Whiter teeth naturally?
The idea sounds perfect – swish some coconut oil around your mouth and get a brighter smile without expensive treatments. Thousands of people share their success stories online, showing off what they claim are coconut oil-whitened smiles.
Many wonder: “Can a natural product really replace commercial whiteners?”
The scientific verdict: is there proof?
Direct whitening effects
The short answer: No solid scientific evidence shows coconut oil chemically whitens teeth.
Teeth whitening typically works through oxidation – chemical reactions that break down stain molecules on or within the tooth. Hydrogen peroxide and carbamide peroxide are proven whitening agents that work this way.
Coconut oil simply doesn’t contain these compounds. Its molecular structure can’t penetrate tooth enamel or break down stain molecules the way proven whiteners do.
Coconut oil composition analysis
| Component | Percentage | Potential oral health effect |
|---|---|---|
| Lauric Acid | 49% | Antimicrobial properties against some oral bacteria |
| Myristic Acid | 18% | Limited antimicrobial effect |
| Palmitic Acid | 8% | Minimal known oral health benefits |
| Caprylic Acid | 8% | Some antimicrobial properties |
| Capric Acid | 7% | Some antimicrobial properties |
| Other components | 10% | Varies |
None of these components contain peroxides or other compounds known to oxidize or bleach stains.
Indirect “brightening” – the plaque factor
Coconut oil does contain lauric acid, which studies show has antibacterial properties. Research in the Journal of Contemporary Dental Practice (Peedikayil et al., 2015) found oil pulling reduced Streptococcus mutans, a bacteria linked to tooth decay.
By reducing plaque (that sticky film that builds up on teeth), your teeth might look cleaner and therefore brighter – but this isn’t the same as changing your tooth color.
What “oil pulling” is and its historical context
Oil pulling comes from Ayurvedic medicine, practiced for thousands of years in India. The traditional practice involves swishing oil in your mouth for oral health benefits, not just teeth whitening.
In Ayurveda, oil pulling aims to remove toxins and improve overall oral hygiene – whitening was never the primary goal.
Types of oils used traditionally
- Coconut oil: Most popular today due to pleasant taste and antimicrobial properties
- Sesame oil: Traditional choice in Ayurvedic practice
- Sunflower oil: Sometimes used as an alternative
Understanding tooth discoloration: why do teeth stain?
Extrinsic stains
These are surface stains on the outside of your teeth from:
- Coffee and tea
- Red wine
- Tobacco
- Berries
- Plaque buildup
Potential role of coconut oil: It might help remove some fresh surface stains by reducing plaque, but the effect is minimal compared to brushing with a whitening toothpaste.
Intrinsic stains
These stains occur within the tooth structure and result from:
- Trauma to the tooth
- Certain medications (like tetracycline)
- Fluorosis (too much fluoride during tooth development)
- Natural aging
Why coconut oil won’t work: These stains are embedded in the tooth structure. Coconut oil can’t penetrate deep enough to affect these stains.
Age-related discoloration
As we age, our enamel naturally thins, making the yellowish dentin layer underneath more visible. This isn’t staining – it’s structural change that only professional treatments can address.
Types of tooth stains and effectiveness of coconut oil
| Type of stain | Causes | Can coconut oil help? | Better alternatives |
|---|---|---|---|
| Fresh surface stains | Coffee, tea, red wine, berries | Minimal effect – may help with very recent stains | Whitening toothpaste, regular brushing |
| Set surface stains | Long-term exposure to staining foods/drinks | Very limited – cannot penetrate or break down set stains | Whitening strips, professional cleaning |
| Plaque-related discoloration | Bacterial buildup | Potential moderate effect through plaque reduction | Regular brushing, flossing, dental cleaning |
| Intrinsic stains | Medications, trauma, fluorosis | No effect – cannot penetrate enamel | Professional whitening, veneers |
| Age-related yellowing | Natural thinning of enamel | No effect – structural change | Professional whitening, veneers |
Coconut oil for oral health: beyond whitening claims
Potential benefits (backed by some evidence)
Reducing plaque and gingivitis
Research in the Journal of Indian Society of Periodontology found oil pulling reduced plaque and gingivitis when used regularly. A 2015 study showed similar benefits to chlorhexidine mouthwash for reducing gum inflammation.
