same here. Have been OP-ing for about two months, 10 minutes every morning, everything according to the simplest protocol, sunflower oil, no extra additives. Had all the clean-teeth-benefits and the nice feeling in mouth and i found it was also very relaxing to start the day with. I even felt that the relaxed feeling stayed on during the day.
But then in the second month I could not help noticing that my teeth were getting more sensitive with every day. Cold or warm drinks were starting to be really painfull, biting on something hard was causing me pain.
When I stopped the OP-ing the pain was gone in two days and has not returned since.
Regretfully I decided not too do any more oilpulling and i also would not recommend it to anyone who has no particulair issues with dental health.
I did it out of curiosity and out of cleansing motives, I enjoy rather perfect health, so no miracles cures needed for me. Shame about the beautifull white teeth, but if I would venture to interpret, then I take the oil was taking some protective layer from my teeth.
But that is just guessing.
I have been OP'ing for many months now and have noticed this when I have stopped and started up again. I have wondered if it is due to my mercury fillings. What is the most uncomfortable for me is brushing with baking soda, although I have not had the other symptoms you describe. It has gone away, though (obviously I am still OP'ing so it is not as bad as yours, but I thought I would share my experience!).
i have been oilpulling for over a year now. I have gone thru some sensitive periods, one was just before my abcess got better and then I had no pain at all after going thru alot of pain and sensitivity for a few days. I think it is the gums and teeth detoxing the extra mercury that got into them from my old mercury fillings that I had removed and replaced. So I don't worry too much about it as I view it as the bodys way of pulling these toxins out of us and so I expect we will have some discomfort on the way.
I have had so much positive results with oilpulling. It took about 4 months to rid me of allergies that I had since I was 22. I don't have the build up of plaque on the bottoms of my teeth anymore. I had some vertical lines on my cheeks that are not there anymore. So I feel it is anti-wrinkle. I did have a blister come up on my bottom lower gums, but I continued to oilpull and it also healed itself. I view these as toxins being pulled out from the gums. My teeth still get sensitive now and then but I view it as a good thing since I read that the body detoxes in waves, not all at once. It knows when it is well enough to dump toxins. Sometimes we have to go thru the clouds to see the sun. This is all IMHO.
