There's a good deal of information about "oil pulling" which is the process by which you swish oil around your mouth for 20 minutes or so then spit it out. There are many claims about what it can heal, one of which has been asked about here. More believable claims revolve around tooth and oral health. Of particular note, is coconut oil, which is often the subject and oil of choice when the practice is discussed.
People that “oil pull” state that it has helped whiten their teeth, alleviate halitosis, and even reduce gingivitis. In many cases, people also claim that it helps “prevent” cavities, as well as relieve gum and tooth sensitivity.
Others have suggested that coconut oil toothpaste makes for a powerful and natural alternative to traditional toothpaste.
They found that enzyme-modified coconut oil strongly inhibits the growth of most strains of Streptococcus bacteria, including Streptococcus mutans, an acid-producing bacterium that is a major cause of tooth decay. It is thought that the breaking down of the fatty coconut oil by the enzymes turns it into acids, which are toxic to certain bacteria.
So, I would like to know what studies exist for coconut oil specifically, whether used whole, "enzyme treated", or otherwise, that demonstrate its effectiveness in promoting oral health.
