<s>[INST] 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: I have suffered from bad breath since my teens. I am now 40! I have thick saliva like substance at the back of my throat and on the roof of my mouth. I was a severe asthmatic as a child but when I came to Australia it disappeared..I was 5. I do smoke but dont drink. I am very social but shy away from sitting next to people. I have mastered chewing gum without anyone realising that I have gum in my mouth. I have been to all the dentists, spent a fortune at the periodontist so my problem is not with my teeth or lack of oral hygiene. My mouth is dry even though I feel like I do produce sufficient saliva. I am always bloated and recently cant stop burping air (not very lady like). Air gets stuck in my chest and I feel uncomfortable as I try to hold it in if I am in public. Please, please help me. I at times feel like giving up on life as all I want is to be with people without worrying about them knowing or in my mind finding out that I have bad breath (they probably already know). [/INST] 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. </s>
