Oil Pulling with Olive Oil | Application, Current State of Research 2026, and Limitations
A spoonful of olive oil.
Swish it around in your mouth for several minutes.
Spit it out.
And use this to care for your teeth, gums, and oral cavity?
So-called oil pulling sounds surprisingly simple at first.
On social media, however, it quickly becomes much more than that.
Oil pulling is said to:
- Whiten teeth
- Remove plaque
- Treat gum inflammation
- Prevent cavities
- Pull bacteria out of the mouth
- Detoxify the body
- And even have effects far beyond the oral cavity
This is exactly where I would like to be cautious.
Oil pulling has a long tradition.
There is now clinical research on it as well.
But:
Tradition is not automatically proof of effectiveness.
And:
An interesting study result is not yet a dental recommendation.
That is why I want to structure this Green Agora article differently.
Not:
Why oil pulling with olive oil works.
But:
What do we really know about oil pulling with olive oil?
Where does the tradition come from?
What has been investigated?
How robust are the studies?
Does high-quality extra virgin olive oil have a proven advantage?
What role do polyphenols play?
And what should one know before integrating oil pulling into a personal morning routine?

Oil Pulling with Olive Oil | The Most Important Answers First
| What is oil pulling? | A traditional method in which edible oil is swished in the mouth for several minutes and then spit out. |
| Is oil pulling scientifically proven? | There are clinical studies with potential short-term effects on individual parameters. However, the most important meta-analysis rates the overall evidence as very low certainty. |
| Does oil pulling replace brushing? | No. Brushing with fluoride toothpaste and appropriate interdental cleaning remain the foundation. |
| Is olive oil better than coconut or sesame oil? | There is currently no robust evidence for this. |
| Do I need a high-phenolic olive oil? | No. There is no robust evidence that a particularly high polyphenol or oleocanthal level makes oil pulling more effective. |
| Does oil pulling remove toxins? | There is no robust clinical evidence for a detoxifying effect on the body. |
| Can oil pulling have risks? | The oil is spit out after pulling. It is crucial to avoid aspiration into the airways. Rare cases of lipoid pneumonia have been described. |
| Must oil pulling be done on an empty stomach in the morning? | There is no robust scientific evidence for a specific advantage to doing it in the morning or on an empty stomach. |
Where does oil pulling come from?
Oil pulling is usually associated with traditional Indian or Ayurvedic medicine.
In historical descriptions, the terms that appear in particular are:
Kavala
and:
Gandusha.
The two traditional procedures are not completely identical.
In Gandusha, the mouth is filled with a larger amount of liquid so that active movement is only possible to a limited extent.
In Kavala, a smaller amount is used that can be moved around in the mouth.
The widespread practice in the West today:
Oil pulling
therefore resembles more of a modern interpretation of the Kavala principle.
Traditionally, plant oils were used, such as:
- Sesame oil
- Sunflower oil
- Later also coconut oil
Olive oil is now also one of the oils used for this purpose.
Historical use and modern scientific evaluation should nevertheless be considered separately.
What does oil pulling mean in practice?
In modern oil pulling, a small amount of edible oil is taken into the mouth.
The oil is then:
moved between the teeth,
across the tongue,
along the gums,
and through the entire oral cavity.
Afterward, it is spit out.
In studies and traditional descriptions, the following vary significantly:
- Amount of oil
- Duration
- Time of day
- Oil used
- Frequency
You find applications ranging from approximately:
5 to 20 minutes.
This is precisely why there is no scientifically established standard:
10 ml for exactly 17 minutes is optimal.
Such a recommendation would not be evidence-based.
Must oil pulling be done in the morning?
No.
Morning use is part of many traditional and modern routines.
However, no scientifically proven special advantage for this time of day can be derived from this.
There is also no convincing clinical evidence for the common recommendation:
strictly on an empty stomach.
If someone finds oil pulling pleasant in the morning, a personal routine can be built around it.
However, the time of day should not be used as a medical promise of efficacy.
What does current research say about oil pulling?
