Sinus-related Bad Breath
Hi, I have has sinus-related bad breath for years. There seems to be no way to fix the sinus problem but i am more worried about the breath anyway. It seems clear from the research that it is from nasty bacteria in the mouth that feed off the mucous. I have tried everything but nothing is works. Hydrogen Peroxide seemed effective for a couple of days but now it appears the bacteria have somehow made a come back. Anyone have any ideas?
