had sore sensitive gums for 9 mos now that would bleed when flossing, couldn't heal them up with nutrition, supplements, mouthwashes. my integrative dentist recommended ozonated olive oil topically and after two treatments the next day I can floss with no problems. It tastes vile but worked immediately. Looks like a salve in a small container, tastes like gorilla glue.
The way I understand it, it chokes out the bacteria, virus and or fungus causing the gums to be irritated sore and bloody giving them the opportunity to heal. Of course diet plays a large role, we try to eat on the guidelines of the wapf as best we can.
