t say it, but I have a technique to detect it which consists of inserting a finger as deep as I can in my throat, then leaving it for a few seconds to dry up. If the finger smells horrible (and it
does), I'm pretty sure my breath does too.
I have very good oral hygiene, use a powerful mouthwash, but I'm still quite sure my breath from deep inside will smell bad.
However, there is ONE thing that helps: taking metronidazole pills.
