No, oil pulling cannot reverse cavities once they’ve formed. While this ancient Ayurvedic practice offers several oral health benefits, scientific evidence does not support its ability to regenerate tooth structure damaged by decay. Oil pulling may help reduce cavity-causing bacteria and complement your oral hygiene routine, but established cavities require professional dental treatment. This article examines the scientific evidence behind oil pulling and its proper role in dental care.
What Is Oil Pulling?
Oil pulling involves swishing oil in your mouth for 15-20 minutes to remove bacteria.
Oil pulling is a traditional Ayurvedic practice that originated in India thousands of years ago. It involves swishing oil around your mouth for approximately 15-20 minutes before spitting it out. Traditionally, sesame or sunflower oil was used, though coconut oil has become increasingly popular in modern practice due to its pleasant taste and antimicrobial properties.
The practice works by “pulling” bacteria from the mouth as you swish. Since bacteria in dental plaque are surrounded by a lipid (fat) membrane, they naturally adhere to the oil during the swishing process. The mechanical action of swishing also helps dislodge food particles and debris from between teeth and along the gumline.
Proponents claim oil pulling offers numerous benefits, including reducing bad breath, whitening teeth, decreasing sensitivity, improving gum health, and even reversing cavities. However, scientific evidence supports some of these claims more strongly than others.
How Cavities Form
To understand why oil pulling cannot reverse cavities, it’s important to understand how cavities develop. Tooth decay occurs through a process of demineralization caused by acids produced by bacteria in dental plaque.
The cavity formation process typically follows these stages:
- Bacteria in plaque feed on sugars and carbohydrates from your diet
- As bacteria metabolize these sugars, they produce acids
- These acids dissolve minerals (primarily calcium and phosphate) from tooth enamel
- This demineralization weakens the enamel structure
- Over time, the weakened area collapses, forming a cavity or hole
- If untreated, decay progresses deeper into the tooth, affecting dentin and potentially the pulp
In very early stages of demineralization, before a cavity forms, the process can potentially be reversed through remineralization. However, once a true cavity (physical hole) has formed in the tooth structure, remineralization cannot rebuild the lost tooth structure.
Scientific Evidence on Oil Pulling and Cavities
Multiple scientific studies have examined oil pulling’s effects on oral health, with mixed results regarding its effectiveness for various conditions. Let’s examine what the research tells us specifically about oil pulling and cavities.
Study 1: Antibacterial Effects on Cavity-Causing Bacteria
A 2016 study published in the Journal of Contemporary Dental Practice examined coconut oil pulling’s effect on Streptococcus mutans, the primary bacteria responsible for tooth decay. The study found that oil pulling significantly reduced S. mutans counts in saliva after just two weeks of daily practice. Researchers concluded that coconut oil pulling could be an effective preventive measure against tooth decay when used alongside conventional oral hygiene practices.
However, while reducing bacteria may help prevent new cavities from forming, this study did not demonstrate any reversal of existing cavities.
Study 2: Comparison with Chlorhexidine Mouthwash
Another study published in the Journal of Clinical and Diagnostic Research compared coconut oil pulling with chlorhexidine mouthwash (a gold standard antimicrobial rinse in dentistry). The researchers found that while both methods reduced S. mutans counts, neither treatment showed any ability to remineralize or repair existing cavities.
The study concluded that oil pulling could be a cost-effective preventive measure but should not replace professional treatment for existing decay.
Study 3: Plaque Reduction and Gingivitis
A 2020 study in the European Journal of Dentistry found that virgin coconut oil was effective at reducing plaque accumulation when used in oil pulling. While this suggests potential benefits for preventing new cavities, the researchers explicitly noted that oil pulling cannot reverse existing cavities and should be considered a complementary practice to standard oral hygiene.
Scientific Consensus: Current research indicates that while oil pulling may help reduce cavity-causing bacteria and prevent new cavities from forming, there is no scientific evidence that it can reverse or repair existing cavities.
