I can't get rid of this white tongue bacteria!!

Around the back of the tongue is where it gets really white, that pic probably doesn't show it enough. This has caused me bad breath for years and I don't think it has ever gone away. I brush my tongue, floss, use a tongue scraper, and nothing helps. I chew gum and the constant flow of saliva keeps it from reeking I guess.

What exactally is this white bacteria that won't go away? Maybe a super strong mouthwash will eliminate the problem? Please help! Thanks!

I am really not sure--I do not know if you have your tonsils, I have heard that an odor can eminate from the tonsil area.It might be advisable to see an oral pathologist for a consultation. These doctors can usually be located at teaching hospitals or dental schools.
