All I can say is wow. I am a loooong time lurker first time poster and this morning I did the oil pulling with sunflower oil for 15 minutes, I planned to go longer butgot a tickle in my throat. When I checked my teeth afterwards I couldn't believe it, the black areas inside the creases at the top of my molars had reduced by about half. This has been a concern for as long as I can remember and I had planned to get my teeth professionally cleaned as soon as I could afford it but with this sort of response from a one time oil pull, I am definitely sold on the practice. Now to get hubby to give it a try.
