With endorsements coming from celebrities such as Gwyneth Paltrow, you might find it tempting to try oil-pulling – an Indian folk practice that has gained lots of attention in homeopathic circles in recent years.

Oil-pulling is swishing a teaspoon of oil in your mouth for 20 minutes every day, then spitting it out. The traditional oil to use is sesame. But many use coconut oil.
Thousands of YouTube videos extol its purported health benefits. A Google news search brings up thousands of stories – many written very recently.
But the evidence-based bottom line on oil-pulling is this:
- It can’t substitute for brushing twice daily and flossing.
- There’s no evidence it cures anything.
A traditional folk remedy
For centuries, people used this practice every day to prevent tooth decay, bad breath, bleeding gums, throat dryness and cracked lips.
The more enthusiastic proponents of oil-pulling claim it cures everything from a hangover to diabetes or acne.
There is some evidence that oil-pulling, particularly with coconut oil, could inhibit plaque formation, says wellness and preventative medicine specialist Sandra Darling, DO.
- Oil-pulling is as effective as rinsing with mouthwash to maintain and improve oral health, a study from 2008 says. The study examined levels of Streptococcus mutans, a bacteria commonly found in the mouth that causes tooth decay.
- Oil-pulling with sesame oil and mouthwash both reduced gingivitis, says another study from 2009.
- Oil-pulling could be a preventive home therapy to maintain oral hygiene – especially in developing countries, says a study from 2011. The study said however that further research should investigate exactly how oil-pulling works, as well as its long-term effects.
- This traditional practice, when done correctly and regularly, was found to improve oral hygiene, according to a 2017 study. So it should be encouraged since it is inexpensive — alongside regular brushing and flossing.
Again, it’s important to restate that oil-pulling should not take the place of good, consistent dental hygiene, Dr. Darling says. That means brushing twice a day for two minutes and flossing once daily.
No support for other health claims
Oil-pulling is not going to whiten your teeth, clear your sinuses or cure your diabetes, despite what proponents say.
“There is no research to corroborate all of these other health claims,” Dr. Darling says.
“You can make the stretch that oral health can support systemic health – that there are benefits downstream,” she says.
“But to date there is no scientific research that oil-pulling is a direct mechanism of action for these other conditions. And no current evidence suggests that improving oral hygiene alone will improve diabetes or other chronic conditions.”
