Most mouth odor originates from the tongue. Try brushing twice a day, flossing once, and each time you brush your teeth, also brush your tongue. The tongue should be brushed using only water, not toothpaste. You can get tongue scrapers to help get that white coating off if you want, but your toothbrush can probably do the job just fine. The white coating is a good indicator that the problem is coming from your tongue. Rinse well with water after cleaning your tongue. If the problem persists, you might want to consult with a dentist.

Hope this helps,
