Oil pulling has gained significant popularity as a natural oral health remedy in recent years. Proponents claim it can whiten teeth, reduce bad breath, eliminate harmful bacteria, and even treat systemic diseases. But with such wide-ranging claims, many dental professionals question whether oil pulling is legitimate or just another pseudoscience fad. This article examines the scientific evidence behind oil pulling, separating established facts from exaggerated myths to help you make an informed decision about this ancient practice.
What Is Oil Pulling and Where Did It Come From?
Oil pulling involves swishing oil in the mouth for 15-20 minutes to improve oral health
Oil pulling (or oil swishing) is an ancient Ayurvedic practice that originated in India approximately 3,000-5,000 years ago. The procedure involves swishing oil in the mouth for an extended period, typically 15-20 minutes, before spitting it out. Traditionally, sesame oil was used, though coconut oil has become increasingly popular in modern practice due to its pleasant taste and antimicrobial properties.
The term “pulling” refers to the way the oil is worked between the teeth and supposedly “pulls” bacteria, toxins, and impurities from the mouth. According to Ayurvedic medicine, oil pulling is believed to treat or prevent dozens of different health conditions, from oral diseases to systemic ailments like diabetes and asthma.
Oil pulling was popularized in the 1990s by Tummala Koteswara Rao, who claimed it cured his chronic asthma after reading about the practice in an academic paper. The practice gained wider attention in Western countries during the natural health movement of the early 2000s and has since become a staple in many holistic wellness routines.
How to Perform Oil Pulling Correctly
The traditional oil pulling method follows these steps:
- Take approximately one tablespoon (10-15 ml) of oil, preferably sesame or coconut oil
- On an empty stomach, preferably in the morning, put the oil in your mouth
- Swish the oil between your teeth for 15-20 minutes
- During this time, the oil should become thinner and milky white
- Spit out the oil (into the trash, not the sink as it may clog pipes)
- Rinse your mouth thoroughly with warm water
- Brush your teeth as normal
Important: Oil pulling should not replace regular brushing, flossing, or professional dental care. It should be considered a complementary practice to standard oral hygiene routines.
Scientific Evidence: What Research Actually Shows
Despite its ancient origins, scientific research on oil pulling is relatively recent and limited. Let’s examine what peer-reviewed studies tell us about its effectiveness for various health claims.
Effects on Oral Bacteria
Several studies have investigated oil pulling’s effect on oral bacteria:
“Our meta-analysis found that oil pulling may have a beneficial effect on reducing salivary bacterial colony count compared to control groups.”
— Peng et al., Healthcare Journal (2022)
A 2015 study published in the Journal of Contemporary Dental Practice found that coconut oil pulling reduced Streptococcus mutans count in saliva, a major contributor to tooth decay. Another study in the Nigerian Medical Journal showed a 20% reduction in total oral microbial load after 40 days of oil pulling.
Effects on Plaque and Gingivitis
Research on plaque and gingival health shows mixed results:
| Study | Oil Type | Duration | Plaque Reduction | Gingivitis Reduction |
| Asokan et al. (2009) | Sesame | 10 days | 18-30% | 52-60% |
| Peedikayil et al. (2015) | Coconut | 30 days | Significant | Significant |
| Sezgin et al. (2019) | Coconut | 4 days | No significant difference | No significant difference |
| Peng et al. (2022) | Mixed (Meta-analysis) | Varied | No significant difference | No significant difference |
The most recent meta-analysis by Peng et al. (2022) found no significant difference in plaque index and gingival index scores between oil pulling and control groups, contradicting some earlier individual studies that showed positive effects.
Effects on Halitosis (Bad Breath)
A randomized controlled trial published in the Journal of Indian Society of Pedodontics and Preventive Dentistry found that sesame oil pulling was as effective as chlorhexidine mouthwash in reducing halitosis. The study attributed this to oil pulling’s ability to reduce the volatile sulfur compounds responsible for bad breath.
