Most dentists do not recommend oil pulling as a standard part of oral care. The American Dental Association has not endorsed the practice, citing insufficient high-quality evidence to support it as a reliable treatment. While some small clinical studies show promising results, the overall body of research remains too limited for major dental organizations to give it a green light.
Where the ADA Stands
The ADA’s position on oil pulling falls under its broader policy on complementary and alternative medicine. The organization holds that any dental treatment, whether conventional or alternative, should meet the same standards of scientific evidence before being recommended. Oil pulling hasn’t cleared that bar. The ADA considers it an “understudied intervention” that needs further testing before reliable conclusions can be drawn about its safety, effectiveness, and benefits beyond a placebo effect.
This doesn’t mean the ADA has declared oil pulling harmful or useless. It means the evidence isn’t strong enough, in their view, to recommend it alongside brushing, flossing, and antimicrobial mouthwash. Most practicing dentists follow this guidance: they won’t discourage you from trying it, but they won’t suggest it as a replacement for anything in your current routine.
What the Research Actually Shows
The clinical studies that do exist are small but genuinely interesting. In one trial, participants who swished coconut oil daily saw their plaque index drop from 1.19 to 0.385 over 30 days, with gingival (gum inflammation) scores falling from 0.91 to 0.401. Both reductions were statistically significant. A separate randomized controlled trial comparing sesame oil pulling, chlorhexidine mouthwash (the clinical gold standard), and probiotic mouthwash in children aged 10 to 12 found all three were equally effective at reducing plaque and improving gum health.
Those results sound compelling, and they are. The problem is scale and quality. Systematic reviews that pool all available studies together consistently find the evidence is low certainty. Most individual trials have small sample sizes, short durations, and a high or unclear risk of bias in their design. One major review concluded that the quality of evidence is too low to recommend oil pulling as even a supplement to conventional oral hygiene, let alone a replacement.
How Oil Pulling Works Mechanically
Oil pulling isn’t purely a placebo, though. Laboratory research has identified two physical processes that explain its cleaning effect. When you swish oil vigorously in your mouth for several minutes, it undergoes emulsification, meaning it breaks into tiny droplets that can surround and lift bacteria and debris from tooth surfaces. There’s also evidence of saponification, a soap-like chemical reaction that occurs when the oil interacts with saliva’s alkaline components. Together, these processes enhance the mechanical cleaning action of the swishing itself.
Notably, the antibacterial compounds in sesame oil (sesamin and sesamolin) showed no direct killing effect on common oral bacteria like Streptococcus mutans, the primary driver of cavities. So the benefit appears to come from physically dislodging bacteria rather than chemically destroying them.
Risks Worth Knowing About
Oil pulling is generally considered low risk, but it’s not risk-free. The most serious documented complication is lipoid pneumonia, a lung condition caused by accidentally inhaling or aspirating oil into the airways. Published case reports describe two patients who developed this condition after months of regular sesame oil pulling. One had been pulling oil through nasal passages (not the standard technique), and the other swished it orally but occasionally aspirated small amounts. Acute cases of lipoid pneumonia can be severe or even fatal, though chronic cases often produce minimal symptoms.
The risk is highest for people who have difficulty controlling swallowing, such as young children or older adults with swallowing disorders. If you try oil pulling, keeping the volume of oil small (about a tablespoon) and staying upright during the process reduces the chance of aspiration.
How to Do It Safely
If you want to try oil pulling as an add-on to your routine, the typical approach involves swishing a tablespoon of oil (coconut, sesame, or sunflower are most common) around your mouth for anywhere from 5 to 20 minutes. Most practitioners suggest doing it on an empty stomach, first thing in the morning, before brushing. When you’re done, spit the oil into a trash can rather than the sink or toilet, since it can clog plumbing. The used oil will look thin, white, and slightly foamy.
Twenty minutes is a long time to swish anything. If you’re new to it, starting with 5 minutes and working up is more realistic. The oil should never be swallowed, as it contains the bacteria and debris you’ve just pulled from your teeth and gums.
The Bottom Line for Your Routine
Oil pulling sits in a gray zone: not debunked, but not proven well enough for professional endorsement. The small studies that exist suggest it can reduce plaque and gum inflammation, potentially on par with mouthwash. But no large, high-quality clinical trial has confirmed these findings, and no major dental organization recommends it. Brushing twice a day with fluoride toothpaste, flossing daily, and using an antiseptic mouthwash remain the evidence-backed foundation of oral care. If oil pulling appeals to you, treating it as an extra step rather than a substitute for any of those three is the approach most dentists would be comfortable with.
