I have severe bad breath. My dentist says my teeth and mouth are very healthy. The gastroenterologist put a scope through my mouth and said my stomach looks fine. Where do I go next? It is very embarrassing and depressing. I have a job where I have to communicate directly with people and a lot of avoid talking to me. Friday I began taking activated charcoal because I read that may help. I don't know what to do next. This is ruining my life.

Try using bicarb soda to brush your teeth, and make sure you thoroughly brush your tongue and gums.
I don't know how I would cope if I had constant bad breath, I hope you find a solution !
