Oil pulling involves swishing a spoonful of oil, usually coconut or sesame, around your mouth for several minutes before spitting it out. It may help reduce some plaque bacteria and freshen breath for a short time, but it cannot whiten teeth significantly, reverse cavities, cure gum disease or “detox” the body. At best, it is an optional extra alongside brushing with fluoride toothpaste and cleaning between your teeth, never a replacement for them.
Key takeaways
- Oil pulling is a traditional practice of swishing edible oil around the mouth, most often coconut or sesame oil.
- Limited research suggests it may modestly reduce plaque and bad breath, but the evidence is small and of mixed quality.
- It cannot repair cavities, remove tartar, treat gum disease or draw toxins out of the body.
- Brushing twice daily with fluoride toothpaste, cleaning between teeth and regular dental visits remain essential.
- Always spit the oil into a bin rather than the sink, and never swallow it.
What exactly is oil pulling?
Oil pulling is a practice with roots in traditional Ayurvedic medicine, where it was used as part of a daily cleansing routine. The method is simple: you place about a tablespoon of oil in your mouth and swish it slowly between your teeth and around your gums for anywhere from five to twenty minutes. The oil gradually becomes thinner and milky as it mixes with saliva. You then spit it out, rinse your mouth with water and carry on with your usual brushing routine.
In recent years, oil pulling has become popular on social media and wellness blogs, where it is often promoted with bold claims about whiter teeth, healthier gums and whole-body benefits. Coconut oil is the most common choice today because of its mild taste, although sesame and sunflower oils have also been used traditionally. The appeal is easy to understand. It uses an inexpensive, natural ingredient most people already have in the kitchen, and it feels like a calm, mindful ritual to start the day.
How is oil pulling supposed to work?
The idea behind oil pulling is that oil can attach to bacteria and debris in the mouth, loosening them from tooth surfaces so they are spat out with the oil. Plaque bacteria have fatty outer layers, and supporters suggest these are attracted to the oil during swishing. The long, repeated movement of liquid through the gaps between the teeth may also dislodge loose food particles, in a similar way to a vigorous rinse with water or mouthwash.
Coconut oil contains lauric acid, a fatty acid that has shown some antibacterial properties in laboratory studies. Some researchers have suggested that this could explain modest reductions in certain bacteria seen in small trials. However, what happens in a laboratory dish does not always translate to the complex environment of the human mouth, where bacteria live in well-organised, sticky biofilms firmly attached to the teeth. These biofilms are best disrupted by physical cleaning with a brush and interdental cleaners.
What does the research actually say?
A handful of small studies have compared oil pulling with no treatment or with antibacterial mouthwash. Some have reported reductions in plaque, gum inflammation scores or bad-breath measurements over a few weeks. These findings are interesting, but most studies involved small groups of people, ran for short periods and had design limitations that make the results difficult to rely on. Few were carried out in a way that rules out the influence of participants simply paying more attention to their oral hygiene.
Major dental organisations generally do not recommend oil pulling as an oral health treatment, because there is not enough high-quality evidence to show meaningful, lasting benefits. That does not mean it is harmful for most people, but it does mean claims about dramatic results should be treated with caution. If you enjoy oil pulling and it encourages you to take more interest in your mouth, it can sit alongside proven habits. It should simply never replace them.
Can oil pulling whiten your teeth?
Teeth whitening is one of the most common claims made about oil pulling, but there is no good evidence that it can change the natural colour of your teeth. True whitening involves products that break down stain molecules within the enamel, usually under the guidance of a dental professional. Oil does not contain ingredients capable of doing this. Any brighter appearance people notice is more likely to come from removing a little surface debris or from paying closer attention to brushing.
Surface stains from tea, coffee, red wine and tobacco sit on the outer layer of enamel and are mostly removed by regular brushing and professional cleaning. If your teeth have become discoloured, a dental check-up is the best first step, because discolouration can sometimes signal decay, an old filling breaking down or a tooth that has been damaged internally. Your dentist can explain which whitening options are safe and suitable for your teeth and gums.
Can oil pulling treat cavities or gum disease?
Oil pulling cannot repair a cavity. Once decay has broken through the enamel and formed a hole, the damaged tooth structure cannot grow back, and it needs to be treated by a dentist with a filling or other restoration. Fluoride, found in toothpaste and some professional treatments, can help strengthen early weak spots before a cavity forms, but oil contains no fluoride and offers no comparable protection to enamel.
