Oil pulling is an alternative medical practice in which an edible oil is swished around the mouth for a period of time and then spat out, similar to mouthwash.[1] It originates from Ayurvedic medicine.
Practitioners of oil pulling claim it is capable of improving oral health.[2] Its promoters claim it works by pulling out toxins,[1] but there is no credible evidence to support this.[1][3][4][5]
History
[edit]Oil pulling stems from traditional Ayurvedic medicine,[1][6][7][8] whose practitioners may use sunflower oil, olive oil, or other herbal oils instead of coconut oil.[1][9]
Criticism
[edit]There is no high-quality research on oil pulling,[1][3][5] no understanding of a possible mechanism explaining how it would work,[10] and no evidence that it provides any benefit.[1][4][5] The American Dental Association agrees that there are no reliable scientific studies supporting the practice of oil pulling for any benefit to oral hygiene or overall wellbeing.[11]
The Canadian Dental Association assessed the practice of oil pulling in 2014 stating: "We sense oil pulling won't do any harm, we're not convinced there are any particular benefits to it."[12]

Oil pulling is a suggestive misnomer, implying that something bad is being pulled from the mouth (toxins and bacteria). What little scientific evidence exists shows that it is probably not as effective as standard mouth wash, and what benefit it has is likely entirely due to the mechanical act of swishing to remove particles and bacteria from teeth and gums ... Oil pulling for general health or any other indication is pure pseudoscience. Detox claims are based on nothing, as are all detox claims. There is no evidence or plausible rationale to recommend oil pulling for any indication other than as a poor substitute for oral care.

Oil pulling
View on Grokipediafrom Grokipedia
Oil pulling is an ancient Ayurvedic dental technique originating from India, involving the swishing of edible oil, such as sesame or coconut oil, in the mouth for 15–20 minutes to purportedly improve oral hygiene and reduce harmful bacteria.[1][2] Documented in classical texts like the Charaka Samhita and Sushruta Samhita as kavala or gandoosha, it has been practiced for centuries as a holistic remedy believed to detoxify the body and treat various ailments, though modern interest surged in the 1990s through advocacy by Ukrainian physician F. Karach.[1]
Proponents claim oil pulling reduces plaque, gingivitis, bad breath, and salivary bacterial counts like Streptococcus mutans, while also whitening teeth and alleviating dry mouth, positioning it as a natural adjunct to conventional oral care.[2][3] Systematic reviews and meta-analyses indicate low-quality evidence for modest oral health benefits, particularly in reducing gingivitis, with mixed results for plaque and bacterial counts. A 2022 meta-analysis of nine RCTs (344 participants) found significant reductions in salivary bacterial colony counts versus controls (mean difference: 17.55 CFU/mL; 95% CI: 2.56–32.55), but no notable effects on plaque index (mean difference: -0.10; 95% CI: -0.33–0.14) or gingival index (mean difference: -0.05; 95% CI: -0.12–0.02).[2] However, a 2023 meta-analysis of 25 RCTs (1,184 participants) reported no significant bacterial reductions and chlorhexidine superiority for plaque, with probable benefits for gingival health versus non-chlorhexidine mouthwashes; a 2025 meta-analysis of nine RCTs similarly showed significant gingival improvements versus chlorhexidine but nonsignificant plaque effects.[4][5] Earlier reviews noted comparable short-term plaque reductions to chlorhexidine (up to 50% with coconut oil over 30 days in some trials), emphasizing oil pulling's supplementary role.[1] Oil pulling is one of several natural remedies studied for reducing plaque and gingivitis symptoms, alongside saltwater rinses, aloe vera mouthwash, tea tree oil, turmeric/curcumin, and green tea, with supportive evidence of similar modest efficacy often comparable to chlorhexidine in certain aspects, though evidence quality is generally low to moderate and no high-quality direct head-to-head comparisons establish superiority of any one remedy.[6] Overall evidence remains low due to small sample sizes, short durations (1–45 days), high risk of bias, and inconsistent protocols, with calls for larger, longer-term RCTs.[2][3][4]
Despite these findings, potential risks include aspiration-induced lipoid pneumonia, and the practice is generally safe for adults but not recommended for children under five due to swallowing risks.[7][1] Oils like sesame (rich in antimicrobial sesamol) and coconut (containing lauric acid) are most studied, with no superior oil identified.[7][1]
History
Origins in traditional medicine