The scientific answer is now more interesting than a simple:
works
or:
does not work.
A systematic review with a meta-analysis, published in 2024, examined:
25 clinical studies with a total of 1,184 participants.
Of these, 21 studies could be statistically combined.
Parameters examined included, among others:
- Plaque index
- Gum parameters
- Streptococcus mutans
- General bacterial counts
Compared to other mouthwashes or oral hygiene measures, possible benefits were shown for individual gum parameters.
For plaque reduction:
Chlorhexidine was more effective than oil pulling.
The crucial point, however, is the certainty of evidence.
The authors rated the overall evidence as:
very low certainty.
Reasons included, among others:
- Small study groups
- Different protocols
- Different oils
- Short study duration
- Methodological weaknesses
- Blinding problems
- Different control groups
There are clinical signals.
However, the confidence with which we can derive general recommendations from this remains low.
What does more recent research from 2026 say?
A systematic review published in February 2026 examined traditional oral hygiene practices and also considered oil pulling.
A total of:
31 studies
on various traditional oral hygiene methods were included.
For oil pulling, the evaluated data mainly came from studies using:
Sesame oil
and:
Coconut oil.
The authors described possible or moderate short-term changes in microbial and gum parameters.
At the same time, they emphasized:
- Methodological differences
- Different study designs
- Limited long-term data
- The need for better-standardized investigations
The work therefore does not justify equating it with modern basic dental care.
The more recent literature confirms one thing above all:
Oil pulling is scientifically investigable and possibly interesting as a complementary routine, but the evidence remains heterogeneous.
New Studies 2025 and 2026 | How do they change the assessment?
Since the older review articles, further clinical data have appeared.
They make the picture more interesting.
But they do not make it definitive.
2025 | Olive oil with 20 children
A study published in 2025 compared oil pulling with extra virgin olive oil and chlorhexidine in:
20 children aged 6 to 12.
After one month, the authors reported changes in both groups regarding plaque, gingivitis scores, and a so-called Ora test.
The study is interesting as a new olive oil dataset.
But:
- 20 participants is a very small sample size
- There was no untreated or pure water group
- The study lasted only one month
- The Ora test is not evidence that fewer cavity diseases actually occur
The study must therefore not be formulated as proof that olive oil prevents cavities.
June 2026 | Oil vs. distilled water with 80 adults
A randomized pilot study examined:
80 people with gingivitis.
The oil group used sesame oil or a sesame-based tooth oil.
The control group rinsed with:
Distilled water.
Over eight weeks, questionnaire scores for oral-related quality of life improved in both groups.
Crucially:
There was no statistically significant difference in the total score between oil and water at the examined time points.
This is scientifically valuable because it shows that an improvement within an oil group does not automatically prove a specific oil effect.
July 2026 | 100 people in a controlled plaque-growth model
Another randomized study with:
100 healthy dental students
compared chlorhexidine, coconut oil, black cumin oil, turpentine oil, and distilled water over four days without mechanical dental care.
Olive oil was not included in this study.
The result is nevertheless important for the general oil-pulling debate.
Chlorhexidine inhibited plaque significantly more than all tested oils and distilled water.
No significant differences were shown between the oil groups and water regarding plaque control.
The current studies, therefore, do not support a universal strong effect of every cooking oil.
Why different studies seem to give different answers
In oil pulling, very different things are compared with each other.
One study uses:
Sesame oil.
Another:
Coconut oil.
Another:
Olive oil.
Some participants rinse for:
5 minutes.
Others:
10 minutes.
Or:
20 minutes.
Sometimes it is compared against water.
Sometimes against normal oral hygiene.
Sometimes against chlorhexidine.
Some studies run for:
7 days.
Others:
30 or 45 days.
Therefore, a positive result from a single study cannot simply be applied to:
every oil | every application | every person | every duration.
What does the American Dental Association say?
The American Dental Association continues to view oil pulling with caution.
In its current patient information, it writes that there are no sufficiently reliable scientific studies to show that oil pulling:
