I brush, floss, tongue-scrape, and use mouthwash regularly, especially before bed. Yet I cannot seem to eliminate the malodorous fumes that emanate from my mouth each morning upon awakening. I recently met someone with whom I think I might be developing a close relationship, we sleep together, and so this problem is now of prime importance. Thank you.

Everyone has morning breath... and that's a result of the hours you are asleep the odor causing issues aren't in hibernation.

Some peoples are worse than others... but remember NOBODY has minty fresh breath after sleeping 6+ hours since they brushed their teeth.