Oil pulling, referred to as kavala graha or gandusha in ancient Ayurvedic literature, originates from traditional Indian medicine and is detailed in foundational texts such as the Charaka Samhita and Sushruta Samhita, which date from approximately the 4th century BCE to the 2nd century CE. These practices involve retaining or swishing medicated oils or decoctions in the mouth to address oral and systemic imbalances, forming a core component of Ayurvedic oral hygiene rituals.[8] In these texts, oil pulling is prescribed specifically for oral detoxification by drawing out accumulated toxins (ama) from the oral cavity and deeper channels, thereby purifying the mouth and preventing the buildup of harmful substances.[9] It is also described as a method to strengthen teeth and gums, enhance jaw firmness, and avert oral diseases such as pyorrhea (periodontitis), bleeding gums, and dental decay by promoting tissue resilience and reducing inflammation.[10][11] Within Ayurveda, oil pulling evolved as a recommended daily ritual, particularly for balancing the vata dosha, which governs movement and dryness in the body; imbalanced vata is believed to contribute to oral dryness, tooth sensitivity, and degenerative conditions, and the practice's lubricating effects help mitigate these by nourishing oral tissues and stabilizing doshic harmony.[12] Over time, it became integrated into broader Ayurvedic dinacharya (daily routines) to support preventive health, emphasizing its role in maintaining oral vitality as part of holistic well-being.[13]Modern adoption and popularization
The modern revival of oil pulling in the late 20th century is credited to Ukrainian physician Dr. F. Karach, who introduced the practice to a broader audience during a 1992 presentation at the conference of the All-Ukrainian Union of Oncologists and Bacteriologists. Karach described oil pulling as a simple detoxification method using edible oils like sunflower or sesame, claiming it could address over 30 systemic illnesses by drawing toxins from the bloodstream through the oral mucosa. His advocacy, based on personal observations and patient outcomes, sparked initial interest among alternative health practitioners in Eastern Europe, though it remained niche outside traditional Ayurvedic circles until the 2000s.[14] The practice gained significant momentum in the West during the early 2000s, propelled by publications that framed it as an accessible wellness ritual. A key milestone was the 2008 release of Oil Pulling Therapy: Detoxifying and Healing the Body Through Oral Cleansing by naturopath and nutritionist Bruce Fife, which detailed the technique's purported benefits and encouraged its daily use for oral and overall health improvement.[15] By the 2010s, oil pulling surged as a trend in wellness blogs and early social media, with sites like Goop and natural health forums promoting it as a natural alternative to conventional oral care, leading to widespread adoption among health-conscious consumers.[16] Integration into holistic dentistry and alternative medicine accelerated in the 2010s, as practitioners began incorporating oil pulling into preventive regimens for its supposed antibacterial properties and support for gingival health.[17] Endorsements from celebrities amplified this shift; for instance, actresses Gwyneth Paltrow and Shailene Woodley discussed its benefits in interviews in 2014, crediting it for brighter teeth and fresher breath.[18][19] By the 2020s, influencers on platforms like TikTok and Instagram, including wellness advocates with millions of followers, further popularized it through viral challenges and testimonials, sustaining its status as a go-to ritual in contemporary self-care up to 2025.[20]Practice
Procedure and technique
Oil pulling, akin to the Ayurvedic practice of kavala graha (swishing a smaller amount of oil to draw out toxins), though related to gandusha (holding a full mouth of oil without swishing to strengthen tissues), involves swishing a measured amount of edible oil in the mouth to cleanse the oral cavity.[9][13] The modern technique, following kavala, is performed by gently pulling and pushing the oil through the teeth and around the gums without gargling or swallowing.[21] The standard procedure follows these steps:- Begin on an empty stomach, ideally in the morning, by taking approximately 1 tablespoon (10-15 ml) of oil into the mouth.[13]
- Swish the oil vigorously but gently between the teeth and throughout the oral cavity for 10-20 minutes, or until the oil becomes thin and milky in consistency.[23]
- Spit the oil into a trash receptacle to avoid clogging drains, taking care not to swallow it as it may contain bacteria and toxins.[21]
- Rinse the mouth thoroughly with warm water, followed by brushing the teeth and flossing as part of regular oral hygiene.[13]
Types of oils used
