  1. 1We’ve all done a hand check, right? But other than a false sense of security -- or maybe a hand that smells -- what does it prove? Not much. But what we do know is you are what you eat. When you eat, food starts to be digested in your mouth. Bacteria break down food particles and releases sulfur compounds that are involved in bad breath.
  2. 2Another cause is poor oral health. Bacteria from tooth decay or gum problems will linger in your mouth like a vacationing guest at your house, so ask yourself: Are you really brushing and flossing as you should? Are you using an antibacterial mouthwash? A more severe problem, like gingivitis or periodontal disease, will require professional intervention. So visit your dentist regularly as part of your battle against halitosis.
  3. 3Speaking of bacteria, your tongue can be a magnet for unpleasant germs and smells, so don’t forget it when you’re brushing. If your tongue feels like it needs to be shaved with a razor, brushing may not be enough. If that’s the case, use a tongue-cleaning device to scrape it clean. You might even get one free when you see your dentist.
  4. 4It may seem obvious, but eau du tobacco … no. If you want fresh breath, don’t smoke.
  5. 5How wet is your whistle? Saliva is the body’s natural way of keeping your mouth cleansed, and the salivary gland doesn’t work as well if your well is dry.
  6. 6Finally, persistent bad breath could be the sign of a major medical problem, like acid reflux, sinus infections, diabetes, or kidney problems. So make sure you get regular medical checkups and follow any special instructions your doctor may give you.
