<s>[INST] Dr. can you really change my life? I am seriously in problem with chronic bad mouth odor which is too strong. I dont smoke. I eat spicy foods only some times. I went to doctor and he cleans my tooth only with some fluid but still no change. It becoming worse from time to time. I need your help now. [/INST] Thanks for your query, I have gone through your query. The bad breath 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. Consult an oral physician and get yourself examined to rule out these conditions. 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. Since you are telling you have got your teeth cleaned and the problem is still present, so you can consult a pulmonologist and gastroenterologist and take an opinion. I hope my answer will help you, take care. </s>