In traditional Ayurvedic practice, sesame oil, known as til taila, is the primary oil recommended for oil pulling due to its warming, nourishing properties and deep penetration into tissues.[13] It contains lignans such as sesamin, sesamolin, and sesaminol, along with vitamin E and polyunsaturated fatty acids, which contribute to its antibacterial and anti-inflammatory qualities.[13] These attributes make sesame oil suitable for balancing vata dosha and supporting oral detoxification in ancient texts.[24] Modern adaptations of oil pulling frequently incorporate coconut oil as a popular alternative, valued for its high lauric acid content—approximately 50% of its fatty acids—which exhibits antimicrobial effects against oral pathogens.[25][26] Sunflower oil and olive oil are also commonly used, with sunflower oil providing neutral taste and vitamin E for mild antioxidant support, while olive oil offers anti-inflammatory oleic acid.[1] These oils are selected for their compatibility with the swishing technique, though coconut oil's solid-to-liquid transition at body temperature enhances ease of use.[25] When choosing oils for oil pulling, organic and unrefined (cold-pressed) varieties are preferred to preserve natural compounds like medium-chain fatty acids and antioxidants, which may be diminished in refined versions.[1] Essential oils should be avoided, as they are concentrated and not intended for prolonged oral swishing, potentially causing irritation.[27]Purported Benefits
Oral health claims
Oil pulling, known as kavala or gandusha in Ayurvedic tradition, is claimed to promote oral health by reducing plaque buildup through the binding of oral bacteria and toxins to the oil, which are then expelled upon spitting.[13] This mechanism is said to decrease the adherence of harmful microbes to teeth and gums, thereby limiting the formation of dental plaque.[28] Traditional sources assert that regular oil pulling alleviates gingivitis and gum inflammation by soothing irritated tissues and preventing bleeding gums, attributed to the oil's lubricating and detoxifying effects on the oral cavity.[8] It is also purported to improve halitosis by eliminating odor-causing bacteria and volatile compounds accumulated in the mouth.[13] Additionally, oil pulling is believed to contribute to teeth whitening by removing surface stains and toxins that dull the enamel, resulting in a brighter appearance over time.[29] Anecdotal reports and traditional Ayurvedic texts, such as the Charaka Samhita, describe it as a preventive measure against cavities by strengthening enamel and reducing susceptibility to decay through enhanced oral hygiene.[30] These practices emphasize the overall fortification of teeth, gums, and jaws for long-term dental resilience.[28]Systemic health claims
Proponents of oil pulling, rooted in Ayurvedic traditions, assert that the practice facilitates detoxification of the body by drawing toxins through the oral mucosa into the oil, which is then expelled, thereby purifying the bloodstream and lymphatic system.[30] This mechanism is believed to support overall holistic balance as described in ancient texts like the Charaka Samhita, where oil pulling (known as Kavala or Gandusha) is prescribed to eliminate impurities that accumulate from daily metabolic processes.[13] Advocates claim that this detoxification process leads to improvements in various systemic conditions, such as headaches and migraines, by alleviating underlying toxic buildup affecting the nervous system.[13] Similarly, skin issues like acne are said to benefit from enhanced purification, resulting in clearer complexion through reduced inflammation and hormonal imbalances linked to toxin overload.[31] For digestive problems, oil pulling is purported to aid in resolving issues like indigestion or metabolic disturbances by promoting better assimilation and elimination of waste, aligning with Ayurveda's emphasis on interconnected bodily systems.[30] From an Ayurvedic holistic perspective, oil pulling is credited with bolstering the immune system by fostering a toxin-free environment that strengthens natural defenses against pathogens.[30] Traditional claims extend to the reduction or prevention of chronic diseases, with the Charaka Samhita suggesting it can address up to 30 systemic illnesses, including asthma and diabetes, through sustained practice that harmonizes the body's doshas (vital energies).[13]Scientific Research
Evidence on oral health effects
