My experience some what close to yours. Of course my teeth problems was chronic, and when I started oil pulling, one of my tooth became and wobbly and fell after few days. I had route canal and cap and that one also fell when I started oil pulling. I used only cold press organic sesame and sometimes coconut oil. May be my bone loss was severe. But most importantly, I read in one ancient ayurvedic book, that our gum health is the mirror of our intestinal health. So from my experience, I want to advise that take care of what you eat and how your bowel moments are. Because when I constipated, my gums were swelling that day.
