How to understand if you have halitosis problem
If you notice that when you speak people around you try to keep you at a distance or take a step back, you have a first hint.
Put your hands in front of your mouth and nose, and exhale.
Lick the back of your wrist, let it dry for a minute or two and then smell it.
Ask a close friend if your breath is unpleasant.
Ask your dentist.
Use a halimeter (measures the levels of volatile sulfur compounds in the breath)

Certain foods, health conditions and habits are among the causes of halitosis. Most people can find a cure for halitosis with proper dental hygiene. If bad breath persists despite good oral hygiene, you have a chronic halitosis problem and you should visit your dentist or doctor to rule out a more serious condition that may be causing your bad breath.
