[|Human|] Hi! Im having problems with my breath. Ive tried licking my wrist & scraping the back of my tongue but I dont feel any particularly bad smell, it smells a bit sour, but nothing extreme. However whenever Im in a room talking to people they discretely hold their noses. People smell my breath from 6 feet away. Ive visited the dentist twice (my teeth are in perfect health, never had a cavity) and been to 3 ENTs, but they cant find anything wrong so Im stumped.
[|AI|]  Hello! Welcome to Chat Doctor. Gum infections can cause bad breath. As you saw your dentist and ruled out a dental cause, I suggest you to see your physician. Check if you have HERD.smoking and other tobacco habits also cause this. You did not mention anything about your general health. Diabetics, liver and kidney disease, tonsillitis and other respiratory infections potentially cause halitosis. Check if you have a low salivary flow. If any of the above includes your general health, this has to be corrected immediately. Use saliva substitutes if you suffer low saliva flow. Keep away garlic, onion,tobacco products. Brush your teeth and tongue twice daily. Maintain a good oral hygiene. Regards.
