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.

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.

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.

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.

Bacteria: Primarily bacteria. There are foods that can temporarily give you "bad breath". The oral cavity "mouth" is aerobic. When people have periodontal disease, there is a proliferation of anaerobic bacteria that should not be there. Some are really nasty and as they destroy the tissue and bone the smell is a necrotic dead smell. Other causes are the tongue and post nasal drip. See your dentist.

Non-dental causes.: Aside from the usual dental culprits such as poor oral hygiene, infection, & periodontal disease...you can also get bad breath from acid reflux or a post-nasal drip. If your friend has good oral hygiene & no dental issues, then consider visiting your primary care physician or internist & getting checked out for any of the above health issues. Also, don' forget to cut back on the onions & garlic.

Bad breath: In the majority of cases, the cause of bad breath, or halitosis, is the product of bacteria in the mouth and gum disease. The proper diagnosis is the key to a successful treatment. See your dentist for Halimeter test, diagnosis and bad breath treatment that depends on its cause. Good luck.
