I don't doubt that it can. I have been "swishing" for about 2 1/2 months and have also experienced weird symptoms- low grade fevers, and joint and muscle pain that I used to get when I was pregnant. I haven't had the pain since I was pregnant until now- my baby is 13 years old. I feel like the pulling reverses your symptoms or "dis-eases" out of your body kind of like fasting does. These aches pains, etc. are cleansing symptoms in my opinion. Those who don't feel anything may be so healthy that there is nothing to get out of you. My intuition tells me that there is definitely something to this goofy ritual. For the molar pain, brushing with hydrogen peroxide may help you. Either regular or food grade diluted with half water/half 35% peroxide.
