Bad Breath Cures serious answers only please?

bad breath
swordtail1971 asked:

I constantly have bad breath, I brush 2 times a day, floss, use mouth wash, I use a tongue scrapper and everything, i’ve even taken pills that claim bad breath is caused by something in your stomach. Nothing seams to be helping. i’ll chew on gum or have a mint when it gets really bad but it does not last for to long. I really need some help please.
