Oral-B Glide Pro-Health Deep Clean Dental Floss
Lower-concern product; nylon floss unlikely to contain PFAS, but Oral-B makes no public disclosure.
Oral-B Glide Pro-Health uses nylon monofilament as its primary material, which is not a typical PFAS-bearing substrate. Dental floss generally poses minimal PFAS risk compared to water-resistant textiles or non-stick cookware.

The full breakdown
What it's made of and why it matters
Oral-B Glide Pro-Health uses nylon monofilament as its core material, a synthetic polymer that is chemically stable and not designed to leach into oral tissues under normal use. Nylon does not contain BPA, phthalates, or other known endocrine disruptors in its base polymer form. The floss is coated with wax (typically paraffin or synthetic wax) and flavoring agents to improve texture and user experience. Since dental floss spends seconds to minutes in the mouth and is not swallowed, systemic exposure to any potential leachables is minimal.
The brand's record and disclosure
Oral-B (owned by Procter & Gamble) does not publish detailed material safety data sheets or make specific public disclosures about PFAS or other chemical additives in dental floss products. The brand has faced no major recalls or safety controversies specific to floss in recent years and holds no third-party certifications (such as NSF or EWG verification) for this category. P&G's general corporate sustainability reporting does not transparently address PFAS use in oral care, leaving some uncertainty about processing aids or legacy manufacturing chemicals.
How it compares in its category
Dental floss is a low-exposure product by design; most alternatives (silk, polytetrafluoroethylene, nylon, or tape variants) carry similar or lower risk profiles than this nylon monofilament. Silk floss is sometimes marketed as 'natural' but biodegradability does not guarantee safety during use. Fluoridated versions of nylon floss (like Glide's fluoride variants) add no additional known hazards. This product sits in the mainstream, non-specialized segment with no standout claims that would elevate or reduce risk relative to comparable drugstore brands.
If you buy it
Dental floss requires no special storage, heating limits, or maintenance; standard room temperature is appropriate. Replace the spool if wax degrades, frays become visible, or floss loses its slide (typically every 3-6 months depending on use frequency). Do not swallow floss; supervise children under age 8 to ensure they do not ingest it. No special precautions are needed for pregnant users or those with oral sensitivities, though individuals with contact allergies to nylon or fragrance additives may experience irritation and should test a small amount first.
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 and flavor additives
Oral-B Glide includes mint flavoring and fragrance compounds, but no specific allergenic or sensitizing agents have been reported in post-market surveillance. For users with fragrance sensitivity, unscented alternatives exist.
Nylon degradation or microfiber shedding
Over time, monofilament nylon can fray or shed fibers, particularly if floss is reused or stored improperly. Shed fibers are swallowed in trace amounts and pose no known systemic toxicity, but users with dysphagia or swallowing disorders should use floss under supervision.
Wax coating composition and leaching
Floss is coated with food-grade wax to aid sliding; paraffin and synthetic wax are recognized as safe by FDA for food contact. No credible reports of leaching of wax components during normal flossing use.
Teflon-type coating or Teflon-family coating contamination in nylon
This product is marketed as nylon monofilament, not Teflon-type coating or polytetrafluoroethylene (Teflon-type coating is a separate floss category). Cross-contamination during manufacturing is not a documented concern for this specific product line.
Ingestion of floss material
Accidental or intentional swallowing of dental floss is rare but documented in medical literature, typically causing no harm if single strands; however, large volumes or knotted floss can create intestinal obstruction. This is a user-behavior hazard, not a product defect.
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.