Similarly, oil pulling cannot treat established gum disease. Gum disease is driven by plaque and hardened tartar along and below the gumline. Tartar can only be removed with professional instruments, and deeper gum pockets need careful cleaning by a dentist or hygienist. Relying on oil pulling instead of seeking treatment could allow gum disease to progress quietly, leading to bone loss and loose teeth. Bleeding gums, persistent bad breath or receding gums should always be checked professionally.
What about claims that oil pulling detoxifies the body?
You may see oil pulling promoted as a way to “pull toxins” out of the body, improve skin, ease headaches or support conditions far beyond the mouth. There is no scientific evidence supporting these claims. The body already has highly effective systems for processing and removing waste, mainly through the liver and kidneys. Swishing oil in the mouth does not draw substances out of the bloodstream, and the milky appearance of the oil is simply the result of mixing with saliva.
It is true that oral health and general health are closely linked. Ongoing gum inflammation has been associated with a range of wider health conditions. However, the best way to support that connection is to keep plaque under control through proven daily habits and regular dental care. If you are interested in the mouth-body link, focusing on thorough brushing, cleaning between your teeth, a balanced diet low in frequent sugar, and avoiding tobacco will deliver far more reliable benefits.
Is oil pulling safe?
For most adults, oil pulling is unlikely to cause harm when done occasionally and correctly. Some people experience jaw tiredness from the long swishing time, a temporary upset stomach if small amounts are swallowed, or a dislike of the texture that causes gagging. People with allergies to coconut, sesame or other oils should avoid the relevant oil. Oil pulling is not suitable for young children, who may swallow the oil or struggle to spit it out safely.
There is a small but important risk if oil is accidentally inhaled into the lungs, which can cause a type of lung inflammation. This is rare, but it is a reason to swish gently and avoid oil pulling while lying down or if you have difficulty swallowing. Spit the used oil into a bin or a paper towel rather than the sink, because oil can solidify and block drains over time. Rinse your mouth with water afterwards and continue with your normal brushing.
How can you include oil pulling safely if you want to try it?
If you would like to try oil pulling, treat it as an optional addition rather than a cornerstone of your routine. Use about a teaspoon to a tablespoon of food-grade oil, swish it gently for five to ten minutes, then spit it out. There is no need to push to twenty minutes if it makes your jaw ache. Rinse with water and then brush your teeth for two minutes with fluoride toothpaste, spitting out the toothpaste afterwards rather than rinsing it away.
Keep cleaning between your teeth daily with floss, interdental brushes or another tool recommended by your dental team, as no rinse can fully reach these areas. Attend regular check-ups and professional cleans so that any developing problems are picked up early. If you have dental restorations, gum disease, a dry mouth or other health conditions, mention oil pulling at your next appointment. Your dentist or hygienist can advise whether it is likely to be helpful, neutral or best avoided in your situation.
Frequently Asked Questions
Which oil is best for oil pulling?
Coconut oil is the most popular choice because of its mild flavour, and sesame and sunflower oils have been used traditionally. There is no strong evidence that one oil is clearly better than another for oral health. Choose a food-grade oil you are not allergic to and find comfortable to swish.
Can oil pulling replace brushing my teeth?
No, oil pulling cannot replace brushing. Brushing twice daily with fluoride toothpaste physically removes plaque and strengthens enamel, which oil pulling cannot do. Cleaning between your teeth every day is also essential. If you choose to oil pull, do it in addition to brushing and interdental cleaning, not instead of them.
Does oil pulling help with bad breath?
Some small studies suggest oil pulling may temporarily reduce bad breath, possibly by loosening debris and bacteria. However, persistent bad breath often has an underlying cause such as gum disease, tongue coating, dry mouth or decay. If bad breath does not improve with good brushing, flossing and tongue cleaning, see your dentist.
Is oil pulling safe with fillings, crowns or braces?
Oil pulling is generally unlikely to damage fillings, crowns or braces, but it will not clean around them as effectively as brushing and interdental cleaning. People with dental work should take extra care with their normal cleaning routine. Ask your dentist or orthodontist if you are unsure whether oil pulling suits your situation.
Why should I not spit oil down the sink?
Oils, especially coconut oil, can cool and solidify inside pipes, gradually building up and contributing to blockages. Spitting the used oil into a bin or onto a paper towel is a simple way to avoid this. Afterwards, rinse your mouth with water and brush your teeth as usual with fluoride toothpaste.
