably suffer from bad breath occasionally, with perhaps a quarter suffering from it on a regular basis.
There are two types of bad breath. Transitory, or occasional, bad breath is caused by foods like garlic and onions and generally only lasts from 24 to 72 hours. It might be referred to as "morning breath," which goes away after you brush your teeth.
Chronic, or regular, bad breath does not improve over time. In some instances, chronic bad breath is actually caused by underlying medical conditions like diabetes, sinusitis or emphysema. And in those rare situations, treating the disease could possibly eliminate the cause of the bad breath.
The odor of chronic bad breath results when bacteria in the mouth and on the tongue cause the formation of volatile sulfur compounds (VSC's) in the form of hydrogen sulfides. The back of the tongue is the prime breeding spot for anaerobic bacteria that creates odor-causing Volatile Sulfur Compounds. This may be an ongoing problem requiring professional breath management.
Talk to your dentist about bad breath. He or she may have a treatment that fights both the cause and effect of bad breath.
