A hint to help find the source of ur bb

[Bb5yrs]

I found this statement online:


Following an oral examination, the next step may be breath tests to determine if the odor emanates from the mouth and throat (oral origin) or lungs (bodily origin):
The person blows forcibly through the nostrils while the mouth is closed. If offensive odor is detectable, it has a systemic (general or bodily) cause.
The person closes the nostrils by pinching with their fingers and ceases breathing momentarily, with lips tightly closed. While the nose is still closed the person opens their lips and exhales gently. If malodor is noticeable, it is of local, oral origin.


So this mean if the bb is from mouth or throat u should only feel bb from mouth right? Agree or disagree?
