Oral health plays a major role in overall wellbeing. The mouth is home to hundreds of types of bacteria, and maintaining a healthy balance of these microorganisms is essential for preventing dental problems such as cavities, plaque buildup, gum disease, and bad breath.
Alongside regular brushing, flossing, and dental checkups, certain traditional practices may help support oral hygiene.
One such practice is oil pulling, an ancient technique that has been used in Ayurvedic medicine for centuries. Ayurveda, the traditional system of medicine that originated in India, emphasizes daily habits that support balance and long-term health. Oil pulling is one of these simple daily rituals.
The practice involves swishing oil in the mouth for several minutes before spitting it out. While it may sound unusual at first, many people use oil pulling as a natural way to support oral hygiene and improve mouth health.
Modern research has also begun exploring this traditional practice, particularly its potential effects on oral bacteria, plaque, and gum health.
In this article, we will explore what oil pulling is, how it works, the potential benefits supported by research, and how you can practice it safely as part of your daily routine.
What Is Oil Pulling?
Oil pulling is a traditional oral hygiene practice that involves swishing oil in the mouth for a period of time, typically 10 to 20 minutes, and then spitting it out. The method has been mentioned in ancient Ayurvedic texts, where it is referred to as “kavala” or “gandusha.”
The practice is simple. A tablespoon of oil—most commonly coconut oil, sesame oil, or sunflower oil—is swished around the mouth, pulled between the teeth, and moved throughout the oral cavity.
According to Ayurvedic tradition, oil pulling helps cleanse the mouth and support oral health by removing impurities. It is often recommended as part of a morning routine before brushing the teeth.
In modern times, oil pulling has gained popularity as a natural oral care method. Many people incorporate it into their daily routine as a complement to brushing and flossing.
Although oil pulling should not replace standard dental care, some studies suggest it may help reduce harmful bacteria in the mouth and support overall oral hygiene when used consistently.
How Oil Pulling Works
The idea behind oil pulling is based on how oil interacts with bacteria and other substances in the mouth.
Many bacteria found in the mouth have a lipid (fat) outer layer. Because oil is also a fat-based substance, it can bind with these bacteria when swished around the mouth. As the oil moves between the teeth and across the gums, it may help trap bacteria and other debris.
When the oil is finally spit out, some of these bacteria and particles are removed from the mouth along with it.
Another possible explanation involves emulsification. As oil mixes with saliva during swishing, it becomes thinner and spreads more easily throughout the mouth, allowing it to reach areas between teeth and along the gum line.
This mechanical action—similar to mouth rinsing—may help loosen plaque and reduce microbial buildup.
While oil pulling is not a substitute for brushing or flossing, it may act as an additional step that supports oral hygiene when combined with proper dental care.
Benefits of Oil Pulling
Below are some of the most commonly reported oral health benefits associated with oil pulling.
May Help Reduce Oral Bacteria
The mouth naturally contains a large number of bacteria, both beneficial and harmful. However, when harmful bacteria grow excessively, they can contribute to dental problems such as cavities, gum disease, and plaque buildup.
Several small studies have explored the effects of oil pulling on oral bacteria. Research suggests that regularly swishing oil in the mouth may help reduce the number of Streptococcus mutans, a bacterium commonly associated with tooth decay.
A 2020 review of four studies involving 182 participants found that oil pulling with coconut oil for 7–14 days significantly reduced oral bacteria and plaque levels. However, the evidence was limited and the quality of studies varied.
Similarly, a meta-analysis of nine studies also reported that oil pulling significantly reduced salivary bacteria levels. However, it did not show clear improvements in plaque or gum inflammation, and researchers noted that better-designed studies are still needed.
Although more research is needed, these findings suggest that oil pulling may help support oral hygiene by lowering bacterial load in the mouth.
May Help Reduce Plaque
Plaque is a sticky film that forms on the teeth when bacteria combine with food particles and saliva. If plaque is not removed regularly through brushing and flossing, it can harden into tartar and increase the risk of gum disease and cavities.
Some research suggests that oil pulling may help reduce plaque buildup when practiced consistently. The mechanical action of swishing oil through the teeth and around the gums may help clean areas that are difficult to reach.
