What Is Oil Pulling?
Oil pulling is a traditional Ayurvedic oral hygiene practice that involves swishing a tablespoon of oil (typically coconut, sesame, or sunflower oil) around the mouth for 10–20 minutes, then spitting it out. Proponents claim it whitens teeth, freshens breath, kills bacteria, and even improves overall health.
But how much of that is backed by evidence? Let's separate fact from folklore.
The Claimed Benefits
- Reduced plaque and gingivitis
- Fresher breath (reduced halitosis)
- Whiter, brighter teeth
- Reduced harmful oral bacteria
What Research Suggests
Plaque and Bacteria Reduction
This is where oil pulling has the most credible support. Several small-scale studies have found that oil pulling — particularly with sesame or coconut oil — can reduce Streptococcus mutans (a key cavity-causing bacterium) and plaque levels when practised consistently. The leading theory is that bacteria get "trapped" in the oil and expelled when you spit.
However, it's important to note that these studies are generally small and short-term. Oil pulling is not a replacement for brushing and flossing — it works best as a complementary practice.
Teeth Whitening
This is where the evidence is thinner. There are no well-controlled clinical studies demonstrating that oil pulling bleaches or chemically whitens teeth the way peroxide-based products do. Oil does not contain bleaching agents and cannot break down pigment molecules embedded in enamel.
That said, some people report their teeth looking brighter after regular oil pulling. The likely explanation: oil may help remove surface stains and reduce stain-attracting plaque, which can improve the appearance of teeth without actually changing their colour.
Fresh Breath
Evidence here is more encouraging. Oil pulling has been shown in some studies to be comparable to chlorhexidine mouthwash in reducing volatile sulphur compounds (the main cause of bad breath). If fresh breath is your goal, oil pulling may genuinely help.
How to Try Oil Pulling
- Choose your oil: Coconut oil is the most popular choice due to its pleasant taste and lauric acid content, which has antimicrobial properties. Sesame oil is the traditional choice.
- Start in the morning: Do it on an empty stomach, before brushing your teeth.
- Use about one tablespoon of oil. If you're new to it, start with a teaspoon.
- Swish gently for 10–20 minutes. You don't need to swish vigorously — gentle movement is fine.
- Spit into a bin (not the sink — oil can clog drains). Never swallow the oil, as it contains the bacteria you've pulled out.
- Rinse with warm water, then brush your teeth as normal.
Is It Safe?
Oil pulling is generally considered safe for most adults. There are no serious reported side effects from the practice itself. A few things to keep in mind:
- Don't swallow the oil after pulling — it contains bacteria and toxins.
- People with certain jaw disorders may find prolonged swishing uncomfortable.
- It should never replace professional dental care or regular brushing and flossing.
The Honest Verdict
Oil pulling is a low-risk, low-cost addition to your oral care routine that may contribute to fresher breath, reduced plaque, and a slightly brighter appearance. However, if your primary goal is noticeable teeth whitening, you'll need to pair it with proven whitening methods. Think of oil pulling as a wellness ritual that supports oral health — not a standalone whitening treatment.
