Answer 3

Halitosis is the scientific name for bad breath, and it can be caused by several things. Temporary halitosis is something you're already familiar with. That's what happens when you eat something that smells, when you first wake up in the morning, when you don't brush your teeth and tongue, smoking, that sort of thing.

Chronic halitosis is a bit different. It can be an indicator of a few diseases. It can be a simple over-population of certain bacteria in your mouth. Or it can be an indicator for something more serious, such as in chronic liver failure; it can make your breath smell like a decomposing body.

Answer 4

These are of many kinds:
Pyorrhea caused by Bacteria and aggravated by Entamoeba gingivitis results into bed smell.
Improper brushing-----food particles in mouth are attacked by microorganisms and there may also be fermentation reactions.
Some foods like garlic, onion, asfatodia contain alkaloids and are recognized as bad by some people.
It can be well stated by the example of alcohol.
Alcohol after entering in blood is excreted out from lungs in form of vapors. It is one of the way of our body to remove alcohol from blood. As smell of alcohol comes from lungs therefore freshener doesn't work. And it is true for some other food components also eg. cigarette, some drugs, and foods etc.
