What causes bad breath that does not go away?

Most bad breath comes from bacteria in the mouth, especially on the tongue and between teeth. Gum disease, dry mouth, smoking, and some foods add to it. Ongoing bad breath can also be linked to sinus, stomach, or other health problems. Regular brushing, flossing, and a dental checkup are the first steps before trying any product.
