Oral-B dental floss users report a rougher, more plastic-like texture as manufacturers quietly phase out PTFE and PFAS amid mounting consumer pressure and state bans.
Texture Changes in Oral-B Spark User Inquiries Online
A routine discussion on Reddit earlier this year exposed a subtle manufacturing shift that caught daily flossers off guard. Consumers noticed that familiar dental hygiene products suddenly felt different between their teeth. As manufacturers quietly move away from synthetic materials, the everyday user experience has taken a noticeable turn.
It feels more plastic-like, rougher, less smooth.

That altered glide has left some people worried about potential dental damage during routine flossing.
It feels like I’m going to take a tooth along with it when I pull it out.

Replaced Materials and the Push to Remove Fluorinated Compounds
Behind the texture overhaul lies a broader industry retreat from polytetrafluoroethylene, commonly known by the brand name Teflon. PTFE belongs to the broader family of per- and polyfluoroalkyl substances, frequently called forever chemicals
due to their persistence in the environment and the human body.
According to the company, a trademarked Pebax polymer is used to reinforce the fiber and provide strength, durability, and handling performance.
The formulation changes follow years of independent scrutiny. A 2019 study conducted by the Silent Spring Institute in Massachusetts found that women reporting regular use of Oral-B Glide had higher concentrations of PFHxS—another forever chemical—in their blood than non-users. Senior scientist Laurel Schaider noted in an interview that researchers also observed higher PFAS levels among individuals living with stain-resistant home textiles. The environmental group collaborated with Graham Peaslee, a chemist and nuclear physicist at the University of Notre Dame, who tested 18 floss products for fluorine, described by Schaider as the marker of Teflon.
Industry Timelines and Growing State-Level Restrictions
While researchers established correlations between certain floss varieties and blood markers, they did not definitively prove the floss was the primary source. Peaslee noted that the correlation with PFHxS could be related to other behaviors that weren’t controlled in the study.
Even so, major brands began preemptive exits. Based on a statement given to Forbrugerrådet Tænk, a Danish consumer organization, Colgate began phasing PTFE out of its dental floss in the year 2022. Following its own analysis, the organization discovered that several floss brands contained PTFE without mentioning it on their labels. While maintaining that PTFE was a safe ingredient in our dental floss,
Colgate cited consumer concerns when explaining its decision to transition its floss products to PTFE-free fibers.
Regulatory pressure has accelerated these corporate shifts. Minnesota enacted a state ban last year prohibiting the intentional addition of PFAS across 11 consumer product categories, with dental floss explicitly included on that restricted list.
Consumer Guidance and Safer Marketplace Alternatives
When asked for guidance on what shoppers should look for on product packaging, the American Dental Association deferred. Schaider, however, encourages consumers to find a floss that works for them while emphasizing the continued importance of daily oral hygiene.

You should find a floss that works for you because it’s really important to floss,
Schaider said. But for the marketplace, I want to make sure that the floss is as safe as it can be.
