Bad Breath Halitosis Forum

we all know if we test our bb by use finger swab on tongue or throat and smell finger, we can smell odor although we don't have bb because low vollate sulfur compounds on tongue or throat. on the other side, we use finger to swab on tongue or throat then smell it and we don't smell any bad smell from finger but people
say you still have bad breath. why???

My gums used to smell before I had my wisdom teeth out. I don't have tonsils either. My tongue looks dirty but does not smell either. It could be our stomachs or something deeper in our throats. If you floss what does it smell like?

my bb caused by PND. therefore, i don't have issue about my gum and my teeth ( dentist checked).

in my opinion, we can have bb by tongue although when we swab it and it does not smell. because anaerobic bacteria make high VSCs ( which make people smell our bb) while low VSCs are made too little

i also checked all areas of my throat ( it makes me nausea) but don't have bad smell on finger.