A study of 40 adults compared daily oil pulling with sesame oil to rinsing with distilled water. Participants swished the assigned liquid for 15 minutes every morning for eight weeks. Sesame oil reduced plaque more than water, especially between teeth.
However, the study was small, so more research is needed to confirm the results.
Even so, oil pulling should be used alongside regular brushing and flossing, not as a replacement.
May Support Gum Health
Healthy gums are essential for maintaining strong teeth and overall oral health. When harmful bacteria accumulate along the gum line, they can cause inflammation, bleeding, and gum disease.
Some studies have suggested that oil pulling may help reduce signs of gum inflammation, such as redness and swelling.
A study of 45 schoolchildren aged 10–12 compared probiotic mouthwash, chlorhexidine mouthwash, and sesame oil pulling for 30 days. All three methods significantly reduced plaque and gum inflammation, suggesting that oil pulling may help support gum health.
The potential benefit may come from oil pulling’s ability to reduce harmful bacteria in the mouth. When bacterial levels decrease, the gums may experience less irritation.
Additionally, the gentle swishing action may help massage the gums and improve circulation in the gum tissue.
Although oil pulling alone cannot treat gum disease, it may serve as a supportive practice that helps maintain a cleaner oral environment when combined with good dental hygiene.
May Help With Bad Breath
Bad breath, also known as halitosis, is often caused by bacteria in the mouth that produce unpleasant-smelling compounds.
These bacteria tend to accumulate on the tongue, teeth, and along the gum line, especially when oral hygiene is inadequate.
In several studies, oil pulling was found to reduce halitosis and the bacteria associated with bad breath. The results were comparable to chlorhexidine mouthwash, a commonly used antimicrobial rinse.
Research also suggests that oil pulling may reduce volatile sulfur compounds, which are the primary substances responsible for oral malodor.
As the oil is swished around the mouth and between the teeth, bacteria and food particles may become trapped in the oil and removed when it is spit out, which may help improve breath freshness.
For people who struggle with persistent bad breath, oil pulling may be a simple addition to a daily oral hygiene routine. However, it should not be considered a medical treatment for halitosis.
How to Do Oil Pulling
Oil pulling is simple and can easily be incorporated into a daily routine.
Here is a step-by-step guide:
- Choose an oil.
Coconut oil is the most commonly used oil because of its pleasant taste and natural antimicrobial properties. Sesame oil and sunflower oil are also traditional options. - Take one tablespoon of oil.
Place the oil in your mouth without swallowing it. - Swish the oil gently.
Move the oil around your mouth and pull it between your teeth for about 10–20 minutes. Avoid vigorous swishing, as this may cause jaw fatigue. - Spit the oil out.
Spit the oil into a trash bin rather than the sink, as oil can solidify and clog pipes. - Rinse your mouth.
Rinse with warm water and then brush your teeth as usual.
Many people practice oil pulling first thing in the morning before eating or drinking. Consistency is key, and regular practice may provide better results over time.
Possible Risks
Oil pulling is generally considered safe for most people when practiced correctly. However, there are some limitations to keep in mind.
First, oil pulling should never replace brushing, flossing, or professional dental care. It is best used as an additional step in an oral hygiene routine rather than a primary treatment.
Second, swallowing the oil used during oil pulling should be avoided. The oil may contain bacteria and toxins that have been removed from the mouth.
Some people may also find the practice uncomfortable at first, especially when swishing oil for an extended period. Starting with a shorter duration and gradually increasing the time may make the practice easier.
In rare cases, accidentally inhaling oil during oil pulling may cause respiratory irritation. Swishing gently and avoiding talking during the practice can help reduce this risk.
Anyone with existing dental problems or medical concerns should consult a dentist or healthcare professional before adding new oral care practices.
Conclusion
Oil pulling is a traditional Ayurvedic practice that has gained modern attention as a natural way to support oral hygiene. By swishing oil in the mouth, it may help reduce harmful bacteria, support gum health, decrease plaque buildup, and improve breath freshness.
While research on oil pulling is still evolving, current studies suggest it may offer supportive benefits for oral health when practiced consistently.
However, oil pulling should always complement—not replace—essential habits such as brushing, flossing, and regular dental checkups.
When used as part of a balanced oral care routine, this simple daily practice may help maintain a cleaner mouth and contribute to better long-term oral health.
