Truthfully? OP may work for you, and it may not. You have to be patient. This is a food cure.
The reason you should continue, even though you may not experience gum regrowth, is all the posts from people who have avoided gum surgery. That in itself, more than visual changes, should keep you going.
I rub my gums with my fingers to stimulate them. I have added various essential oils as compliments to the swishing oil, like Oil of Oregano and Peppermint, and Tea Tree Oil.
I think we are all individual. I'm bummed that my gums have grown back somewhat, but not all the way. But they do look healthier, pinker, less anemic.
My two cents.
