Best Oil for Oil Pulling: Coconut vs Sesame vs Sunflower
Which oil to swish, honestly ranked by evidence and by feel.
- For oil pulling, sesame oil is the most-studied choice and the traditional Ayurvedic one; coconut oil is the most popular today and the easiest on the palate.
- Head-to-head trials do not crown a clear winner: sesame and coconut both produce a modest drop in salivary bacteria and behave similarly in the mouth.
- Sesame oil has the single strongest trial, matching chlorhexidine over ten days; coconut oil has its own supportive systematic review; sunflower oil has the least direct evidence.
- No oil whitens enamel, removes established plaque as well as brushing, or beats a proven antiseptic rinse for plaque, so the choice is mostly taste, cost and preference.
- Whichever you pick, use it as an adjunct to fluoride or hydroxyapatite brushing and flossing, and keep your dental visits.
There is no single best oil for oil pulling. Sesame oil has the strongest trial evidence and tradition behind it; coconut oil tastes better and has its own supportive review; sunflower oil is a fine but least-studied alternative. All three give a similar, modest benefit, so choose by taste and cost and use it alongside normal brushing.
What actually separates the oils
When people search for the best oil for oil pulling, they usually hope one oil is meaningfully more effective than the rest. The evidence does not support that hope. All edible oils used for pulling work the same way: as you swish, the oil emulsifies into fine droplets that trap loose bacteria and debris, which you then spit out. The measurable result across studies is a modest reduction in the bacteria carried in saliva, and that result shows up whether the trial used sesame or coconut oil. Where the oils genuinely differ is not in the size of the benefit but in the strength of the evidence behind each one and in how they feel to use. Sesame oil is the oil named in the traditional practice and the one tested in some of the most carefully designed early trials. Coconut oil is the newer favourite, backed by its own small systematic review, and it wins on taste for most people. Sunflower oil appears in the broader literature as an alternative but has attracted far less direct study. So the sensible way to choose is to rank the oils by evidence and by comfort, not by an imaginary difference in power.
Sesame, coconut and sunflower differ in taste and evidence, not in how they work — all rely on the same gentle emulsifying rinse.
What the research actually shows
Every claim below maps to a named, peer-reviewed source in the Sources section. According to PubMed.
| Claim | Evidence | Source |
|---|---|---|
| Sesame-oil pulling reduced plaque, gingival index and colony counts comparably to chlorhexidine over 10 days, the strongest single trial for any pulling oil. | Randomized, triple-blind controlled trial (n=20). | Asokan et al., 2009 |
| Coconut-oil pulling significantly reduced salivary bacterial colony count and plaque score across four small trials, though study quality was mixed and risk of bias high. | Systematic review of 4 RCTs (n=182). | Woolley et al., 2020 |
| Pooling nine trials of different oils, salivary bacterial counts fell significantly, but with no significant advantage over controls for plaque or gingival index. | Meta-analysis of 9 RCTs. | Peng et al., 2022 |
| In the largest synthesis, half the trials used sesame oil; chlorhexidine still controlled plaque better than oil pulling and the overall certainty was very low. | Systematic review and meta-analysis, 25 trials. | Jong et al., 2023 |
| Across five randomized trials, oil pulling showed no significant differences from chlorhexidine or placebo, suggesting the oil chosen matters less than the practice itself. | Systematic review of 5 RCTs (n=160). | Gbinigie et al., 2016 |
The pick guide: coconut vs sesame vs sunflower
| Oil | Best for | Evidence | Verdict |
|---|---|---|---|
| Sesame oil | Tradition and the strongest single trial | Matched chlorhexidine in a triple-blind RCT | Best-studied pick |
| Coconut oil | Taste and everyday palatability | Own systematic review; fewer salivary bacteria | Best for comfort and consistency |
| Sunflower oil | A neutral, inexpensive alternative | Appears in the literature but least directly studied | Fine, but least evidence |
| Any of the three | A low-risk daily adjunct | All give a similar modest benefit | Choose by taste and cost |
How to choose for yourself
Because the oils perform so similarly, the best oil for oil pulling is really the one you will use consistently and comfortably. If you want the choice most backed by tradition and by careful trials, sesame oil is the pick; its nutty taste is stronger, which some people love and others do not. If you care most about a mild, pleasant swish that you can keep up daily, coconut oil is the easy winner, and its lauric acid gives it a plausible extra edge in the laboratory even if trials cannot confirm a real-world difference. Sunflower oil is a reasonable budget or allergy-driven alternative, but you are relying more on the general principle of oil pulling than on evidence for that specific oil. Whatever you choose, buy a plain food-grade oil; there is no evidence that specialty pulling blends, added flavourings or fortified oils outperform the basics. And keep the ceiling in mind: the difference between a good oil and a great one is trivial next to the difference between doing oil pulling instead of brushing, which is a mistake, and doing it alongside brushing, which is the sensible way.

How to pull with your chosen oil
Once you have picked an oil, the routine is the same. None of this treats a disease; it is a clean-feeling adjunct.
- 1
Start with a tablespoon of a plain food-grade oil
—Sesame, coconut or sunflower are all fine. Coconut oil will melt in the mouth within a few seconds if it is solid.
- 2
Swish gently, never gargle or swallow
5 to 20 minutesMove the oil slowly around the mouth and between the teeth. Keep it relaxed, and never swallow it once it holds the debris you are removing.
- 3
Spit into the bin
a few secondsOils can congeal and block drains, so spit into a tissue or the rubbish, then rinse with water.
- 4
Brush and floss afterwards
twice dailyOil pulling leaves firmly attached plaque behind, so follow with your usual fluoride or hydroxyapatite toothpaste and floss.
- 5
Keep your dental check-ups
as advisedNo oil substitutes for professional care. See a dentist for bleeding gums, sensitivity, pain or a spot being watched.
Whichever oil you choose, it belongs alongside brushing and flossing, not in place of them.
No pulling oil is a treatment. See a dentist if your gums bleed regularly, a tooth is sensitive or painful, your breath stays bad despite good hygiene, or you have a spot on a tooth that needs assessment. Do not delay care hoping an oil will reverse a cavity or gum disease. Never swallow the used oil, and take care if you are prone to gagging or have swallowing difficulties.
