I brush three or two times a day.
I floss once or twice a day.
I use mouthwash.
I clean my tongue.
I use breath mints and gum.
I have no cavities or gingivitis or any other gum disease.
What can be wrong?
And I don’t eat such foods as garlic, fish, or other obvious things that make breath stink.

the odour might be emanating from the gut…it can’t be from your mouth..i dont do half the things on your checklist and i dont have bad breath..
Maybe it has something to do with your stomach? That can be a cause of bad breath. Also for a cleaner mouth try brushing your gums and cheeks too.
