You've probably seen someone on TikTok or Instagram swishing a tablespoon of coconut oil around like their life depends on it. It looks weird. It's definitely greasy. But mouthwash oil pulling—the ancient Ayurvedic practice of "Kavala" or "Gandusha"—is moving from the "granola" fringes into mainstream dental hygiene. Honestly, the idea of replacing your minty, alcohol-based rinse with a glob of cooking oil sounds like a recipe for a bad morning. But there is actual science, and a whole lot of history, behind why people are ditching the blue liquid for something a bit more viscous.
People have been doing this for over 3,000 years. It's not a trend. It’s an endurance test for your jaw.
The basic premise is simple: you put a tablespoon of oil in your mouth and pull it through your teeth for about 15 to 20 minutes. Why so long? Because that’s how long it supposedly takes for the oil to emulsify and "pull" out the fat-soluble toxins and bacteria lurking in the crevices of your gums. Most of the nasties in your mouth are single-celled organisms covered in a lipid (fatty) membrane. When you swish oil, those membranes stick to it. It’s like a magnet for gunk.
Does Mouthwash Oil Pulling Actually Work or Is It Just Hype?
If you ask a traditional dentist, they might give you a skeptical look. But if you look at the peer-reviewed data, things get interesting. A study published in the Journal of Contemporary Dental Practice compared oil pulling with coconut oil to chlorhexidine (a heavy-duty prescription mouthwash). The results? Both were effectively equal at reducing Streptococcus mutans, the primary bacteria responsible for tooth decay. That’s wild. A jar of oil from the grocery store held its own against a pharmaceutical-grade rinse.
It's about the biofilm.
Dental plaque isn't just "dirt." It’s a complex colony of bacteria living in a sticky matrix. Most over-the-counter mouthwashes use alcohol to kill everything. It’s a scorched-earth policy. The problem is that alcohol dries out your mouth. A dry mouth is a breeding ground for bad breath because saliva is your natural defense. Oil pulling doesn't kill everything; it mechanically removes the bad stuff while keeping the oral microbiome relatively balanced. Plus, the lauric acid in coconut oil is a natural antimicrobial agent. It’s basically nature’s soap.

The Coconut vs. Sesame Debate
In ancient India, they didn't use coconut oil. They used sesame oil. If you want to be a purist, sesame is the way to go. It contains sesamin and sesamolin, which are potent antioxidants. However, most people today prefer coconut oil for two reasons: it tastes significantly better, and it contains high levels of lauric acid.
I’ve tried both. Sesame oil has this heavy, nutty, almost overwhelming presence that makes the 20-minute mark feel like a marathon. Coconut oil feels cleaner. It starts as a solid (if it's below 76°F) but melts instantly in your mouth. Just make sure you aren't using the "liquid" fractionated coconut oil if you want the full benefits, as the processing can strip away some of those antimicrobial properties.
Why Your Jaw Might Hurt (And Other Newbie Mistakes)
Don't go full throttle on day one.
Most people try to swish aggressively like they’re using Listerine. Do that for 20 minutes and your masseter muscles will be screaming by minute five. The goal isn't a power wash; it's a slow, rhythmic pull. Relax your face. If your jaw starts aching, you're working too hard. Also, never, ever swallow the oil. By the time you’re done, that oil is loaded with the very bacteria, fungi, and food particles you’re trying to get rid of. Swallowing it is basically drinking a concentrated shot of mouth-waste.
Another huge mistake: spitting it in the sink.

Coconut oil solidifies when it cools down. If you spit it down the drain every morning, you are going to meet a plumber very soon, and they will charge you a lot of money to snake out a "fatberg" from your pipes. Spit it in the trash can. Or outside. Just keep it away from your plumbing.
The "Whiter Teeth" Claim: Fact or Fiction?
This is where the marketing gets a bit ahead of the science. You’ll see influencers claiming that mouthwash oil pulling gave them a Hollywood smile in a week. That’s probably not true. Oil pulling doesn't bleach your teeth like peroxide does. However, because it is so good at removing plaque and surface stains (especially from coffee or tea), your teeth can appear whiter because they are literally cleaner.
It's a gradual change. It’s about health, not just aesthetics.
My gums actually stopped bleeding after I started doing this three times a week. That’s a common anecdote. Gingivitis is caused by the immune system reacting to plaque at the gum line. By reducing that plaque load through the mechanical action of the oil, you're giving your gums a chance to heal. It’s less about the "magic" of the oil and more about the consistency of the cleaning.
A Step-by-Step for the Skeptical
- Pick your oil. Organic, cold-pressed coconut oil is the gold standard for beginners.
- Timing is everything. Do it first thing in the morning before you drink water or eat. Your bacterial load is highest right when you wake up—hence "morning breath."
- Start small. If 20 minutes sounds impossible, start with five. Work your way up.
- The "Pulling" motion. Use your tongue and cheeks to push and pull the oil through the gaps in your teeth.
- The Cleanse. After you spit, rinse your mouth with warm salt water. This helps get rid of the oily film and any lingering bacteria. Then, brush your teeth like normal.
Understanding the Limitations
Let's be real: oil pulling is not a replacement for flossing or professional dental cleanings. It’s an "in addition to" practice. If you have a cavity, swishing oil isn't going to fill the hole. If you have advanced periodontal disease, you need a doctor, not a coconut. Some people also report "healing crises" like skin breakouts or headaches when they start, though the scientific evidence for "detox" symptoms is pretty thin. It's more likely your body just adjusting to a new routine.

Also, be aware of Lipoid Pneumonia. It’s extremely rare, but if you accidentally inhale (aspirate) small amounts of oil into your lungs over a long period, it can cause inflammation. This is why you shouldn't gargle with the oil. Keep it in the front and sides of your mouth.
Actionable Next Steps for Better Oral Health
If you're ready to try mouthwash oil pulling, don't overthink it. Grab a jar of virgin coconut oil from the pantry tomorrow morning. Take one teaspoon (not a whole tablespoon at first, it's too much) and swish while you're in the shower or making coffee. The distraction helps the time pass.
Do this for seven days straight. Pay attention to the "slickness" of your teeth and the freshness of your breath throughout the day. Most people notice a difference in how their tongue feels—less coated, more pink—within the first week. If you hate the sensation, stop. But for the cost of a few cents a day, it's one of the cheapest biohacks available for your long-term dental health.
Consistency beats intensity every time. You don't need a fancy "pulling oil" blend with essential oils and gold flakes. Just simple, pure fat and a bit of patience. Your gums will likely thank you, and your breath definitely will.
