Bad Breath Problem

How to understand that you have a bad breath problem?
1. 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 of a halitosis problem.
2. Put your hands in front of your mouth and nose, and exhale.
3. Lick the back of your wrist, let it dry for a minute or two and then smell it.
4. Ask a close friend if your breath is unpleasant.
Ask your dentist.
5. Use a halimeter (measures the levels of volatile sulfur compounds in the breath)
