Hi, may I answer your health queries right now ?  Please type your query here...Hello, I am very embarrassed and feel sick even talking about the following
Thanks for your query, I have gone through your query. Nothing get frustrated about halitosis. The most common causes for bad breath or halitosis could be because of the deposits over the teeth causing gum infection. Or it can be because of the pus discharge secondary to gum or tooth infection or any respiratory tract infection like sinusitis or gastrointestinal disorders. Since you are telling it is not gum infection, consult a pulmonologist and gastroenterologist to rule out respiratory tract and gastrointestinal disorders if it is gum infection get the teeth cleaned once and maintain oral hygiene after that. You can use mouth wash. If it is tooth infection get the tooth restored. I hope my answer will help you, take care.
