Oil pulling is one of those wellness practices that keeps cycling back into public conversation, from Ayurvedic tradition to TikTok trends to morning routines that rival a full breakfast ritual. But if you’ve ever wondered whether swishing coconut oil around your mouth for 20 minutes actually does anything meaningful for your oral health, you’re not alone. As interest in natural health practices continues to grow, it’s worth looking at what the science and dental professionals genuinely say, rather than what wellness influencers claim.

Key Takeaways
Oil pulling may slightly reduce plaque and oral bacteria, but research is still limited.
- Dentists and the American Dental Association do not recommend it as a replacement for brushing or flossing.
- Coconut oil is most commonly used because of its antimicrobial properties.
- Oil pulling is generally low-risk, but incorrect use can cause jaw soreness, nausea, or rare lung complications.
- The strongest evidence still supports fluoride toothpaste, flossing, and regular dental visits over alternative oral-care trends.
What Is Oil Pulling, Exactly?
Oil pulling is an ancient Ayurvedic practice that involves swishing a tablespoon of edible oil, most commonly coconut, sesame, or sunflower oil, in the mouth for 10 to 20 minutes before spitting it out.
The practice dates back thousands of years in traditional Indian medicine, where it was used as part of a broader oral hygiene and detoxification approach. In modern practice, coconut oil has become the most popular choice, largely due to its lauric acid content, which has demonstrated antimicrobial properties in laboratory studies. The basic idea is that the oil “pulls” bacteria, debris, and toxins from between the teeth and along the gumline, and then you spit the whole mixture out rather than swallowing it.
Today, oil pulling is often framed as a complement to, or even a replacement for, conventional brushing and flossing. That distinction matters enormously when evaluating both the research and the dentist perspective.
What Does the Research Actually Show?
A growing body of small-scale studies suggests oil pulling may reduce certain oral bacteria, plaque levels, and markers of gingivitis, though researchers and dental organizations emphasize that the evidence remains preliminary and limited in scope.
Oil Pulling and Plaque: Is There a Real Effect?
Several randomized controlled trials have compared oil pulling, particularly with sesame or coconut oil, against chlorhexidine mouthwash, which is considered a gold standard antimicrobial rinse in dentistry. Some of these studies have found that oil pulling performed comparably to chlorhexidine in reducing plaque index scores and bacterial counts, including Streptococcus mutans, one of the primary bacteria associated with tooth decay.
A 2016 study published in the Journal of Traditional and Complementary Medicine found that coconut oil pulling significantly reduced plaque scores and signs of gingivitis in adolescent participants after 30 days, with results comparable to chlorhexidine mouthwash. According to the researchers, the antimicrobial activity was attributed in part to the saponification and emulsification process that occurs when oil interacts with saliva.
You can explore peer-reviewed research on oil pulling and oral health through PubMed, the NIH’s database of biomedical literature, where multiple indexed studies are available. It is important to note that many of these studies are small, conducted over short timeframes, and lack the rigorous methodology needed to draw sweeping conclusions.
Does Oil Pulling Work for Bad Breath?
Halitosis, or persistent bad breath, is often caused by volatile sulfur compounds produced by anaerobic bacteria living in the mouth. Some studies suggest that oil pulling may reduce these bacterial populations and, as a result, may help reduce bad breath for some people. However, the evidence is similarly preliminary, and bad breath can have many underlying causes, including dry mouth, gum disease, and systemic health conditions, that oil pulling would not address.
Oil Pulling and Gum Health
Gingivitis, the early stage of gum disease, is marked by inflammation, redness, and bleeding of the gums. Research suggests that the mechanical swishing action of oil pulling, combined with any antimicrobial properties of the oil, may reduce gingival inflammation over time in some study participants. According to the National Institute of Dental and Craniofacial Research, part of the NIH, maintaining good oral hygiene is the foundation of gum disease prevention, with brushing twice daily and flossing daily remaining the primary recommended practices.
What Dentists and Dental Organizations Say
Most dental professionals and organizations, including the American Dental Association, do not endorse oil pulling as a proven dental treatment and caution against using it as a substitute for evidence-based oral hygiene practices.
The American Dental Association’s Position
According to the American Dental Association (ADA), there is not enough reliable scientific evidence to recommend oil pulling as a dental health practice, and the organization has not included it in its clinical guidelines. The ADA continues to recommend brushing with fluoride toothpaste twice daily, flossing once daily, limiting sugary foods and drinks, and visiting a dentist regularly as the foundation of good oral health.
Is It Safe to Try?
For most healthy adults, oil pulling with food-grade coconut, sesame, or sunflower oil is generally considered low-risk when practiced correctly. The critical safety points dentists consistently raise include the following. You should always spit the oil into a trash can rather than the sink, since it can solidify and clog pipes. You should never swallow the used oil, as it will contain the bacteria and debris it has collected. And oil pulling should never replace brushing, flossing, or professional dental care.
According to Mayo Clinic, oil pulling is unlikely to cause harm when practiced correctly, but there is limited evidence it provides significant oral health benefits beyond what proper brushing and flossing already achieve. Mayo Clinic also notes that swallowing the oil could potentially introduce harmful bacteria into the digestive system.

