Oil pulling with coconut oil is simple: you swish a tablespoon of it around your mouth for 15 to 20 minutes, then spit it out. That’s the core of it. But the details matter, from how to work up to that full duration to what you do afterward, so here’s everything you need to get it right.
Step-by-Step Instructions
Start first thing in the morning, before eating or drinking anything. Measure out one tablespoon of coconut oil and place it in your mouth. If it’s solid (coconut oil hardens below about 76°F), let it melt on your tongue for a few seconds before you begin swishing.
Gently push and pull the oil between your teeth, swirl it around your gums, and move it across all surfaces of your mouth. Think of it like a slow, relaxed mouthwash, not a vigorous gargle. You don’t need to use force, and keeping a gentler pace will prevent jaw fatigue over the full session. Avoid tilting your head back or gargling, since you don’t want oil reaching your throat.
The target is 15 to 20 minutes. If that sounds like a lot, start with 5 or 10 minutes and gradually increase as you get comfortable. Most people oil pull while doing something else: showering, making breakfast, scrolling their phone. It becomes less noticeable when you’re not watching the clock.
When you’re done, spit the oil into a trash can or a lined container. Don’t spit it into the sink or toilet. Coconut oil solidifies at cool temperatures and will coat and clog your pipes over time. If some does go down the drain, flush it immediately with boiling water to push it through before it hardens. After spitting, rinse your mouth with warm water, then brush and floss as you normally would. Oil pulling works best as a pre-brushing step, not a replacement for brushing.
Why Coconut Oil Specifically
You can oil pull with sesame oil, sunflower oil, or other options, but coconut oil has a specific advantage: it’s roughly 50% lauric acid, a medium-chain fatty acid with well-documented antimicrobial and anti-inflammatory properties. Lauric acid is also found in high concentrations in human breast milk, where it serves a similar protective function.
During oil pulling, lauric acid reacts with the sodium hydroxide naturally present in saliva to form sodium laureate, which is essentially the main ingredient in soap. This saponification process, along with the physical emulsification of the oil as you swish, gives the practice a genuine mechanical cleaning effect. It’s not just moving liquid around. The oil thickens and turns milky white as it emulsifies, trapping bacteria and debris in the process.
Coconut oil also contains a compound called monolaurin. Electron microscopy has shown that 15 minutes of monolaurin exposure causes certain oral bacteria to physically shrink and disintegrate. Another coconut oil component, sucrose monolaurate, interferes with the way cavity-causing bacteria process sugars, reducing their ability to form plaque.
What the Evidence Actually Shows
The strongest evidence for oil pulling relates to plaque and gum inflammation. In a randomized crossover trial comparing coconut oil pulling to chlorhexidine (a prescription-strength antimicrobial mouthwash), the two performed nearly identically at inhibiting plaque regrowth. Gum inflammation and bleeding scores were also similar between the groups. Notably, oil pulling produced significantly less tooth staining than chlorhexidine, which is known for leaving brown or yellow deposits on teeth over time.
Oil pulling also appears to reduce the bacteria responsible for bad breath. Oral malodor is driven by specific microbes that produce volatile sulfur compounds like hydrogen sulfide and methyl mercaptan. Oil pulling helps reduce these bacterial populations, which is why many people notice fresher breath as one of the first benefits.
The teeth whitening claim is harder to support. The American Dental Association states there are no reliable scientific studies showing that oil pulling whitens teeth. Any perceived whitening likely comes from reduced plaque buildup making teeth look cleaner, not from any bleaching or shade-changing effect on the enamel itself.
What the ADA Says
The American Dental Association does not recommend oil pulling as a dental hygiene practice. Their position is that there isn’t enough reliable evidence to confirm it reduces cavities, whitens teeth, or improves overall oral health. The ADA continues to recommend brushing twice daily for two minutes with fluoride toothpaste and flossing once a day.
That said, the ADA’s stance reflects the absence of large-scale, long-term clinical trials rather than evidence of harm. Smaller studies have shown measurable effects on plaque and gingivitis, and dental professionals at Tufts University have noted they wouldn’t discourage patients from using oil pulling as a pre-brushing rinse, as long as it’s followed by standard brushing and flossing. The key point: it’s an addition to your routine, not a substitute for it.
Risks to Be Aware Of
Oil pulling is low-risk for most people, but there are a few things to watch for. The most important rule is don’t swallow the oil. After 15 to 20 minutes of swishing, it’s loaded with bacteria and debris pulled from your mouth. Swallowing it defeats the purpose and can cause nausea.
A more serious but rare concern is aspiration, where oil accidentally enters the airway. Lipid pneumonia, a lung inflammation caused by inhaled oil, has been documented in cases where people aspirate fatty substances. This is uncommon, but it’s the reason you should never gargle during oil pulling or tilt your head back while swishing. If you have a strong gag reflex or difficulty controlling liquids in your mouth, use a smaller amount of oil or skip the practice.
Some people experience jaw soreness from the extended swishing, especially in the first week. This usually means you’re swishing too aggressively. Relax your jaw and use gentle, easy movements. If soreness persists, shorten your sessions.
Making It a Consistent Habit
The benefits of oil pulling are cumulative, not instant. Most studies showing measurable changes in plaque and bacteria used protocols lasting at least one to two weeks of daily practice. Pairing it with a morning activity you already do (like making coffee or getting dressed) makes it easier to stick with. Keep a jar of coconut oil and a trash-lined cup near your bathroom sink so there’s no friction in the process.
If you find the texture unpleasant, refined coconut oil has a milder taste and smell than virgin coconut oil, though virgin retains more of the beneficial compounds. Either works. Room temperature or slightly warm coconut oil is easier to start with than a cold, hard spoonful straight from the jar.
