Bad breath is caused by bacteria in your mouth, esophagus or stomach. If you do not brush your teeth and floss regularly, bacteria build up between the teeth. This bacteria causes the smell, and brushing and mouthwash will just cover it up. See your dentist for a professional cleaning to remove the bacteria colonies. Bad breath can also come from your stomach. Your doctor can give you more advice for eliminating this type of bad breath.
