[|Human|] Hi. I ve been suffering from bad breath for how many years now. It s so frustrating because I brush three times a day and even floss. I also have regular visits to the dentist. When talked to him about my problem, he said that my oral hygiene is fine. When I brush my teeth, it stays fresh for a about half an hour and then it starts to stink again. The stink isn t just from when I talk but when I breathe as well. I was hoping you could help me figure out what the problem is.
[|AI|]  Thanks for your query, I have gone through your query. The bad breath or halitosis can be because of the gum infection or food lodgment, since you are telling your oral hygiene is good, the other possible causes of halitosis can be because of respiratory tract infection or gastrointestinal disorders. Nothing to be panic, consult a pulmonologist and gastroenterologist and get it evaluated. Meanwhile, you can use mouth wash containing chlorhexidine. I hope my answer will help you, take care.
