Do you practice oil pulling and what were your results?

I don’t know how new this procedure is for bodily and oral health but people are starting to talk about oil pulling . This is when you take an edible oil, such as coconut oil, and squish a teaspoon through your mouth for fifteen minutes then spit it out. It is supposed to whiten your teeth and do other great things for the body. What is your opinion of it? http://wellnessmama.com/7866/oil-pulling-for-oral-health/
