Oil pulling?

I started oil pulling last night..not sure if any of you know what oil pulling is, but you use coconut oil or sunflower seed oil and swish it in your mouth for twenty minutes. The benefits for oil pulling is to help whiten your teeth and detox them from cavities (other people believe it does a bunch of other crazy things, but these are the only ones I care about haha). It is recommend to do it when you are showering because you do not really think about it since 20 minutes and that is a long time for swishing something in your mouth! I know this sounds like some crazy thing to do, but I have bad teeth (which is genetic so thanks mom and dad) and I try to take the best care of them. Unfortunately it does not matter how well I brush my teeth or floss religiously, my teeth still manage to get a cavity...so hopefully this oil pulling does miracles for my teeth!
