Larimar, that's great! I'm so glad it's working for you.
I can't imagine not doing it now...it doesn't feel right if I don't oil pull for a day or so. I don't know whether it has been detoxing - no symptoms here really - but my mouth, gums and teeth feel great, and I had a good dental checkup too. My teeth are a bit whiter. Not blindingly white like bleached, but definitely lighter with less tartar.
Hillaire, if you brush after oil pulling it should leave your teeth feeling very clean, shiny, smooth. It takes some getting used to. Your tongue muscle will get sore if you pull too vigorously. Maybe slow down a little and go easy? Hmm...I can't explain the chapping. What kind of oil are you using? I use organic cold pressed sesame oil and it works well for me, no weird reactions.
Ellemartini, I sometimes brush wtih hydroden peroxide diluted with water, too. Sometimes I brush with Listerine.
After oil pulling I rinse with warm salt water.