How Might Oil Pulling Work? Proposed Mechanisms
Scientists have proposed several mechanisms to explain how oil pulling might work:
Saponification Theory
The alkali in saliva could hydrolyze fat in the oil, creating a soap-like substance. This “soap” might increase the oil’s surface area and enhance its cleansing action, similar to how soap works to remove dirt.
Mechanical Cleansing
The viscous nature of oil may physically trap bacteria and prevent plaque accumulation and bacterial adhesion to teeth and gums. The mechanical action of swishing also helps dislodge debris.
Antioxidant Effect
Oils like sesame contain antioxidants that may help prevent lipid peroxidation, creating an antibiotic-like effect that could destroy microorganisms and enhance vitamin E action in the oral cavity.
However, these mechanisms remain theoretical, and more research is needed to confirm exactly how oil pulling might produce its observed effects.
Examining Systemic Health Claims: Where Oil Pulling Pseudoscience Begins
While some evidence supports oil pulling’s effects on oral health, claims about systemic benefits are where scientific skepticism intensifies. Proponents claim oil pulling can treat or prevent dozens of conditions, including:
Claims With Some Evidence
- Reduction in oral bacteria
- Improvement in bad breath
- Possible reduction in gingivitis symptoms
- Potential complementary treatment for oral thrush
Claims Lacking Scientific Evidence
- “Detoxification” of the body
- Treatment of diabetes, asthma, or allergies
- Prevention of heart disease
- Hormonal balance
- Improvement of skin conditions
- Strengthening of immune system
“There is no plausible biological mechanism by which oil from the mouth could ‘pull’ toxins from the bloodstream or other parts of the body. The oral mucosa prevents the oil from passing through, limiting any potential effects to the mouth itself.”
— Dr. Sarah Jenkins, Dental Researcher
The scientific consensus is that while oil pulling may have legitimate benefits for oral health, claims about systemic effects lack biological plausibility and supporting evidence. This is where oil pulling crosses from evidence-based practice into pseudoscientific territory.
Expert Perspectives: What Dental Professionals and Ayurvedic Practitioners Say
“As a dentist, I see oil pulling as a potentially beneficial complementary practice, but not a replacement for proven dental hygiene methods. The evidence suggests some benefits for oral bacteria and possibly gingivitis, but patients should maintain regular brushing, flossing, and dental check-ups.”
— Dr. Michael Rodriguez, DDS, American Dental Association Member
“In Ayurvedic medicine, oil pulling is part of a holistic approach to health called ‘dinacharya’ or daily routine. While modern science may not validate all traditional claims, we’ve observed benefits for oral health for thousands of years. The practice connects modern users to ancient wisdom about preventive health care.”
— Vaidya Priya Sharma, Ayurvedic Practitioner
“The scientific community needs to approach traditional practices with both skepticism and respect. Oil pulling shows promise for certain oral health applications, but extraordinary claims require extraordinary evidence. We should continue researching while being honest about what we don’t yet know.”
— Dr. Lisa Chen, PhD, Researcher in Complementary Medicine
Oil Pulling: Myths vs. Facts
Myths
- Oil pulling can “detoxify” your entire body
- It can cure or prevent systemic diseases like diabetes
- Oil pulling can replace regular brushing and flossing
- The longer you swish, the more toxins are removed
- Oil pulling whitens teeth by removing deep stains
- Any type of oil is equally effective
- Results are immediate and dramatic
Facts
- Oil pulling may reduce certain oral bacteria
- It could help with bad breath and gingivitis symptoms
- Oil pulling should complement, not replace, regular dental hygiene
- 15-20 minutes is the recommended duration
- Any whitening effect is likely from removing surface plaque
- Coconut and sesame oils have shown the most promising results
- Benefits typically require consistent practice over weeks
Why Is Oil Pulling Often Labeled as Pseudoscience?