Oil Pulling Side Effects: What to Watch For
Reported oil pulling side effects are generally mild, but some individuals experience jaw soreness, nausea, or lipoid pneumonia if the oil is accidentally inhaled, making proper technique important.
Commonly Reported Issues
Because the practice involves vigorous swishing for up to 20 minutes, jaw fatigue and soreness are among the most frequently reported complaints, particularly for newcomers. Some people also experience nausea from the texture or taste of the oil, especially first thing in the morning. Starting with 5 minutes and gradually working up to longer sessions may help with this.
A more serious, though rare, concern is lipoid pneumonia, a lung condition that can result from accidentally inhaling oil droplets into the lungs. This risk is considered low for careful practitioners but is a reason why children, elderly individuals, or those with swallowing difficulties should approach the practice cautiously or avoid it entirely.
Who Should Avoid Oil Pulling?
People with certain nut or seed allergies should carefully check the composition of any oil they use. Those with conditions affecting swallowing, or young children who may be at higher risk of aspiration, should consult a dentist or physician before attempting oil pulling. As with any health practice, consulting a dental or medical professional before starting is a reasonable first step, particularly for those with existing oral health conditions.
Comparing Oil Pulling to Standard Oral Hygiene
When compared directly to brushing, flossing, and fluoride use, oil pulling does not have the same volume or quality of research support, though some studies suggest it may offer a useful supplementary benefit.
| Practice | Evidence Level | ADA Recommended? | Plaque Reduction | Bacteria Reduction | Gum Health Benefit |
|---|---|---|---|---|---|
| Brushing with fluoride toothpaste (twice daily) | Strong, extensive RCTs | Yes | High | High | Significant |
| Flossing (once daily) | Moderate to strong | Yes | Moderate (interproximal) | Moderate | Significant for gum line |
| Chlorhexidine mouthwash | Strong clinical evidence | Prescription use | High | Very high | Significant |
| Oil pulling (coconut oil) | Preliminary, small studies | No | Moderate (some studies) | Moderate (some studies) | Modest in some trials |
| Antimicrobial mouthwash (OTC) | Moderate evidence | Yes (some formulations) | Moderate | Moderate to high | Moderate |
| Water flossers / Oral irrigators | Moderate clinical evidence | Yes (supplementary) | Moderate | Moderate | Beneficial for gum pockets |
How to Try Oil Pulling: A Practical Overview
If you choose to try oil pulling, most guidance suggests using one tablespoon of food-grade coconut or sesame oil, swishing gently for 10 to 20 minutes in the morning before eating or brushing, and spitting into a trash can.
Practitioners typically recommend doing oil pulling first thing in the morning on an empty stomach, before drinking water or coffee. The key word is “gentle” swishing rather than aggressive gargling, since the latter can cause jaw fatigue and increase aspiration risk. After spitting out the oil, rinsing with warm water and then proceeding with your normal brushing and flossing routine is the standard approach.
Finding an uninterrupted 20-minute window every morning can be challenging. To make the practice sustainable without rushing, many practitioners multi-task by oil pulling while showering, preparing breakfast, or checking their morning emails—ensuring it acts as a seamless prelude to, rather than a disruption of, their essential brushing and flossing routine.
Alternative Perspectives
Not everyone in the dental and research communities agrees on how to interpret the existing oil pulling data. Some researchers and integrative health practitioners argue that even if oil pulling’s benefits are modest compared to conventional methods, it represents a low-cost, low-risk complement that may benefit patients who struggle with consistent flossing or have sensitivities to conventional mouthwash ingredients. From this perspective, an imperfect practice that someone actually does consistently may be more valuable than a clinically superior one they skip.
On the other hand, mainstream dental organizations express concern that promoting oil pulling without strong evidence risks giving people a false sense of security about their oral health, potentially leading them to deprioritize proven practices like fluoride use and professional cleanings. There is also a valid argument that the existing studies are too small, too short, and too methodologically varied to draw meaningful clinical conclusions, and that the practice warrants more rigorous, large-scale investigation before any broader recommendations can be made. Both perspectives are reasonable and reflect genuine uncertainty in the current evidence base.

Frequently Asked Questions About Oil Pulling
There is currently no strong scientific evidence that oil pulling whiten teeth in the way that peroxide-based whitening products do. Some users report that surface stains appear reduced after consistent practice, possibly due to the mechanical action of swishing removing superficial debris, but no peer-reviewed clinical trials confirm a true whitening effect. For verified teeth whitening options, speaking with a dentist about evidence-based treatments is the most reliable path.
The small studies that have examined oil pulling generally ran for 30 days or longer before measuring outcomes like plaque reduction and gum inflammation. Results vary significantly between individuals, and there is no established clinical timeline. Anyone expecting fast or dramatic results may be disappointed, as the existing research suggests any benefits are gradual and modest.
No. Dental professionals and organizations including the American Dental Association consistently emphasize that oil pulling should not replace brushing with fluoride toothpaste or flossing. These two practices have the strongest evidence base for preventing tooth decay and gum disease, and no alternative practice currently has the research support needed to substitute for them. Oil pulling, if used at all, is best considered a supplementary habit.
Coconut oil is the most commonly studied oil in recent research, partly due to its lauric acid content, which has shown antimicrobial properties in laboratory settings. Sesame oil has the longest historical use in Ayurvedic practice and has also been studied in clinical trials. Sunflower oil is another option used in some research. There is no definitive evidence that one oil produces significantly better outcomes than another, and individual preference may be as important a factor as composition.