Research on oil pulling's effects on oral health has primarily focused on its potential to reduce bacterial loads, plaque accumulation, and gingival inflammation through randomized controlled trials (RCTs) and meta-analyses conducted between 2008 and 2025. Early studies, such as Asokan et al. (2008), demonstrated that oil pulling with sesame oil significantly reduced Streptococcus mutans counts in plaque among adolescents after 2 weeks, with notable decreases observed after 1 week (p=0.01) and 2 weeks (p=0.008), though less effective than chlorhexidine mouthwash.[32] A 2018 RCT using coconut oil reported a 39% reduction in salivary S. mutans counts and a 45% reduction in total bacterial counts after 2 weeks, showing no significant difference compared to 0.12% chlorhexidine (60% and 53% reductions, respectively).[33] Regarding gingivitis, short-term trials have shown positive outcomes comparable to chlorhexidine. A 2023 meta-analysis of 25 RCTs involving 1,184 participants found oil pulling significantly improved the Modified Gingival Index (standardized mean difference [SMD] = -1.14; 95% CI: -1.31 to -0.97) compared to non-chlorhexidine controls over 7–45 days, though chlorhexidine was superior for plaque index reduction (SMD = 0.33; 95% CI: 0.17 to 0.49).[4] A 2024 RCT with sesame oil further supported plaque reduction, achieving an 18.98% decrease in the Rustogi Modified Navy Plaque Index after 8 weeks (p=0.023) versus 10.49% with distilled water control, alongside modest gingival bleeding index improvements (5.13%).[34] A 2025 RCT on sesame-based oil pulling reported significant decreases in both plaque and gingival indices after eight weeks of intervention.[35] In the broader context of natural remedies for gingivitis, other agents such as saltwater rinses, aloe vera mouthwash, tea tree oil, turmeric/curcumin, and green tea have also been investigated and show supportive evidence from RCTs and systematic reviews for reducing plaque, gingival inflammation, and bacterial counts, with efficacy often comparable to chlorhexidine in some aspects (e.g., gingival health improvements) but varying across studies. For example, aloe vera has demonstrated beneficial effects on plaque and gingival indices comparable to or as a potential alternative to chlorhexidine,[36] curcumin mouthwashes have shown comparable anti-plaque and anti-gingivitis properties with no significant differences from chlorhexidine,[37] green tea has exhibited medium positive effects on gingival and plaque indices as well as other periodontal parameters,[38] and tea tree oil has shown some adjunctive benefits with fewer adverse events compared to chlorhexidine.[39] However, no high-quality head-to-head comparative studies directly compare coconut oil pulling or other forms of oil pulling to these alternatives to establish superiority. All such natural approaches are considered adjuncts to standard oral hygiene practices, with evidence quality generally low to moderate due to similar limitations (small sample sizes, short durations, risk of bias). Despite these results, limitations persist across the evidence base. A 2022 meta-analysis of nine RCTs (344 participants) highlighted small sample sizes (typically 20–40 per group), short durations (2–8 weeks), and high heterogeneity, noting significant overall salivary bacterial reductions (mean difference = 17.55; 95% CI: 2.56–32.55; p=0.02) but no consistent effects on S. mutans specifically or gingival indices.[2] Reviews up to 2023 and 2025 emphasize the need for larger, longer-term RCTs to address biases, publication issues, and inconsistent methodologies.[4][35]Evidence on systemic effects and limitations
Research on the systemic effects of oil pulling, such as detoxification, immune system enhancement, or relief from chronic conditions like diabetes and arthritis, remains limited and inconclusive. Traditional claims suggest that oil pulling can draw toxins from the bloodstream and address over 30 systemic illnesses by activating salivary enzymes and reducing inflammation, but no high-quality randomized controlled trials (RCTs) have substantiated these benefits as of 2025.[1] A review in the Journal of Traditional and Complementary Medicine highlights these purported mechanisms but notes the absence of robust clinical evidence beyond oral health improvements.[1] Similarly, authoritative sources like the American Dental Association state that there is insufficient research to support non-oral health claims, including toxin elimination or broader physiological benefits.[40] Methodological limitations plague the existing body of oil pulling studies, undermining confidence in any potential systemic impacts. Key issues include heterogeneity in protocols—such as varying oil types (e.g., sesame vs. coconut), swishing durations (10–20 minutes), and frequencies (daily vs. multiple times)—which complicates comparisons across trials.[2] Many studies suffer from small sample sizes, short intervention periods (often 7–30 days), and inadequate controls for placebo effects, where participants' expectations may influence subjective outcomes.