Oral hygiene: It seems that you are practicing excellent oral hygiene which is a common cause of "bad breath" some bacteria can hide on the back of your tongue and may be removed with a "tongue scraper" which can be purchased at a local drug store. How much alcohol do you drink? Rarely, alchoholism can cause liver problems that result in bad breath. Consider seeing a doctor about this.

Bad breath: Brush teeth w soft t'brush for 2 full minutes BY THE CLOCK at least 2x/day. Floss DAILY to remove debris that t'brush can't reach. Try a tongue scraper--ask your Dentist for instructions. Have Tonsils/adenoids, sinuses checked by General Physician or ENT. Have GI function checked by GP or Gastroenterologist. Meds/supplements/vitamins can cause odor. Avoid alcohol. Do 't smoke anything.
