I am a 30-year-old girl suffering from a very smelly breath. People usually avoid talking with me. I have already read the answers for the problems in the same category but my case is a little different. I go to dentist every six month. I have checked my stomach and doctors say that I do not have helico-bactria in my stomach which is one of the causes of this problem. I have a slight sinusitis but doctors say it can't be the cause of this extremely bad smell. I also have had a very slight pain in my throat for 3 or 4 years. I usually breathe with both mouth and noise but during sleeping I just breathe with open mouth.
When I was a child I had a tonsil surgery and they took out my tonsils. Can it be the cause of this problem?
