I had allergies that improved with oilpulling. It took a couple of months for me. I had noticed right away how it cleared my sinuses. But it also took a couple of months for my teeth to get whiter. I don't feel anymore plaque on the bottom of my teeth where it used to settle either. I did have some detox reactions but I felt so much better afterwards. I think oilpulling is more suttle-the longer you do it-the more changes you will notice.
