Does oil pulling really work for detoxification?

I was a skeptic who decided to see if it works. Now after 5 weeks of oil pulling I can say it works for gums, teeth, better sleep, removal of mucus from your lungs or troth (I am not sure where it is coming from) but, after oil pulling I spit lots of it (it looks disgusting). As for detox I am not sure yet. And I am not sure how will I see if it works or not. I do have occasional constipation, water retention, allergy and Arthritis in one joint. I will continue for another 2-3 months to see if any of it goes away
