Bad breath is a simple metabolic equation. Almost all cases of bad breath is caused by Volatile Sulfur Compounds (or VSCs) which are produced by a group of ANAEROBIC Bacteria living a in our mouth and throat, as well as in our digestion tract. These bacteria are actually present to assist human digestion by breaking down proteins found in specific foods, mucus or phlegm, blood, and in diseased or “broken-down” oral tissues. Once the coating is staying longer than the bacteria are able to break down the proteins contained in the coatings, under certain conditions, these bacteria starts to break down proteins at an abnormally high rate, which eventually releases the odorous and “lousy-tasting” sulfur compounds - which in fact is - the actual Bad Breath.
Poor oral hygiene is the most common cause of bad breath. When you do not brush and floss your teeth on a daily basis, any food trapped between your teeth or in your gums will be broken down by bacteria and eventually causes the bad smell. However, there are also a number of other factors that may cause the condition:
