What are causes of bad breath?

Bacteria on tongue. Bad breath is most often produced by bacteria in at the back of the tongue. The stomach rarely results in bad breath except when there are specific digestion issues. Cleaning teeth, including inbetween, and the back of the tongue with a tongue cleaner often helps reduce bad breath.
Many causes. Many things can cause bad breath, including cavities in your teeth, periodontal problems, acid reflux, sinus infections, and diet. Since you cannot be evaluated for all of these conditions over the internet, seek the care of a local dentist and physician who can examine you and treat you.
Good Hygiene 1st. If you already have a good oral hygiene routine, it could be dehydration make sure to drink plenty of water. Eating desserts at night before bed and not brushing your teeth can show up as bad breath in the morning. A whole list of medical conditions also cause bad breath, diabetes is the most common.
Multiple factors. Gingivitis and periodontal disease are the main culprits. Also food left between the teeth from not brushing and flossing. And plaque left on the teeth can cause bad breath. I think one thing people fail to do is brush their tongue. The tongue is like a thick carpet collecting bacteria and odors. See your dentist to check for periodontal disease, brush, floss, and brush the tongue.
Multiple Answers. First find the cause and deal with that directly. Typically, bad breath stems from bacteria between teeth, on the tongue and around the gums. Fortunately, this problem is often easy to fix: good oral hygiene (brushing 2x day, flossing & brushing your tongue), regular visits to your dentist (to prevent gum disease), and ruling out any underlying conditions or other factors.
