Well Trapper has been experimenting with the remineralization thing, so he can speak about that.
As far as gum inflammation, you are definitely in the right place at the right time. I'd say get the best oil you can, and do this twice a day (morning and just before dinner). Try one oil in the morning, and another at night. I'd make one of those oils Hemp, because as far as I can tell, that's one powerful pulling action.
I'd also swish with a few drops of Oil of Oregano (make sure it is not diluted with something else like Olive Oil). I'm going to start putting Black Cumin Seed Oil in my oil pulling, because they say that it cures everything but death.
I'm sure others will chime in. This is just my 2 cents.
