Bad breath or Halitosis is a term used to describe noticeably unpleasant odors exhaled in breathing—whether the smell is from an oral source due to bacteria or otherwise.
Bad breath is usually caused by poor oral hygiene habits, infections that occur in the mouth, unhealthy habits, such as smoking and alcohol intake, and foods that you eat.
Other culprits include dry mouth, respiratory tract infections, systemic diseases such as diabetes, kidney, liver and lung disease and gastrointestinal issues, which may include acid reflux and other stomach digestion problems.
Treatment for bad breath (halitosis) will depend on its cause.
