I have bad breath. I brushed Daily and antiseptic mouth wash Daily. But still have Bad breath. I don’t have or a single cavity not ever. Could it be my stomach?

Please Answer both.
1.Is there such thing as chronic halitosis? (chronic or ongoing bad breath) Is it a disease or condition, or a real thing?

2. Can anybody tell me some tricks that work? I chew gum all the time, but the the breath comes back. etc.

My mouth gets incredibly dry especially when I take antihistamine. I take alot of allergy medicine. It dries me up in my nose and mouth ridiculously. Then my breath has that old person, moth ball smell and regular mints and gum don’t really help take the icky taste out of my mouth. Drinking water helps a little but not as much as I would like. Is there something I can take for this odor? it’s driving me crazy that whenever i’m sick or suffering from allergies i have this problem!!!! help!!!! I asked the dentist when I was getting my wisdom tooth pulled out, but because he couldn’t smell anything at the time, he just said he didn’t know and wouldn’t help.

I brush my teeth everyday twice a day and I brush my tongue too. I floss regularly. I use mouthwash. I use mints and gum. My bad breath doesn’t go away!!! Even when I put like 3 mints in my mouth at once, the bad breath only goes away for like 5 minutes? What do I do?
