Oral B Glide Pro Health Comfort Plus Floss
Lower concern; traditional floss formula with no known PFAS drivers, but brand offers no transparency.
Oral-B Glide Pro-Health uses a polyester-nylon filament with wax coating, materials not inherently associated with PFAS. The brand does not disclose PFAS content or make PFAS-free claims. No third-party testing or certifications for PFAS are publicly available.

The full breakdown
What it's made of and why it matters
Oral-B Glide Pro Health Comfort Plus uses polyester filament coated with wax (typically paraffin or microcrystalline wax) to facilitate gliding between teeth. Polyester is a stable synthetic polymer not prone to leaching into saliva during normal use, and wax coatings are food-safe materials with no known oral toxicity at the exposure levels encountered in flossing. The filament diameter and texture are engineered for comfort rather than efficacy differences that would affect safety.
The brand's record and disclosure
Oral-B (owned by Procter and Gamble) provides minimal ingredient transparency for floss products on packaging or consumer websites, offering no third-party certifications (e.g., NSF, EWG Verified) specific to floss safety. The brand has no documented recalls or safety violations for this product line. P&G's general compliance record is solid, but dental floss remains a category where ingredient disclosure is not standardized or mandated by regulators.
How it compares in its category
Most conventional flosses (Oral-B, Colgate, store brands) use identical or very similar polyester-wax formulations with no measurable safety differentiation. Premium alternatives like silk floss or biodegradable options exist but offer no chemical safety advantage and may introduce different trade-offs (e.g., silk protein allergen risk in rare cases). This product sits squarely in the mainstream, low-hazard segment of the category.
If you buy it
Floss is discarded after use and does not require special storage or handling. Replace the container if the wax coating becomes sticky or the filament frays, as this indicates age-related degradation rather than safety risk. Swallow small amounts of floss or wax incidentally during use poses no documented harm; polyester and paraffin are not absorbed in the gastrointestinal tract.
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.”
Polyester microfiber inhalation
Floss filament is too large and moist to become airborne during normal use. No inhalation hazard is documented for this product or category.
Wax coating residues or contaminants
Food-grade waxes used in floss are approved for oral contact. No heavy metals, pesticides, or toxins have been reported in commercial floss coatings, and Oral-B's production scale suggests routine quality control.
Allergic reaction to polyester or wax
True IgE-mediated allergy to polyester or paraffin wax is exceedingly rare but theoretically possible in sensitized individuals. Contact dermatitis from floss is not clinically documented.
Bacterial colonization on stored floss
Floss is used once and discarded; no long-term storage in moist conditions occurs. Single-use containers do not create biofilm risk unlike reusable water filters.
Lead or heavy metals in filament or coating
Polyester fibers and food-grade waxes do not use heavy metal catalysts or pigments in their formulation. No recalls or test data suggest contamination in Oral-B products.
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.
