Oil Pulling (Gandusha): The Ayurvedic Oil Mouth Rinse

Oil pulling consists of swishing a tablespoon of vegetable oil around the mouth for 5 to 20 minutes, then spitting it out. Its most plausible benefits concern oral hygiene: less dental plaque, fresher breath, less sensitive gums. The Ayurvedic tradition, which practices it under the names gandusha (mouth full, held still) and kavala (oil swished around), credits it with broader virtues — detox, glowing skin, a clear voice — that science has not confirmed.

Small clinical trials suggest that oil pulling reduces oral bacteria and plaque comparably to some mouthwashes, without alcohol or a harsh taste. It is an interesting complement to brushing, never a replacement. Here is the practice, step by step.

What are the benefits of oil pulling?

• Dental plaque and gums: the best-studied effect. Several small trials find a reduction in plaque and gingivitis after 2 to 4 weeks of daily practice. The research remains preliminary, but the mechanism is plausible: the oil traps bacteria and disrupts their sticky film.
• Breath: reducing the bacteria responsible for sulfur compounds often translates into more neutral breath — especially if you combine it with tongue scraping, which targets the coating on the tongue.
• Dry mouth and comfort: the practice stimulates salivation and lubricates the mucous membranes, something tradition values particularly for Vata constitutions.
• Whitening, general detox: no solid data. Oil does not "pull" toxins from the body through the mucosa; if your teeth look cleaner, it is the mechanical effect on plaque, not chemical whitening.

Coconut oil or sesame oil: which should you choose?

Both work; the choice comes down to taste, season and your profile.

Criterion	Sesame oil	Coconut oil
Tradition	The reference oil of the Ayurvedic texts	A more recent adoption, very popular
Taste	Pronounced, vegetal	Mild, easier for beginners
Ayurvedic energy	Warming, calms Vata	Cooling, suits Pitta
Practicality	Liquid all year round	Solid below 25 °C / 77 °F (melts in the mouth)
Quality to look for	Virgin, first cold pressing	Virgin, not deodorized

In practice: start with coconut if the taste of sesame puts you off, switch to sesame in winter or if you tend to feel cold and wired. Virgin sunflower oil is a decent neutral alternative. In every case, choose a virgin, food-grade oil: this is a product that spends 15 minutes in your mouth.

How to do oil pulling, step by step

1. In the morning, on an empty stomach, before breakfast and ideally after tongue scraping. That is its classic place in the dinacharya, the Ayurvedic morning routine.
2. Take 1 tablespoon of oil (1 teaspoon is enough to start with, or for a teenager).
3. Swish it gently between the teeth and cheeks, without forcing or puffing out the cheeks: the jaw should stay relaxed.
4. Duration: 5 minutes is plenty to begin with, 10 to 20 minutes for regular practitioners. Use the time to make tea or take your shower.
5. Spit it into a trash can or a paper towel, never into the sink: the oil solidifies and clogs the pipes. Do not swallow — the oil is loaded with bacteria.
6. Rinse with warm water, then brush your teeth as usual.

Frequency: the traditional ideal is daily, but 3 to 4 times a week already produces noticeable results for breath and that clean-mouth feeling. Allow 2 to 3 weeks of consistency before judging.

How often and for how long?

Tradition makes oil pulling a daily morning gesture: its value lies in regularity rather than in the length of a single session.

Parameter	Traditional benchmark	Note
Frequency	Daily, on an empty stomach in the morning	Regularity matters more than intensity
Duration per session	10 to 20 minutes	Start with 5 minutes and build up over one to two weeks
Amount of oil	1 tablespoon	Sesame or coconut, at room temperature
Time before judging	At least 1 to 2 weeks of daily practice	The duration tested in the study below

A small randomized trial by Asokan and colleagues, published in 2008 in the Journal of Indian Society of Pedodontics and Preventive Dentistry, had 20 adolescent boys either swish sesame oil or use a chlorhexidine mouthwash for 10 minutes every morning before brushing. In the oil group, Streptococcus mutans counts in dental plaque fell significantly after one and two weeks; the reduction in saliva was significant only in the chlorhexidine group (see the study). It is a very small sample, and the oil was used in addition to brushing, never instead of it.

Gandusha: how often?

In gandusha, the mouth is filled with oil and held still, traditionally until the eyes or nose begin to water, a sign that stays indicative rather than a goal to reach every time. Its classic place is every morning, after tongue scraping and before breakfast; 3 to 4 sessions a week is a realistic minimum, and a more intensive course is kept for limited periods (irritated throat, fragile gums), not for permanent use. Its effect on plaque depends on repetition: after several weeks off, it is not dangerous, but the benefits on breath and gum comfort gradually fade.

Kavala: how often?

In kavala, the liquid is moved actively; when it is used as a gargle with a warm liquid (warm salt water, diluted triphala decoction, water with a pinch of turmeric) held at the back of the throat, tradition makes it an occasional practice rather than a daily ritual: 2 to 3 times a day for a few days at the first signs of an irritated throat, with a warm rather than hot or cold liquid, and never swallowed. High fever, intense pain when swallowing, difficulty breathing, or no improvement after 3 to 4 days call for a doctor, not more gargling.

No study has tested kavala with an herbal decoction. The closest data concern plain water: in a randomized trial by Satomura and colleagues (American Journal of Preventive Medicine, 2005), 387 healthy adults gargled with water or diluted povidone-iodine at least three times a day, or did nothing, for 60 days in winter; the water-gargling group had about a third fewer first upper respiratory infections than the control group, while povidone-iodine made no significant difference (see the study). This is prevention with water, not the treatment of a throat that is already sore, so it transfers to traditional kavala only with caution.

What do dentists say about oil pulling?

The prevailing position in dentistry is cautious but not hostile: oil pulling is harmless as long as it is added to brushing (twice a day with a fluoride or otherwise suitable toothpaste) and flossing. Dental associations point out that the evidence is insufficient to recommend it officially, and above all that it treats neither cavities, nor receding gums, nor infections. Tooth pain, persistent bleeding gums or an abscess belong with a dentist, not an oil ritual.

Common mistakes and precautions

• Replacing brushing: mistake number one. Oil pulling is a complement, full stop.
• Swallowing the oil: it contains the bacteria you have just dislodged. Spit it out, always.
• Overdoing duration or intensity: sore jaws and nausea guaranteed. Start short and gentle. If you have a jaw-joint (TMJ) disorder, keep sessions brief or abstain.
• Young children: not recommended before the age at which a child can reliably spit (risk of aspirating a fatty liquid, which can be serious).
• Allergies: sesame and coconut are allergens; choose an oil you already consume without problems.
• Morning nausea: common at first; reduce the dose and duration. If it persists, this practice is simply not for you.

Pregnancy: the practice itself is not worrying with a food-grade oil, but first-trimester nausea does not mix well with it — listen to your body, and if in doubt talk to your midwife or doctor. For an overview of the rules of caution in Ayurveda, see our safety guide.

How to fit oil pulling into your routine without losing your morning

The secret is habit stacking: tongue scraping (30 seconds), oil in the mouth, then shower or breakfast prep while the oil does its work. The ritual thus "costs" no extra minutes at all. If you are new to Ayurveda, this is one of the simplest daily practices to adopt, along with tongue scraping and the morning glass of warm water — our article on Ayurvedic daily habits suggests a realistic order of adoption.
