Oral-B Glide Pro-Health Deep Clean Dental Floss
Lower PFAS concern; standard nylon floss with no known Teflon-family coating or water-repellent coating treatment.
Oral-B Glide Pro-Health floss is made from nylon monofilament, a conventional thermoplastic with no inherent PFAS requirement. Dental floss does not require water-repellency, stain resistance, or non-stick properties that typically drive PFAS use in consumer products.

The full breakdown
What it's made of and why it matters
Oral-B Glide Pro-Health uses nylon monofilament (single-strand polymer fiber) coated with wax, typically polyethylene or paraffin-based. Nylon itself is a stable, non-leaching synthetic polymer; wax coating serves as a lubricant and is food-safe and inert in the mouth. Unlike some floss alternatives, this construction avoids natural fiber (silk) variability and synthetic fiber shedding concerns, making it consistent and durable during use.
The brand's record and disclosure
Oral-B (owned by Procter & Gamble) does not publicly disclose detailed ingredient composition or manufacturing certifications specific to Glide floss, nor does it advertise third-party safety testing. The brand has no known recalls, adverse event warnings, or documented contamination incidents for this product line. P&G maintains general safety statements aligned with FDA compliance for oral care products, but transparency on chemical sourcing is minimal.
How it compares in its category
Glide Pro-Health is a mainstream, mid-tier floss positioned between budget nylon and premium/specialty alternatives (silk, charcoal-infused, biodegradable). Compared to unflavored nylon floss, Glide includes a mint flavor (likely synthetic eucalyptol or peppermint oil), which carries negligible oral safety risk. It avoids claims of antimicrobial coatings or heavy wax buildup that some competitors market, keeping chemical exposure minimal.
If you buy it
Store floss at room temperature in a dry environment; wax coating is stable and does not degrade with age or heat. Replace the container when floss becomes frayed, kinked, or difficult to thread (typically every 2-3 months with daily use). Use once daily and discard after single use; no cleaning, boiling, or reuse is recommended. If gums bleed or show irritation, switch to gentler technique or consult a dentist, not the product.
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 fiber fragmentation or ingestion
Monofilament nylon can fray at the cut edge or break during use, creating small fiber fragments that may be swallowed. This is a property of the material itself, not a chemical hazard; fragments are inert but should not occur in normal use. Risk is low if floss is handled correctly and replaced when worn.
Wax coating contamination or additives
Paraffin and polyethylene wax coatings are food-grade and pose no known oral toxicity risk. Oral-B does not disclose specific wax source or whether additives (colorants, fragrances) are included; standard formulations are safe, but proprietary blend details are unavailable.
Mint flavoring or synthetic additive sensitivity
Glide Pro-Health includes mint flavoring, typically synthetic menthol or peppermint oil, which is safe for oral use but may trigger allergic contact sensitivity in rare individuals with fragrance intolerance. No adverse reactions are documented for this product, but risk exists for people with known essential oil sensitivities.
Heavy metals in packaging or dyes
Floss container is typically plastic (polypropylene) with minimal dye; no lead, cadmium, or other heavy metal contamination has been reported for this product line. Standard manufacturing practices for oral care products include heavy metal screening.
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.
