May be your stomach: Halitosis may have many causes. It sounds like you are taking good care of your teeth. If you are continuously getting a white coating on your tongue it may not be related to your teeth. Various medications can cause an overgrowth of the cells on your tongue and they can harbor bacteria which may cause the odor. Sometimes it can be related to your digestive system, check with your md.

Stomach issues?: If you have completely ruled out all causes orally then the source of your halitosis could be gastric. Parsley oil supplements may help in this case. Try getting a tongue scraper as they clean better than a brush and try to not to eat foods that are high in sulfur compounds or protein. In my experience people with this problem usually have undiagnosed periodontal disease.
