Researchers have known for some time that the same bacteria that are found in your mouth are also found inside arterial plaque and on the valves of the heart. (1,2) These unhealthy bacteria are thought to find their way into the bloodstream through the gums, especially when you have bleeding gums. Flossing and even chewing can irritate gum tissue, cause minor bleeding and open the door for bacteria exposure and access to the heart and arteries. (2)
There is plenty of evidence linking common undesirable mouth bacteria like Streptococcus mutans to a host of health concerns which include arterial, heart, lung and blood sugar health. (1) The prevalence of finding S. mutans is very high compared to other oral bacteria. In one report, S. mutans was found in 69 percent of heart valve cases and 74 percent of arterial plaque specimens. (2)
Understanding the link between the potential pathogenic bacteria in the mouth and your overall health cannot be understated. While dentists are adamant regarding oral hygiene, few of their preventative strategies actually reduce the population of mouth S. mutans in the mouth.
Ayurveda has been recommending a daily oral hygiene strategy for thousands of years that has been recently shown to reduce S. mutans, support healthy gums and reduce plaque. Oil pulling is a technique where sesame and coconut oil are swished inside the mouth for 10-15 minutes daily. (3-5,7) This is best performed after tongue scraping, brushing and flossing, and can be done while showering.
Studies show that the swishing of these oils creates a saponification or detergent effect that deters bad bacteria and plague, while supporting healthy gum tissue as a barrier against bacterial exposure to the bloodstream. (3-5,7)
In one amazing study, when coconut oil was partially digested by swishing in the mouth, it enhanced its antimicrobial effects. In other words, the act of swishing oil in the mouth actually boosts its ability to protect us from undesirable bacterial like S. mutans entering into the bloodstream. (6)
According to a study investigating cognitive decline at the UCLA Buck Institute, good oral hygiene is one of the top 10 keys to longevity. (8) This is one of those examples where an ancient practice, which seems silly or “trendy” by today’s standards, is making a comeback as science continues to validate this practice.