Oil Pulling vs. Modern Dental Treatments
Oil Pulling
- May reduce cavity-causing bacteria
- Can help prevent plaque buildup
- Potentially improves gum health
- Cannot remineralize damaged tooth structure
- Does not repair existing cavities
- Limited scientific evidence for cavity prevention
Modern Dental Treatments
- Dental fillings physically repair cavity damage
- Fluoride treatments remineralize early decay
- Professional cleanings remove hardened plaque
- Sealants provide physical barrier against bacteria
- Extensive scientific evidence supporting effectiveness
- Addresses both prevention and treatment
“While oil pulling may have some benefits for oral hygiene, it cannot reverse established cavities. Once a cavity has formed, the lost tooth structure cannot be regenerated naturally and requires professional dental treatment.” — Dr. Christine Frank, DDS, American Dental Association.
Limitations of Oil Pulling
While oil pulling offers certain benefits for oral health, it’s important to understand its limitations, particularly regarding cavity treatment:
Benefits of Oil Pulling
- Reduces harmful bacteria in the mouth
- May help prevent plaque formation
- Can improve gum health and reduce gingivitis
- May freshen breath by removing bacteria
- Natural and cost-effective practice
Limitations of Oil Pulling
- Cannot reverse existing cavities
- Does not rebuild damaged tooth structure
- Not a substitute for professional dental care
- Time-consuming (15-20 minutes daily)
- Limited scientific evidence compared to conventional treatments
The American Dental Association (ADA) does not recommend oil pulling as a dental hygiene practice due to insufficient scientific evidence. The ADA states that “scientific studies have not provided the necessary clinical evidence to demonstrate that oil pulling reduces the incidence of dental caries [cavities], whitens teeth, or improves oral health and well-being.”
Need Professional Cavity Treatment?
If you’re experiencing tooth pain or suspect you have cavities, professional dental care is essential. Oil pulling cannot reverse existing decay.
How to Properly Practice Oil Pulling
If you’d like to incorporate oil pulling into your oral hygiene routine as a complementary practice, here’s how to do it properly:
- Choose your oil: Coconut oil is most commonly recommended due to its pleasant taste and antimicrobial properties, but sesame oil or sunflower oil can also be used.
- Measure the right amount: Use approximately 1 tablespoon of oil. Starting with a smaller amount may be easier for beginners.
- Swish properly: Gently swish the oil around your mouth, pulling it between your teeth for 15-20 minutes. Avoid gargling or swallowing the oil.
- Spit carefully: After swishing, spit the oil into a trash can, not the sink, as it can solidify and clog pipes.
- Rinse thoroughly: Rinse your mouth with warm water or salt water to remove any remaining oil residue.
- Brush and floss: Follow up with your regular oral hygiene routine, including brushing and flossing.
Best Time for Oil Pulling: Many practitioners recommend oil pulling in the morning on an empty stomach before eating or drinking anything. However, consistency is more important than timing.
Important: If you experience jaw fatigue, nausea, or discomfort during oil pulling, reduce the amount of oil or the duration. Stop immediately if you experience any adverse reactions.
Oil Pulling: Myths vs. Facts
| Myth | Fact |
| Oil pulling can reverse cavities | Oil pulling cannot rebuild damaged tooth structure or reverse existing cavities. Once a cavity forms, professional dental treatment is necessary. |
| Oil pulling replaces brushing and flossing | Oil pulling should complement, not replace, regular brushing and flossing. It’s an additional practice, not a substitute for standard oral hygiene. |
| Oil pulling detoxifies the body | There is no scientific evidence that oil pulling removes toxins from the bloodstream or body. Its benefits are limited to the oral cavity. |
| Oil pulling whitens teeth dramatically | While oil pulling may help remove surface stains by reducing plaque, it does not change the natural color of teeth or provide significant whitening effects. |
| Any oil works equally well | Coconut oil contains lauric acid with antimicrobial properties, potentially making it more effective than other oils for oral bacteria reduction. |
When to See a Dentist
While oil pulling may offer some benefits as a complementary practice, it’s crucial to know when professional dental care is necessary. Here are signs that indicate you should see a dentist rather than relying solely on oil pulling:
- Tooth pain or sensitivity – Persistent pain or sensitivity to hot, cold, or sweet foods may indicate a cavity
- Visible holes or pits – Any visible damage to tooth structure requires professional evaluation
- Dark spots on teeth – Discoloration may indicate decay that needs treatment
- Bleeding or swollen gums – These symptoms may indicate gingivitis or more serious gum disease
- Bad breath that persists – Chronic bad breath can signal underlying dental issues
- Loose teeth – Adult teeth should not be loose; this requires immediate attention
- Regular check-ups – Even without symptoms, visit a dentist every 6 months for preventive care
“Early intervention is key to treating cavities effectively. The longer a cavity is left untreated, the more extensive and expensive the treatment becomes. No amount of oil pulling can substitute for proper dental care once decay has begun.”
