In brief: Poor oral hygiene!
While acid reflux can be an issue, it is no longer considered a primary cause of bad breath.
The major causes of non-food related breath odors (garlic etc.) are gum disease and rotting food particles on the tongue. Floss daily ; use a toothbrush w-toothpaste to brush as far back on your tongue as possible. (colgate total with antibacterial triclosan works great!) voila, no more bad breath!

I have been treating patients with Halitosis for almost 27 years. A lot has changed in this field ! One thing most doctors misunderstand is the term " good oral hygiene " and how good oral hygiene eliminates bad breath! The effect of " good oral hygiene " is 100% equivalent to " good toilet paper use" on this smelly problem.... You CANNOT kill odor producing bacteria by toothbrush / floss!!

You can only move bacteria from place to place with toothbrush...and if you never STERILIZE your tooth brush after every use, then you just reintroduce bacteria back to your mouth next time you brush

In brief: Several things
There are many causes for bad breath.
Among the more common are gingivitis (inflammed or infected gums), possibly from poor brushing and flossing, and little stones that are formed in the holes in your tonsils, called tonsilloliths. There are more rare causes too. If good brushing and flossing doesn't help, you might see your dentist, primary doctor or nurse practitioner for help.

In brief: Anaerobic bacteria
Bad breath is caused by billions of bacteria in your mouth, the same bacteria also may cause gum desease.
The reason it smells is bacause those bacteria produce gases and other waste in your mouth, and when you exhale, people around you may smell this very characteristic smell.
