Perioe · Dental Floss
Oral-B Super Dental Floss Pre-Cut Strands
Lower-concern dental floss; nylon is inherently PFAS-free, but brand silence limits certainty.
Dental floss is typically made from nylon monofilament, which does not require PFAS coatings for function. Perioe does not disclose PFAS status. No public lab testing or recalls found for this product. Standard nylon floss presents lower PFAS risk than coated, water-resistant, or specialty dental products.

The full breakdown
What it's made of and why it matters
This product is nylon (polyamide) monofilament floss strand, a synthetic polymer that is chemically distinct from Teflon-type coating (Teflon) and does not require fluorochemical processing. Nylon monofilament is inert in the mouth at normal use temperatures and pH, and the small amount that may be swallowed during flossing poses negligible systemic exposure. The "pre-cut strands" format eliminates the spool and wax coating variables that could introduce contaminants in traditional floss dispensers.
The brand's record and disclosure
Perioe (LG subsidiary) maintains limited public disclosure on material sourcing and PFAS testing for this floss product specifically. The brand has not issued voluntary certifications (such as SafetyGate or independent lab verification) for this category. No recalls or safety incidents are on record for Perioe floss products. The silence on PFAS stance is typical for niche dental brands and does not indicate contamination, only lack of transparency.
How it compares in its category
Nylon monofilament floss is a standard, well-tolerated material in the floss category alongside Teflon-type coating variants. This product avoids the Teflon-type coating fume inhalation concern (though flossing poses minimal thermal risk). Compared to waxed or tape floss, monofilament strands typically shed less debris and are easier to discard; waxed variants may contain synthetic waxes or plant-based coatings that add processing steps but are equally safe at mouth temperatures.
If you buy it
Store pre-cut strands in a cool, dry place away from heat and direct sunlight to preserve nylon integrity over time. Use once per strand and discard; do not reuse or heat-treat. If gums bleed during use, switch to gentler technique rather than assuming floss contamination. Replace your supply every 6-12 months as nylon can become brittle with age and humidity exposure.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Nylon strand shedding or fraying
Monofilament nylon can fray at cut ends or degrade if stored improperly, potentially leaving small fibers in interdental spaces. This is a mechanical nuisance rather than a chemical hazard and does not pose toxicological risk.
Mold or bacterial contamination during storage
Pre-cut strands stored in humid bathrooms without sealed packaging are susceptible to surface microbial growth over months. No specific issue with this brand's packaging is on record; standard hygiene (dry storage, sealed container) mitigates risk.
Allergic sensitization to nylon or residual synthesis chemicals
Nylon monofilament is hypoallergenic in oral use and residual monomers from synthesis are trace and inert. No contact dermatitis or oral allergies are documented for nylon floss in the literature.
Dye or colorant leaching if colored
If this product includes colored strands, pigments are externally applied and minimal ingestion occurs during brief oral contact. No azo dyes or heavy metal colorants have been reported in dental floss formulations from major manufacturers.
Swallowing small strand fragments
Accidental ingestion of short nylon floss pieces is common and poses no chemical or mechanical GI risk; material passes through unchanged and is not absorbed.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