[4] Publication bias is evident in meta-analyses, with Egger's tests indicating a tendency to report positive oral results while negative or null systemic findings go unpublished.[4] Overall, oil pulling has not demonstrated superiority to standard oral hygiene practices like brushing and flossing, even for confirmed oral benefits, further questioning its value for systemic applications.[2] Future research should prioritize large-scale, long-term RCTs to assess systemic markers, such as levels of C-reactive protein (CRP) for inflammation or immune response indicators like cytokine profiles.[1] Such studies could clarify whether reductions in oral pathogens translate to measurable physiological changes, addressing current gaps in evidence quality and protocol standardization.[4]Safety and Criticism
Potential risks and side effects
Oil pulling, while generally considered safe for most individuals when performed correctly, can lead to several common side effects primarily related to the physical demands of the practice. Prolonged swishing of oil in the mouth for 10–20 minutes may cause jaw fatigue or soreness, headaches, tooth sensitivity, dry mouth, or initial nausea, particularly among beginners; these effects often subside with consistent use over one to two weeks.[41][42] In rare cases, accidental swallowing of the oil can result in stomach upset, diarrhea, or aspiration into the lungs, potentially leading to lipoid pneumonia, a serious condition involving inflammation from lipid accumulation.[42][43] Certain individuals should avoid oil pulling due to specific contraindications that could exacerbate existing conditions. It is not recommended for children under 5 years old because of the high risk of aspiration or choking during swishing.[1] Additionally, individuals with allergies to common oils like coconut or sesame should refrain from using them to prevent allergic reactions ranging from mild irritation to severe responses.[41][42] Hygiene practices are crucial to minimize risks during oil pulling. The used oil becomes laden with oral bacteria after swishing, so it must be spat out properly—ideally into a trash bin rather than a sink or toilet to avoid clogs—and never swallowed to prevent ingestion of contaminants.[42] Always use edible-grade or food-safe oils, such as cold-pressed organic varieties of coconut, sesame, or sunflower oil, to ensure they are free from harmful additives or contaminants that could pose additional health risks if trace amounts are ingested.[1][44] Consulting a dentist before starting is advisable, especially for those with pre-existing oral conditions, to tailor the practice safely.[41]Expert critiques and regulatory views
The American Dental Association (ADA) has consistently stated that there is insufficient scientific evidence to support oil pulling as an effective oral hygiene practice, emphasizing that it should not replace proven methods like brushing with fluoride toothpaste twice daily and flossing.[45] The ADA advises against using oil pulling as a substitute for evidence-based dental care, noting that no reliable studies demonstrate its ability to reduce cavities, whiten teeth, or improve overall oral health.[46] Similarly, the British Dental Journal has critiqued oil pulling as "bad science," highlighting the absence of evidence for its purported benefits such as preventing cavities, detoxifying the body, or treating conditions like cancer, despite widespread online claims.[47] Experts in evidence-based medicine, including those from Science-Based Medicine, have labeled oil pulling as pseudoscience, particularly when promoted as a universal remedy for oral and systemic ailments, arguing that it distracts from established treatments and may lead individuals to delay seeking professional dental care for issues like plaque buildup or gum disease.[48] Dental professionals warn that reliance on such unproven practices could exacerbate oral health problems by forgoing fluoride use and regular check-ups, potentially resulting in worsened conditions over time.[49] From a regulatory perspective, the U.S. Food and Drug Administration (FDA) does not approve oil pulling as a medical treatment, classifying products marketed with therapeutic claims—such as reducing bacteria or improving health—as unapproved new drugs in violation of federal law.[50] In 2025, the National Advertising Review Board recommended that companies like GuruNanda discontinue unsubstantiated claims about oil pulling products whitening teeth or providing dental benefits, underscoring concerns over misleading wellness marketing that positions it as a cure-all without supporting data.[51] Health authorities, including the ADA, echo these regulatory cautions by urging consumers to avoid products or practices hyped for unverified systemic effects, prioritizing instead scientifically validated oral care routines.[44]References
