I am sorry that you have had to suffer so long with this problem. I’ve found that my candida-related breath issues can be kept under control by doing two things:
1.) I put a good amount of sea-salt on my tongue, leaving it there for about five minutes before spitting it out.
2.) After rinsing out the salt, I open up a probiotic capsule and pour the contents onto my tongue. I then use my toothbrush to spread the probiotic all over the tongue surface. I keep the probiotic in my mouth anywhere from 5-20 minutes before swallowing. I usually don’t use a whole capsule; the amount you use will vary with the strength of the probiotic.
These things have helped me significantly over the last few weeks. I am hoping that it is a long term solution and that they remain effective in the future. I usually repeat these steps 2-3 times throughout the day.
Hope this helps. Whether or not you have candida, I would think these things could prove effective against the bacteria causing your bad breath.
(Also, don’t use table salt. I’ve heard that it can be harmful.)
