In a planet in which health tips arrives from so-named specialists on Instagram and Tiktok, it is progressively a lot more complicated to know what is true and what’s not. It is also probable you have just lately occur throughout a video clip on this sort of platforms warning of the harmful dangers of dental floss.
It occurred to me a few weeks ago when my mom came in excess of to my house with a box of $10 “non-toxic” floss. My existing, and less expensive, floss was putting my well being at possibility, she stated. When I requested for more specifics, she stated my floss has “forever substances” in it and people can get into my bloodstream through the act of flossing — or so she heard, on TikTok.
As a typical at my dentist, and two times-a-day flosser, I’ve never been informed to stop applying dental floss (while my dentist a short while ago experimented with to offer me tricky on a h2o flosser). Guaranteed adequate, a research on TikTok yielded a cascade of videos echoing what my mom explained to me. It’s correct that The Facilities for Disease Control and Prevention (CDC) cites dental floss on a record of goods that could consist of PFAS, but does that indicate that said floss is toxic and my wellness is at hazard to be compromised in return? Is shelling out extra for a non-toxic floss far better?
Substances like PFAS and PFOA (perfluorooctanoic acid) are termed forever chemicals due to the fact they fundamentally do not crack down both in the all-natural setting or in our personal bodies. From a technological standpoint, it’s this longevity that will make them so popular. Placing PFAS in a fabric will make them additional secured versus staining. PFAS on a cooking pan can develop non-stick coatings. I have PFAS to thank for the invention of water-resistant mascara. And however, their popularity comes with a significant expense to human health and fitness. Without end chemical compounds have been connected to significant health troubles like cancer, substantial blood strain, infertility, high blood stress, liver condition and small sperm count. Unfortunately, researchers suspect PFAS are everywhere you go and almost indestructible. Right until not too long ago, they’ve been virtually not possible to ruin.
“This is the very first examine to display that utilizing dental floss containing PFAS is connected with a higher body stress of these toxic chemical substances.”
It turns out that TikTok videos claiming dental floss is poisonous really do not just stem from the truth that so numerous items are whole of permanently substances. In 2019, a review posted in the Journal of Publicity Science & Environmental Epidemiology located that women of all ages who flossed with Oral-B Glide dental floss had bigger degrees of PFHxS (perfluorohexanesulfonic acid), a type of PFAS, in their bodies when compared to individuals females who did not. Researchers who performed the examine calculated 11 distinctive PFAS chemical compounds in blood samples taken from 178 center-aged females.
To greater have an understanding of the relationship in between flossing and PFAS ranges in blood, the scientists proceeded to exam 18 dental flosses for the presence of fluorine, a PFAS marker, employing a procedure named particle-induced gamma-ray emission (PIGE) spectroscopy. Six examined optimistic for fluorine — including all three Glide goods.
“This is the initially review to clearly show that employing dental floss made up of PFAS is related with a better system load of these poisonous substances,” claimed direct writer Katie Boronow.
In the research the authors stated extra study was necessary to superior have an understanding of the probable of PFAS in floss traveling into saliva and remaining ingested. In an FAQ about the study, the authors more elaborated on why they thought floss was the perpetrator of higher PFAS stages in the girls in the initial spot. In fact, due to the fact persons are frequently uncovered to PFAS from many sources, it could have been some thing else. But the scientists explained that they applied a model exclusively to come across out how a lot publicity can be attributed to every single source, which would disqualify other sources. Utilizing the exact same product, the scientists located that owning stain-resistant carpet or furnishings, or residing in a city with a PFAS-contaminated drinking drinking water source, were being also linked to elevated PFAS stages. Among African People, ingesting food stuff organized in coated cardboard containers had been joined to greater PFAS concentrations.

“Our design showed that there was a statistically major affiliation amongst flossing with Oral-B Glide and bigger blood concentrations of PFHxS,” the authors mentioned. “This indicates that some of the publicity arrived from flossing.”
