ORAL B Glide Pro-Health Floss
Lower concern, nylon dental floss carries minimal PFAS risk, but Oral-B has not publicly disclosed composition details.
Oral-B Glide Pro-Health Floss is primarily nylon monofilament, a material not inherently associated with PFAS in dental floss applications. The brand makes no PFAS claims and provides minimal transparency on coatings or additives.

The full breakdown
What it's made of and why it matters
Oral-B Glide Pro-Health Floss is a nylon monofilament product, meaning it is a single continuous strand of synthetic polymer rather than twisted fibers. Nylon monofilament is chemically stable in the oral environment, does not shed microfibers during normal use, and is not subject to the same degradation concerns as some natural fiber flosses. The product is designed for tooth-to-tooth contact and does not come into prolonged contact with food or saliva in ways that would promote leaching of coatings or additives under normal use conditions.
The brand's record and disclosure
Oral-B is owned by Procter and Gamble, a consumer goods manufacturer with mixed transparency on chemical composition. The company does not publicly disclose the full ingredient or material composition of this floss product on its website or packaging, nor does it provide third-party safety certifications specific to dental floss. P&G has faced historical scrutiny over PFAS use in personal care products but has not announced specific reformulation commitments for dental floss lines. No recalls or adverse event reports specific to Oral-B Glide Pro-Health Floss are on record.
How it compares in its category
Most dental flosses are either nylon monofilament (like this product), natural fiber (silk, cotton), or polytetrafluoroethylene (Teflon-type coating, also known as Teflon-based floss). Nylon monofilament products like Glide Pro-Health sit in the mid-safety range: they avoid Teflon-type coating fume concerns and do not degrade into microplastics as easily as some waxed products, but they offer less brand transparency than premium natural-fiber or certified organic alternatives. This product is comparable in material safety to other mass-market nylon flosses from competitors like Colgate and store brands.
If you buy it
Dental floss poses minimal usage risk because contact time is brief and the oral environment is not prone to leaching. Store the floss in a cool, dry place to prevent any potential for wax or coating separation over time. Replace the floss container if you notice visible degradation of the dispenser or spool. If you have sensitive gums or allergies to synthetic polymers, test on a small area first, though adverse reactions to nylon monofilament floss are rare.
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 monofilament degradation and microparticle shedding
Nylon monofilament is stable under normal flossing conditions and does not fragment into microplastics during use. No published reports document microparticle release from Oral-B Glide Pro-Health Floss or comparable nylon monofilament products.
Wax or polymer coating toxicity
Oral-B Glide Pro-Health Floss is waxed for gliding action, but the specific wax composition is not disclosed by the brand. Food-grade and medical-grade waxes used in dental products are generally low toxicity; however, without full ingredient disclosure, minor additives (dyes, flavorings, slip agents) cannot be fully assessed.
Flavor or additive allergenicity
This product includes flavorings and potentially colorants to appeal to consumers. Mint and other flavor compounds are generally recognized as safe, but individuals with fragrance sensitivities or mint allergies should verify ingredients before use. The brand does not list allergen warnings on packaging.
Oral tissue irritation from fibers or edges
Nylon monofilament is smooth and does not splinter; no established reports of gum irritation or tissue damage specific to Oral-B Glide Pro-Health Floss. Risk is comparable to standard dental floss and is not a recognized hazard in this product class.
Teflon-type coating (Teflon) fume or decomposition risk
Oral-B Glide Pro-Health Floss is nylon monofilament, not Teflon-type coating-based floss. This product does not carry Teflon-type coating decomposition or fume inhalation risks associated with heat exposure.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
