I know someone who used Pascalite Clay for her gum infection and that worked too, she mixed the clay to a very thick paste and put it right on the area. It extracts toxins and bacteria and poisons, etc.
Since Oil of Oregano worked quickly for me, I'm sticking with the OOO, if I ever get another infection, but I'm using a drop of OOO in my Sunflower Oil and, oil pull, that should keep any infections at bay. :)
