[|Human|] Hello,Just curious, I have an acidic, slightly onion-like odor to my breath when I wake in the morning for the past week or so.  I quit coffee and switched to green tea recently.  Ive also switched to an exclusively whole grain diet, no dairy and high protein.  Could those changes be factors?
[|AI|]  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. Particularly as soon as you get up, because during nighttime the salivary flow will be less and the cleansing activity will be negligible. The other cause 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. If it is respiratory tract infection consult a pulmonologist and gastroenterologist if it is a gastrointestinal disorder. I hope my answer will help you, take care.
