The majority of bad breath problems begin in the mouth.
Odors coming from the stomach are almost never the cause of chronic bad breath.
It is estimated that nearly 60 million people suffer from chronic halitosis in the United States. Bad Breath or Halitosis is caused by an imbalance of the two types of bacteria that live in our mouth. We are born with two types of bacteria that live within our body. The anaerobic bacteria are an opportunistic type and therefore should we upset the natural balance of our mouths, they tend to grow more quickly, eventually dominating the oral environment. These anaerobic bacteria when they flourish produce copious amounts of sulphur compounds as a waste material.
