Question: My daughter has developed dreadful bad breath. She cleans her teeth well, so we’re at a loss as to what's causing it.
Bad breath is often a gut-related condition. When the billions of beneficial bacteria in your intestinal tract get out of balance with the bad bacteria, your daughter may have digestive problems, even if she doesn't experience the pain of indigestion.
If food is not digested properly, it can cause acid reflux, yeast overgrowth, or fermentation in the stomach; these all trigger bad-smelling by-products which rise up as bad breath.
