The floss test:
Work a strand of flavourless dental floss between your back molars and give it a whiff. If it smells like rotten eggs, then most certainly you have bad breath. The smell actually is from plaque, which is a thin film of microorganisms, which everybody has to some extent. But the stronger your plaque smells, the more likely it is your breath stinks too.
Watch your tongue:
Stick out your tongue. Do you clean it on a regular basis with a tongue scraper? If not, in all probability it has a thick white coating comprising debris, bacteria and food particles that favours an ideal environment for volatile sulphur compounds. Now rub the back of your tongue with a clean piece of cloth. If it smells pretty nasty (like sulphur), then you have this dreaded problem of bad breath.
Now this isn’t quite a reliable method, but still the easiest way out. Lick the inside of your wrist, allow it to dry and then smell it. If it stinks, you know how your breath is or rather shouldn’t be!
If these methods don’t seem too reliable and you want to know for certain; ask your dentist – he/she may be able to help you with your problem. By the way there are several laboratorial methods for diagnosis of bad breath:
Halimeter is a specialized type of sulfide monitor, which will measure the concentration of sulphur compounds in your mouth that produces halitosis or bad breath and determine if your breath stinks.
This technology is specifically designed to digitally measure molecular levels of the three major VSCs in a sample of mouth air (hydrogen sulfide, methyl mercaptan, and dimethyl sulfide). But gas chromatographs are relatively expensive and require personnel with special training to operate them.
The BANA test:
Some of the bacteria that cause periodontal disease (gum disease) produce waste products that are quite odoriferous and as a result contribute in causing bad breath. The presence of some of these types of bacteria can be tested for by way of performing a BANA.
Organoleptic measurement test:
Here trained experts use their own sense of smell (the nose) to evaluate the breath.
