Lower concern; traditional waxed floss rarely uses PFAS, but Sunstar makes no public disclosure.
Sunstar GUM's waxed dental floss is a conventional product with nylon filament and wax coating, materials not typically associated with intentional PFAS use. However, the brand provides no public statement on PFAS avoidance or testing. No third-party verification or certification visible.

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This product is nylon filament coated with wax, typically paraffin or beeswax-based. Nylon does not leach into the mouth during normal use because it is non-porous, chemically inert, and never heated. The wax coating is occlusal only and does not dissolve or fragment in saliva; it serves solely to reduce friction and ease insertion between teeth. This material profile carries minimal chemical exposure risk in the oral cavity.
The brand's record and disclosure
Sunstar is a multinational oral-care manufacturer with no public chemical disclosure policy specific to floss products and no documented recalls tied to chemical hazards in dental floss. The brand has not published statements addressing PFAS use in waxed floss lines, which is standard silence across the category because traditional wax coatings do not rely on PFAS. No third-party testing or certification (e.g., EWG Verified) is on record for this product.
How it compares in its category
Waxed nylon floss is the dominant category standard and carries the same chemical risk profile as unwaxed nylon or silk alternatives. This 12-yard dispenser format is typical bulk packaging; individual spools pose no material difference in safety. Dental floss overall ranks among the lowest-risk oral products because contact time is brief, surface area is minimal, and the material does not contact broken mucosa in normal use.
If you buy it
Store the box in a cool, dry place away from direct sunlight to preserve wax integrity, though degradation does not create hazards. Discard floss if nylon frays or wax separates, as effectiveness declines but not safety. Replace the dispenser every 6-12 months depending on usage frequency. No special precautions are needed; standard brushing and flossing practice applies.
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 microfiber shedding
Nylon floss can occasionally shed microscopic fibers during use. No peer-reviewed evidence links dental floss microplastics to systemic harm, and oral transit to swallowing is brief and involuntary; this remains theoretical rather than reported in the literature.
Wax coating composition (non-PFAS)
Paraffin and plant-derived waxes used in traditional floss are food-grade and present no known toxicological concern at the minute quantities present on a floss strand. Sunstar does not disclose specific wax source, but no contamination or allergen issues are on record.
Dyes or additives in 'Mint' flavor
The mint flavoring may contain synthetic dyes or flavor compounds that contact oral mucosa briefly. No recalls or adverse events are documented for this product; however, mint floss formulations are not independently tested or certified for colorant safety by dental bodies.
Gum irritation from improper use
This is a use-related risk, not a chemical one: aggressive flossing can cause gingival trauma. The material itself (nylon + wax) is inert and non-irritating; the hazard lies in technique, not the product formulation.
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.
