Page 1 of 2You’ve tried mints, gum and mouthwash but nothing works. Bad breath is affecting your social life, causing you to shy away from your loved ones and preventing you from speaking up at work. You’ve already spent a small fortune to cover it up, but it never stays away for very long. What really causes bad breath and how can you get rid of it?
Is it Temporary or Chronic?
Temporary bad breath can occur after eating certain foods, such as onions and cabbage, which contain high levels of sulfur compounds. When these foods are digested, the sulfur compounds are absorbed by the bloodstream, carried to the lungs and released in the form of bad breath when you exhale or speak. Changing your diet to avoid foods like these can help prevent this type of bad breath.
Chronic halitosis, or long-term bad breath, is another story.
Bacteria flourish on your tongue, especially towards the back third. These bacteria break down the leftover food in your mouth, resulting in substances called volatile sulfur compounds (VSCs). These VSCs are the most common cause of bad breath. To treat this kind of bad breath you need to reduce the amount of bacteria in your mouth.
The bacteria responsible for bad breath thrive when your mouth is dry. Conventional mouthwash, which contains alcohol, dries out your mouth and may actually cause bad breath more than it helps. Instead of an alcohol-based mouthwash, look for alcohol-free varieties or products that contain "chlorine dioxide," which attacks the VSCs at the molecular level to treat bad breath at the source instead of just covering up the smell.
One of the easiest ways to do this is by maintaining good oral hygiene—regular flossing (daily) and brushing of the teeth and tongue (at least twice per day). The tongue is a hotbed of bacterial growth, harboring millions of organisms in a bunch of tiny nooks and crannies. The most efficient way of cleaning the tongue is with a tongue scraper, a special tool made of plastic or metal that is scraped along the surface to remove the film of bacteria. The scraper should be placed as far back on the tongue as you can to remove the most bacteria as possible.
While you can brush your tongue with a regular toothbrush, a study by The Cochrane Collaboration found that tongue scrapers are more efficient at removing bacteria, removing 44 percent of VSCs (compared to the 30 percent removed by simply brushing the tongue).
