I'd encourage you to read the page linked, I've only quoted the core of it.We found that gastrointestinal pathology was very common in patients with halitosis and was present in 54 of the 94 patients (57.4%). Pathology was noted regardless of dental or otolaryngological findings. Most pathologies, both macroscopic and microscopic, were noted in the stomach (60% non-H pylori related), followed by the duodenum and the esophagus.
As for me I've aleady pretty much dropped toothpaste, flossing and mouthwash (the latter unless I know I'll be interacting socially). Not because of this study of course but just personal experience, it's obvious that in my case these things don't do anything, mouthwash gives a little relief as it covers up for a while.
Anyways this is about the common myth 90% of bad breath has its cause in the mouth we keep hearing in every commercial and from every dentist, and I'm posting this for the thousand of times we read about scraping our tongues in here.