“Our product confirmed that there was a statistically major association in between flossing with Oral-B Glide and increased blood concentrations of PFHxS. This indicates that some of the publicity came from flossing.”
Experts at the Silent Spring Institute, a investigation business targeted on uncovering environmental triggers of breast most cancers and other wellness-related subject areas, mentioned they 1st suspected that dental flosses were made with PTFE for a wide variety of causes. 1st, Glide floss is a solution manufactured by Gore (known by customers for its watertight “GORE-TEX” technological know-how), which can make a assortment of consumer and industrial products applying polytetrafluoroethylene (PTFE) — far more usually recognized by its trade identify, Teflon. On the Oral B web page, it lists Polytetrafluorethylene floss (PTFE) as a variety of dental floss and describes the material as one particular that “slides concerning the teeth conveniently and is fewer likely to shred compared to standard floss.”
Because this examine, there haven’t been any added studies posted in a peer-reviewed journal precisely focusing on dental floss and PFAS. However, in September 2022, a wellness weblog called Mamavation tested 39 diverse tooth floss solutions for fluorine, and discovered that 13 out of 39 products and solutions had indications of PFAS. On the large finish, Oral-B Glide tested to have 248,900 components for each million (ppm) of fluorine. (Salon arrived at out to Glide and failed to acquire a response before publication).
“Finding natural and organic fluorine above 240,000 ppm in any product or service meant to go inside of your mouth and thus could be conveniently ingested is pretty regarding,” Linda Birnbaum, scientist emeritus and previous director of the National Institute of Environmental Wellbeing Sciences and Countrywide Toxicology System, said at the time. “These levels that we are observing from some of these dental floss products do not reflect stages that are risk-free for human intake.”
“There is no rationale for makes to continue to pollute the environment and our bodies by introducing unnecessary, toxic ‘forever chemicals’ to products like dental floss.”
Birnbaum reported PFAS could be creating up inside shoppers every time they floss their tooth, “creating a predicament that can lead to long-term illness,” she claimed.
The excellent information is with the comparatively minimal investigate accessible, scientists are hopeful that not all dental floss has PFAS.
“There are by now a wide selection of models that offer PFAS-free dental floss that operate wonderful,” Katie Pelch, a scientist with NRDC (Natural Sources Defense Council), informed Salon by using email. “There is no cause for brands to continue to pollute the setting and our bodies by introducing unwanted, poisonous ‘forever chemicals’ to items like dental floss.”
Pelch said it is about that some firms are applying PFAS in dental floss. “Floss can be made to slide additional quickly amongst the tooth devoid of jeopardizing publicity to harmful without end substances,” Pelch mentioned, introducing that to steer clear of PFAS in floss, buyers ought to avoid products and solutions promoted as “gliding” or “nonstick” and look as an alternative for merchandise that listing pure waxes.
The just take away is not to halt flossing completely. As a short while ago as 2021 a research claimed that flossing was affiliated with lowered cognitive impairment and dementia. Examining 172 contributors, the scientists wrote “These results emphasize the relevance of preserving the health and fitness of the enamel and not just retaining the tooth.” Teresa Yang, a dentist in Los Angeles, instructed Salon through e-mail she’d like to see a observe-up to this examine “to ascertain the significance of the floss PFA material relative to other resources.”
“Never overreact to one locating from a study of fewer than 200 women,” Yang told Salon. “Somewhat, hold out for additional investigate that both confirms or dispels the original findings and offers a lot more concrete and certain info.”
Yang explained flossing is “a single of the best items you can do for your over-all wellbeing.”
But experts say this is however one more illustration for the need to have of restrictions on PFAS.
“In the upcoming, it need to turn into a lot easier to identify PFAS-absolutely free floss, as more states enact rules to reduce unneeded takes advantage of of PFAS,” Pelch explained. “Minnesota lately turned the first state to ban PFAS in dental floss, beginning in 2025.”
