Had this type of a reaction when I accidently swallowed some of the oil (yuk!!) - and oviously took back some of the toxins that were being expelled... or that´s what I put it down to. Was doing the oil pulling with sunflower oil. Not sure if switching oils, would have this effect. Just my 2 cents!!

Coconut oil is actually a strong detoxifier in addition to being anti-bacterial and anti-fungal. And the symptoms you mention are classic healing reactions (not to say it couldn't be something else).

Coconut oil is a wonderful oil to pull with. Detoxes, strong tooth/gum rooting action, whitens teeth and on and on. But personally I can't do coconut oil more than a few times a week - I need to revert back to something gentler like flax seed oil.

If I were pulling with coconut oil twice a day, I would expect these symptoms for myself - at least for awhile. Not only do I think twice a day is too often to pull coconut oil right off the bat, my personal experience is that I don't get any additional benefit pulling more than once a day with ANY oil. At that point I notice more harmless but annoying side effects than anything - but this is all just IMHO.
