Oral-B Glide Pro-Health Advanced Floss
Lower concern; traditional waxed nylon floss unlikely to contain PFAS, but no brand transparency on coatings.
Oral-B Glide uses nylon filament with wax coating, materials not typically associated with PFAS. However, the brand provides no public disclosure of coating composition or PFAS testing. No third-party certification or independent lab data is available to verify claims.

The full breakdown
What it's made of and why it matters
Oral-B Glide Pro-Health Advanced Floss is constructed from nylon filament coated with wax (typically paraffin or synthetic wax) and flavoring agents. Nylon is a thermoplastic polymer with a well-documented safety profile in oral care applications, chosen specifically because it resists fraying and slides smoothly between teeth. The wax coating serves as a lubricant and flavor carrier; wax itself poses minimal ingestion risk because floss is used briefly in the mouth and most residue is minimal. Nylon does not leach monomers or plastic degradation products under normal oral use, as mouth temperatures remain too low to degrade the polymer.
The brand's record and disclosure
Oral-B, a Procter and Gamble subsidiary, does not publicly disclose detailed ingredient lists or coating composition for this floss product, nor has the brand made specific public commitments regarding PFAS avoidance in floss lines. No major safety recalls or established safety controversies linked to Glide Pro-Health Advanced Floss have been reported in public databases. The lack of transparency on wax formulation means users cannot independently verify absence of fluorochemicals, but standard paraffin waxes used in consumer floss lines are unlikely to contain PFAS.
How it compares in its category
Waxed nylon floss like Oral-B Glide sits in the mainstream of dental floss products and shares the same material class as competitor brands such as Crest Glide and store-brand alternatives. Unwaxed floss (silk or nylon) carries minimal difference in safety risk; the distinction is primarily functional (ease of use and durability). Dental floss in general is a low-exposure product category because it spends seconds in the mouth per use and almost no material enters the stomach; ingestion risk is negligible compared to drinking water, food containers, or cookware.
If you buy it
Use Oral-B Glide Pro-Health Advanced Floss as directed: gently guide it between teeth and along the gumline once daily. There are no heat-related concerns because floss is never heated. Replace the spool when wax coverage visibly wears away or filament begins to fray, typically after several months of regular use. Swallowing small amounts of floss or wax is not a toxicity concern; accidental ingestion of a few millimeters poses no documented risk, though large swallowed lengths could pose a choking hazard.
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.”
Fragrance allergens (in flavoring)
Oral-B Glide Pro-Health Advanced Floss includes flavoring (typically mint or fruit); flavor compounds may contain fragrance allergens that could irritate sensitive oral tissue in rare cases. Contact dermatitis or mouth irritation from floss is uncommon but possible if you have known sensitivity to mint or other common floss additives.
Wax composition transparency
Oral-B does not disclose whether the wax coating is paraffin, synthetic, or blended, and does not explicitly rule out fluorochemical additives in wax formulations. While traditional paraffin wax is unlikely to contain PFAS, absence of public specification means consumers cannot independently verify the coating material.
Ingestion of floss fibers or wax
Accidental ingestion of small amounts of nylon filament or wax during flossing is not associated with documented health effects. Both nylon and food-grade paraffin wax pass through the digestive system without absorption; large swallowed lengths could theoretically pose a choking or blockage hazard, but this is a mechanical risk, not a chemical toxicity risk.
Leaching from nylon polymer
Nylon does not leach BPA, phthalates, or other endocrine-disrupting chemicals under normal oral conditions. The material is inert at mouth temperature and pH, and floss contact time is brief (under 2 minutes daily).
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.