Combating bad breath
By reducing bacteria that cause bad breath, coconut oil might freshen your mouth. A small study in the Journal of Clinical and Diagnostic Research supports this benefit.
Moisturizing the mouth
Many users report relief from dry mouth symptoms, though this benefit remains mostly anecdotal.
Scientific research on coconut oil for oral health
| Study | Year | Sample size | Duration | Key findings | Limitations |
|---|---|---|---|---|---|
| Peedikayil et al. | 2015 | 60 adolescents | 30 days | Significant plaque reduction comparable to chlorhexidine | Small sample, no direct whitening measurement |
| Shanbhag et al. | 2017 | 40 participants | 21 days | Reduced S. mutans counts and gingivitis | No measurement of tooth shade change |
| Nagilla et al. | 2018 | 45 participants | 14 days | Reduced halitosis and plaque scores | Self-reported outcomes, no control group |
| Jauhari et al. | 2020 | 75 children | 30 days | Decreased plaque and improved gingival health | No whitening assessment included |
How to do oil pulling (if you choose to try)
- Put 1-2 tablespoons of coconut oil in your mouth (preferably organic, cold-pressed)
- Swish it around for 15-20 minutes (start with 5 minutes if this is too long)
- Don’t gargle or swallow – the oil collects bacteria
- Spit the oil into the trash (not down drains as it can clog pipes)
- Rinse your mouth thoroughly with warm water
- Brush your teeth normally afterward
Troubleshooting common oil pulling issues
- Gag reflex activates: Start with just 1 teaspoon and gradually increase
- Can’t manage 15-20 minutes: Begin with 5 minutes and work up
- Oil becomes too thick: You’re doing it right! The oil mixes with saliva and becomes milky and thin at first, then thicker as it mixes with plaque
- Jaw soreness: Swish more gently or reduce duration
- Unpleasant taste: Try a different oil or add a drop of peppermint essential oil (if approved by your dentist)
Important considerations and potential downsides
- Not a replacement for brushing, flossing, or dental visits
- Possible upset stomach if accidentally swallowed
- Jaw soreness from extended swishing
- Rare cases of lipoid pneumonia if oil is aspirated into lungs
- Not suitable for people with coconut allergies
- Time-consuming (15-20 minutes daily)
Effective & proven ways to whiten your teeth
Whitening methods comparison
| Method | Effectiveness | Cost | Time investment | Potential side effects | Best for |
|---|---|---|---|---|---|
| Coconut oil pulling | ★☆☆☆☆ (minimal whitening) | $5-15 per jar | 15-20 min daily for weeks | Rare: jaw soreness, lipoid pneumonia if aspirated | Supplement to regular oral hygiene, plaque reduction |
| Professional whitening | ★★★★★ (3-8 shades lighter) | $300-800 | 1-2 hours (single visit) | Temporary sensitivity, gum irritation | Quick, dramatic results |
| At-home whitening trays | ★★★★☆ (2-5 shades lighter) | $100-400 | 30-60 min daily for 1-2 weeks | Sensitivity, gum irritation if ill-fitting | Controlled, gradual whitening |
| Whitening strips | ★★★☆☆ (1-2 shades lighter) | $20-50 | 30 min daily for 1-2 weeks | Sensitivity, uneven results | Budget-friendly surface stain removal |
| Whitening toothpaste | ★★☆☆☆ (surface stains only) | $5-10 | 2 min, twice daily | Potential enamel wear with abrasive formulas | Daily maintenance |
| Baking soda | ★★☆☆☆ (surface stains only) | $2-5 | 2 min, 1-2 times weekly | Enamel abrasion with overuse | Occasional brightening |
Professional teeth whitening
In-office treatments use high-concentration peroxide gels (25-40%) activated by special lights or lasers. These treatments can lighten teeth by several shades in just one visit, though they typically cost $300-800.
