Cure for bad breath?

Depends on cause: There are many causes of bad breath, both of dental and medical origin. There is no real "cure". You can prevent or treat bad breath based upon what is causing it. For example-(a shower will make you clean, but that will not prevent you from getting dirty). See the following website for some guidance or speak to your dentist (or physician).

Where is it?: You must first find out where it is coming from? It could be your mouth (teeth or tongue), throat (tonsils or adenoids) or even stomach (hiatal hernia) before you can come up with a cure.

Self diagnose it!: Other than common food odors that come from ingesting garlic etc. Entering the blood and exit the lungs (or rare stomach malignancies) most bad breath comes from the surface of the tongue, ;/or from between the teeth. Floss twice daily. (skipping one day is like not flossing at all). And brush your tongue, with a touch of toothpaste, the farther back the better. Odds on, bad breath reduced.

Bad breath: Other than some relatively uncommon causes (neoplasms, GERD, diabetes, tonsil stones) most bad breath is caused by sulfur producing bacteria. Most often from 1) bacteria collecting on surface of tongue, use tongue scraper or brush tongue daily) or 2) most commonly, gum disease from food/bacteria getting trapped between teeth and under the gums. Floss daily (EVERY day). See your Dentist.

Determine the cause: Then start care. Your halitosis may be coming from periodontal problems, cavities, infections, or acid reflux. Once the cause is determined then treatment can be instituted.
