I have bad breath all the time but mostly during and after I eat. It is a foul smell that people around me can smell. I can't eat in public because of this. Also I brush, floss, scrape my tongue, and rinse and still have the odor. I think it is coming from my throat or stomach. I have been to my Gastro doctor, my dentist , and my ent and no one can help me. Please can you help me.
