Dental experts are cautioning against the recent resurgence of oil pulling, an ancient Ayurvedic practice that has gained popularity through online wellness trends. While the ritual involves swishing edible oils for up to 20 minutes, the American Dental Association reports no reliable scientific evidence that it can whiten teeth or prevent cavities.
The 20-minute Ayurvedic ritual returning to wellness trends
The practice of oil pulling has seen a significant comeback as consumers increasingly seek out "natural" alternatives to traditional hygiene. Rooted in Ayurvedic medicine, the ritual involves swishing oils such as coconut, sunflower, or olive oil around the mouth for as long as 20 minutes before spitting the mixture out.
Proponents of the practice believe that the oil "pulls" toxins and impurities from the mouth, specifically targeting plaque buildup—a combination of bacteria and food particles. Historically, this was thought to detoxify the entire body because of the known link between oral health and systemic well-being. However, as the source reports, the rise of modern toothpaste in the early 20th century largely rendered this ritual obsolete by providing a medically proven way to strengthen teeth.
What the 2022 meta-analysis says about bacterial coounts
Scientific scrutiny of the practice has yielded mixed, though ultimately inconclusive, results. A 2022 meta-analysis did find that oil pulling can lead to a decrease in the number of bacteria present in the mouth. However, the report notes that there is limited evidence to suggest that this reduction translates into decreased gum inflammation or less plaque buildup when compared to standard hygiene routines.
The American Dental Association emphasizes that while bacterial counts may drop, there is still no reliable data to support the claim that oil pulling prevents periodontal disease or cavities. Without more randomized protocols involving larger patient groups, the practice remains a matter of anecdotal wellness rather than clinical necessity.
Dr. Matthew Messina on the superiority of fluoride and toothpaste
Dr. Matthew Messina, a consumer advisor for the American Dental Association and director of Ohio State Upper Arlington Dentistry, suggests that the ritual is essentially a "waste of time" in the context of modern medicine. He points out that while oil pulling was "better than nothing" before the invention of toothpaste, it cannot compete with the benefits of modern oral care products.
According to the report, Messina recommends a regimen centered on brushing twice a day with fluoride toothpaste and flossing once a day. he notes that traditional mouthwashes , which often contain antibacterial ingredients, can serve as a helpful supplement to these habits , whereas oil pulling offers little beyond the basic cleaning provided by a toothbrush.
The risk of a "false sense of protection" near San Diego
Beyond the lack of efficacy, some dental professionals worry about the psychological impact of the trend. Dr. Kami Hoss, a dentist and orthodontic specialist based near San Diego, argues that the practice may provide a "false sense of protection" to users. Hoss questions whether the time spent on the 20-minute oil ritual is better spent on scientifically proven methods that offer guaranteed rewards.
One interesting, albeit unintentional, side effect mentioned by Messina is that some patients brush more thoroughly to remove the lingering oily sensation in their mouths. While this may lead to better hygiene, it remains an indirect and inefficient way to achieve oral health goals. The central question remains: how much time are users sacrificing for a ritual that lacks the clinical backing of a simple fluoride rinse?
