You could just zap. It kills any hatched out parasite anywhere but the deep bowels (but not eggs). My parasites don't come back, or scatter. It has nothing to do with any oral condition for me.But if you think putting poisons into your body time and time again is better than a bit of harmless (except to parasites of course) electrical current, well knock your self out, eh? I never found the parasite zapper to work that well against infections though, although Dr. Clark believed they did. And almost all parasites carry in infections--which type depends on the parasite.
