After a month of oil pulling, I can't say that I've noticed an objective difference—my teeth aren't whiter, my mouth doesn't feel cleaner or different. But I do feel as though I am doing something good for myself and my mouth does feel cleaner just after doing it.
Oil pulling is an ayurvedic method of oral hygiene whereby one continuously swishes coconut or sesame oil for 20 minutes after brushing one's teeth, then spits it out. It is best if you brush your teeth or scrape your tongue afterwards, too, ridding your mouth of the bacteria-laden oil. The oil pulls out the bacteria that form the biofilm called plaque, which causes gingivitis.
Oil pulling is receiving a lot of attention in the past few years. Bloggers attribute all sorts of benefits to the practice including curing ulcers, solving menopause, "detoxifying the body", and medical miracles. That's the internet. In fact, a randomized, controlled, triple-blind study (2009) shows statistically significant results that
Oil pulling therapy has been as equally effective as chlorhexidine against plaque-induced gingivitis. Sesame oil has the following advantages over chlorhexidine: no staining, no lingering aftertaste, and no allergy.
Another randomized, controlled, triple-blind study (2008) shows that oil pulling inhibits growth of Streptococcus mutans, reducing colonies after one week and two weeks of use and yet another study (2011) demonstrates "oil pulling therapy has been equally effective like chlorhexidine against halitosis and organisms which are associated with halitosis."
The connection between oral health and cardiac health has been recognized for decades. Recent research (2012) by the Royal College of Surgeons in Ireland found that if Streptococcus gordonii, which naturally resides in the mouth, finds its way into the bloodstream it can cause life-threatening blood clots. While the effects of oil pulling are not known with this particular strain, if oil pulling does reduce these colonies, it is helping to improve cardiac and circulatory health.
It's a job half done if one only kills the pathogenic bacteria. Dr. Mercola interviewed a Dr. Brady who emphasized eating fermented vegetables to promote the healthy flora of the gut and mouth.