— American Dental Association

A Balanced Approach to Oral Health
The most effective approach to oral health combines traditional dental care with complementary practices like oil pulling. Here’s how to create a balanced oral hygiene routine:
Daily Essentials
- Brush twice daily with fluoride toothpaste
- Floss at least once daily
- Use antimicrobial mouthwash
- Clean your tongue
Complementary Practices
- Oil pulling (15-20 minutes daily)
- Xylitol gum or mints after meals
- Calcium-rich foods for tooth strength
- Adequate hydration for saliva production
Professional Care
- Regular dental check-ups (every 6 months)
- Professional cleanings
- Prompt treatment of cavities
- Preventive treatments like sealants
By combining these approaches, you can maximize the benefits of both traditional and complementary practices. Oil pulling can be a valuable addition to your routine, but it should never replace professional dental care, especially for treating existing cavities.
Frequently Asked Questions
Can oil pulling heal a small cavity?
No, oil pulling cannot heal or reverse a cavity once it has formed. While oil pulling may help reduce bacteria that cause cavities, it cannot rebuild tooth structure that has been damaged by decay. Even small cavities require professional dental treatment, typically a filling, to prevent further decay.
Which oil is best for preventing cavities?
Coconut oil is often considered the most effective oil for oil pulling due to its high lauric acid content, which has antimicrobial properties. Studies suggest it may be more effective at reducing Streptococcus mutans, the primary bacteria responsible for cavities. However, sesame oil and sunflower oil are also traditional options that may provide benefits.
How long does it take to see results from oil pulling?
Studies show that consistent oil pulling may produce noticeable reductions in harmful bacteria after about two weeks of daily practice. However, results vary by individual, and oil pulling should be viewed as a long-term complementary practice rather than a quick fix. Remember that while you may see improvements in gum health or breath freshness, oil pulling will not reverse existing cavities.
Is oil pulling safe for everyone?
Oil pulling is generally considered safe for most adults, but it may not be appropriate for everyone. Children under 5 should not practice oil pulling due to the risk of swallowing the oil or choking. People with allergies to coconut, sesame, or sunflower should avoid using those oils. If you experience jaw pain, nausea, or other discomfort during oil pulling, you should stop and consult a healthcare provider.
Should I oil pull before or after brushing?
Most practitioners recommend oil pulling first thing in the morning, before brushing your teeth and on an empty stomach. After oil pulling, rinse your mouth thoroughly with water, then brush and floss as normal. This sequence allows the oil to remove bacteria before brushing removes any remaining residue.
Why don’t dentists recommend oil pulling?
Many dentists don’t actively recommend oil pulling because there is limited scientific evidence supporting its effectiveness compared to established dental practices. The American Dental Association does not currently recommend oil pulling due to insufficient clinical evidence. However, some dentists acknowledge that oil pulling may offer benefits as a complementary practice alongside traditional oral hygiene methods, just not as a replacement for proven treatments or for reversing cavities.
Conclusion
Oil pulling is an ancient practice that may offer certain benefits for oral health, including reducing harmful bacteria, improving gum health, and freshening breath. However, scientific evidence clearly shows that oil pulling cannot reverse cavities once they’ve formed. The physical damage to tooth structure caused by decay requires professional dental treatment.
If you’re interested in oil pulling, consider it a complementary practice to add to your oral hygiene routine—not a replacement for brushing, flossing, and regular dental visits. For existing cavities, consult with a dental professional promptly to prevent further decay and protect your long-term oral health.
Remember that the best approach to cavity management combines prevention through good oral hygiene, a balanced diet low in sugars, and regular professional dental care. Oil pulling may have a place in this comprehensive approach, but its role is supportive rather than curative for established cavities.
