I've been pulling for the last 2 weeks, using Safflower Oil, though once it is used up, I plan to get sunflower. I do it once a day in the a.m. I try to do it for a total of 10-20 minutes. I use multiple spoonfuls, spitting it out when it gets foamy. I rinse with salt water. I continue to use regular toothpaste.
So far, the biggest improvement is my gums. They are less red and swollen, and becoming a healthy pink. I can't say yet that my teeth are significantly whiter. I get increased post nasal drip after swishing, and I currently have a sinus infection that I am unsure whether it has come about because of swishing or not.