Dentist-prescribed at-home kits use custom trays with professional-grade whitening gel (10-22% carbamide peroxide). These provide gradual results over 1-2 weeks.
What makes professional whitening effective:
- Higher concentration of active ingredients
- Custom-fitted trays that keep the whitening agent in place
- Professional supervision reduces risks
- Special light activation in some treatments
Over-the-counter (OTC) whitening products
Whitening toothpastes
These work through mild abrasives and sometimes low concentrations of peroxide (usually 1-1.5%). They remove surface stains but can’t change intrinsic tooth color.
Whitening strips and gels
These contain hydrogen peroxide (5-10%) or carbamide peroxide (10-20%) that penetrates enamel to break down stain molecules. Studies show they can lighten teeth 1-2 shades with consistent use over 7-14 days.
Potential issues: Tooth sensitivity and gum irritation are common side effects, affecting 10-30% of users according to dental studies.
Other home remedies (use with caution)
Baking soda
Can help remove surface stains through mild abrasive action. Too abrasive for daily use – can damage enamel if used too frequently. The American Dental Association suggests limiting use to once or twice weekly.
Hydrogen peroxide rinses
Diluted solutions (1-3%) may help brighten teeth. Always consult your dentist first, as improper use can damage gums. Never use household hydrogen peroxide at full strength (typically 3-6%).
Unlike coconut oil, these remedies contain compounds that can actually break down stain molecules.
The importance of prevention
- Brush twice daily with fluoride toothpaste
- Floss daily to remove plaque between teeth
- Limit staining foods and drinks (coffee, tea, red wine)
- Rinse with water after consuming staining substances
- Use a straw when drinking staining beverages
- Quit smoking and tobacco use
- Get regular dental cleanings twice yearly
Coconut oil for teeth: fact vs. fiction – a quick summary
Myth: Coconut oil is a powerful tooth whitener.
Fact: No strong scientific evidence supports intrinsic whitening; it may help remove some surface plaque, giving a cleaner appearance.
Myth: Coconut oil can replace your toothpaste or dental visits.
Fact: It should not replace brushing, flossing, or professional dental care.
Myth: Oil pulling detoxifies your entire body through your mouth.
Fact: This claim lacks scientific support; benefits are limited to potentially reducing certain oral bacteria.
Myth: You’ll see dramatic whitening results within days.
Fact: Even with dedicated oil pulling, any minor brightening takes weeks of consistent use, and results are minimal compared to proven methods.
Myth: All coconut oils work equally well for teeth.
Fact: If trying oil pulling, organic virgin (unrefined) coconut oil is preferable as it contains more of the beneficial compounds.
Potential truth:
Coconut oil may contribute to better gum health and reduced plaque when used correctly as a supplementary practice.
Expert perspectives on coconut oil for teeth
While many online sources promote coconut oil pulling for whiter teeth, professional dental organizations have more measured views:
American Dental Association (ADA): The ADA states, “scientific studies have not proven that oil pulling reduces cavities, whitens teeth or improves oral health and well-being.” They recommend proven practices like brushing with fluoride toothpaste and regular flossing instead.
Dr. Mark Burhenne, DDS (founder of AsktheDentist.com): “Oil pulling may help reduce plaque and improve gum health, but don’t expect it to whiten teeth significantly. The whitening products we use professionally contain peroxides that actually change the color of the teeth, which oil simply cannot do.”
Dr. Suhail Mohiuddin, DMD (holistic dentist): “I recommend oil pulling to some patients as a supplementary practice for gum health, but I’m always clear that it won’t replace thorough brushing and flossing, nor will it whiten teeth the way professional treatments can.”
