I've gotten real good results with OP = Oil Pulling = rinsing the teeth and gums with oil for a few minutes a day. My teeth and gums seem much healthier after a few weeks of doing it. I use the OP forum, but I'd like to see if people who haven't tried OP may like to try an experiment. Normally, just certain oils are recommended for OP, but my theory is that any oil would work. The oils normally used are more expensive or harder to find than store-bought oil. I'd like to hear from anyone who'd like to try the mouth rinse using normal cooking oil, or shortening, or margarine, or butter. I wouldn't swallow the first 3, but butter is nutritious, so I'd swallow that, rather than spit it out after a few minutes of swishing. If other oils work too, a lot more people would likely try it and could greatly improve their teeth and gum health. Any volunteers? I don't know if these other oils will work, but I think it's worth finding out.