Oil pulling often gets labeled as pseudoscience for several key reasons:
- Exaggerated claims: Proponents often make sweeping health claims that far exceed available evidence
- Lack of biological plausibility: Many claimed mechanisms, especially for systemic effects, contradict established biological principles
- Limited research: Despite some positive studies, the overall body of research remains small and sometimes contradictory
- Anecdotal emphasis: Many claims rely heavily on personal testimonials rather than controlled studies
- Historical rather than evidence-based reasoning: The argument that “it’s been used for thousands of years” doesn’t constitute scientific evidence
However, it’s important to distinguish between the practice itself and the claims made about it. Oil pulling for oral health benefits has some scientific support and shouldn’t be dismissed entirely. It’s the expansive claims about systemic health effects that most clearly fall into pseudoscientific territory.
Understanding Anecdotal Success Stories
Despite scientific skepticism, many people report positive experiences with oil pulling. These anecdotal success stories shouldn’t be dismissed entirely, as they may provide valuable insights:
“I’ve been oil pulling with coconut oil every morning for six months. My dentist has noticed less plaque buildup, and my gums don’t bleed anymore when I floss. I can’t say if it’s doing anything beyond my mouth, but the oral benefits have been real for me.”
— Jamie, 34, Oil Pulling Practitioner
Several factors might explain why people experience benefits even if some claims are unproven:
- Placebo effect: The expectation of benefits can produce real physiological changes
- Increased attention to oral hygiene: People who oil pull may become more conscious of their overall oral health
- Complementary practices: Oil pulling is often adopted alongside other healthy lifestyle changes
- Real but limited benefits: The actual benefits for oral bacteria and gingivitis may be noticeable to users
While anecdotal evidence doesn’t replace scientific research, these experiences suggest that oil pulling may provide real benefits for some individuals, particularly for oral health.

Frequently Asked Questions About Oil Pulling
Does oil pulling whiten teeth?
Oil pulling may help remove surface stains by reducing plaque, potentially resulting in a slightly whiter appearance. However, it cannot change the natural color of teeth or remove deep stains like professional whitening treatments. Any whitening effect is likely due to improved plaque removal rather than a true bleaching action.
Can oil pulling replace brushing and flossing?
No. Scientific evidence strongly supports brushing and flossing as essential practices for oral health. Oil pulling should be considered a complementary practice, not a replacement. Dental professionals unanimously recommend maintaining regular brushing, flossing, and professional dental care even if you incorporate oil pulling into your routine.
How long does it take to see results from oil pulling?
Most studies showing benefits from oil pulling were conducted over periods of 1-4 weeks with daily practice. Anecdotal reports suggest some people notice fresher breath within days, while effects on plaque and gingivitis may take several weeks of consistent practice to become noticeable.
Is coconut oil better than other oils for oil pulling?
Coconut oil has gained popularity due to its pleasant taste and lauric acid content, which has antimicrobial properties. Studies have shown benefits with both coconut and sesame oils. Sesame oil has a longer traditional use in Ayurvedic practice, while coconut oil has shown promising results in more recent studies. Either is appropriate for oil pulling.
Are there any side effects or risks to oil pulling?
Oil pulling is generally considered safe when performed correctly. Rare reported side effects include jaw soreness from prolonged swishing, dry mouth, and excessive salivation. A few cases of lipoid pneumonia have been reported from accidental inhalation of the oil. People with allergies to certain oils should avoid those specific oils for pulling.
Conclusion: Balancing Tradition and Science
Oil pulling exists at the intersection of ancient tradition and modern science. The practice itself has some legitimate benefits for oral health, particularly in reducing certain bacteria and potentially helping with bad breath and gingivitis. However, many of the broader health claims lack scientific support and venture into pseudoscientific territory.
A balanced approach recognizes both the potential benefits and limitations of oil pulling. For those interested in natural oral health practices, oil pulling can be a reasonable addition to—never a replacement for—standard dental hygiene practices. Approach it with realistic expectations, focusing on the oral health benefits that have some scientific backing.
As research continues, our understanding of oil pulling’s effects may evolve. Until then, combining respect for traditional practices with scientific skepticism offers the most balanced perspective on this ancient technique. Whether you view oil pulling as a valuable traditional practice or approach it with scientific caution, maintaining this balance helps separate genuine benefits from exaggerated claims.