Combining coconut oil with other natural remedies
Some people combine coconut oil with other ingredients in hopes of enhancing whitening effects. Here’s what science says about these combinations:
Coconut oil + baking soda
Potential benefit: Baking soda’s mild abrasiveness may help remove surface stains while coconut oil might help reduce plaque. Caution: Too abrasive for daily use and still won’t produce significant whitening.
Coconut oil + turmeric
Potential benefit: Some studies show turmeric has anti-inflammatory properties for gum health. Reality check: Despite claims, turmeric is unlikely to whiten teeth and may temporarily stain them yellow.
Coconut oil + essential oils
Potential benefit: Peppermint or tea tree oil may add antimicrobial properties. Caution: Essential oils must be food-grade and used in tiny amounts; many aren’t safe for oral use.
The bottom line: what science really says
After reviewing all available scientific literature, here’s the reality about coconut oil and teeth whitening:
- Limited evidence for direct whitening: No peer-reviewed studies demonstrate that coconut oil chemically whitens teeth.
- Some evidence for plaque reduction: Several small studies show coconut oil pulling may reduce plaque buildup similar to chlorhexidine mouthwash when used consistently.
- Minimal brightening effect: Any brightening effect comes from removing plaque, not from changing tooth color.
- Better alternatives exist: For actual whitening, dental-grade peroxide-based products have substantial scientific backing.
- Safe as a supplement: When used correctly as an addition to regular oral hygiene, coconut oil pulling has minimal risks.
If you’re looking for truly whiter teeth, schedule a consultation with your dentist to discuss professional options tailored to your specific needs.

FAQs
Does coconut oil pulling actually whiten teeth?
Coconut oil pulling may help teeth appear slightly brighter by reducing plaque, but it doesn’t chemically whiten teeth the way peroxide products do. Any whitening effect is minimal and indirect.
How long does it take for coconut oil to whiten teeth?
If you see any brightening effect from reducing plaque, it typically takes 2-4 weeks of daily oil pulling for 15-20 minutes. However, don’t expect dramatic whitening results as coconut oil doesn’t contain bleaching agents.
How soon will I see results from oil pulling?
For plaque reduction and gum health benefits, some studies show improvements within 1-2 weeks of daily use. For any minor brightening effect, expect at least 3-4 weeks of consistent practice.
Can yellow teeth become white again with coconut oil?
Yellow teeth due to deep staining or natural dentin color cannot be made significantly whiter with coconut oil. Professional whitening or dental veneers are the most effective options for yellow teeth.
Is it okay to brush teeth with coconut oil?
While not harmful, brushing with coconut oil alone isn’t effective. Coconut oil lacks fluoride and abrasives needed to clean teeth properly. If you want to use coconut oil, do it as a supplement to regular brushing with fluoride toothpaste.
What happens if I brush my teeth with coconut oil every day?
Brushing with coconut oil alone may lead to increased plaque buildup and potential cavity development since it doesn’t remove plaque effectively. Using it alongside (not instead of) regular toothpaste is safer.
How long can you leave coconut oil on your teeth?
For oil pulling, 15-20 minutes is standard. Leaving oil on teeth longer doesn’t provide additional benefits and may cause jaw discomfort.
Do dentists recommend coconut oil pulling?
Many dentists acknowledge potential benefits for reducing plaque and gingivitis but don’t recommend it as a whitening method. The American Dental Association doesn’t currently recommend oil pulling due to insufficient scientific evidence.
How do I make my teeth white faster?
For faster whitening results, professional dental whitening is most effective, providing noticeable results in a single visit. At-home whitening strips with peroxide also work much faster than any natural remedy.
Can coconut oil remove plaque from teeth?
Studies show coconut oil pulling may help reduce plaque when done consistently for 15-20 minutes daily, but it’s less effective than brushing and flossing.
