Oral B Glide Pro Health Comfort Plus Floss
Oral-B says its floss is now made without Teflon-type coating or PFAS, a claim we have not verified.
Oral-B says its Glide floss is no longer formulated with Teflon-type coating and that none of its floss products are formulated with Teflon-type coating or any type of PFAS. We record that as an unverified brand claim. Glide was made with Teflon-type coating for decades, so older packs still on some shelves may predate the change.
Brand says: “Oral-B says its Glide floss is no longer formulated with PTFE and that none of its floss products are formulated with PTFE or any type of PFAS.”

What Oral B Glide Pro Health Comfort Plus Floss is made of, ingredients and materials
Oral-B Glide Pro Health Comfort Plus is a nylon-based dental floss coated to enhance glide and durability. The company states it is now formulated without Teflon-type coating or PFAS, moving away from the fluorocarbon-based slip coatings historically used in premium floss products. Nylon itself is a stable, non-toxic polymer when used as intended in the oral cavity; it does not degrade into hazardous monomers or leach chemicals under normal conditions.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Bacterial/fungal growth on spool
Like all dental floss stored in humid bathroom environments, the container can harbor mold or bacteria if moisture accumulates. This is a storage issue, not a product defect, and is mitigated by keeping the spool dry and sealed.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
PFAS
Oral-B has not publicly disclosed the alternative coating chemistry (wax, silicone, or proprietary polymer) used to replace Teflon-type coating. Without ingredient disclosure, safety of the replacement agent cannot be assessed from available information.
Source, ATSDR ↗Ingestion risk (if swallowed)
Nylon floss is not intended for ingestion and poses a theoretical choking hazard if large amounts are swallowed by young children. However, small fragments have no documented toxicological effect in humans.
Dye or colorant toxicity
No recalls or safety issues reported for colorants used in Oral-B floss. Food-grade or cosmetic-grade colorants are standard in the category and do not pose a hazard during normal oral use.
The full breakdown
The brand's record and disclosure
Oral-B (owned by Procter & Gamble) has made a public commitment to remove PFAS from its floss line, though third-party lab verification of this claim is not yet widely documented in peer-reviewed sources. The brand has no established history of recall or contamination issues specific to this product. Oral-B maintains a reputation for transparency on fluoride content in toothpaste but less detailed public disclosure on floss coating chemistry.
How it compares in its category
Most premium dental flosses (including traditional Glide and competitors like Reach Gentle Glide) historically relied on Teflon-type coating or PFAS-derived coatings for their slip properties. Oral-B's shift to a formulation without Teflon-type coating positions this product ahead of older formulations and aligns with a broader industry trend toward coating alternatives with lower PFAS concern. Waxed and unwaxed nylon flosses without synthetic slip coatings remain the most chemically minimal alternative, though they may be less comfortable for some users.
If you buy it
Use as directed, wind floss around fingers and slide gently between teeth, then discard. Nylon floss is not designed to be swallowed, though small ingested amounts pose no toxicological risk. Store in a dry location to prevent moisture absorption and mold growth in the container. Replace the spool every 3-6 months or when strands begin to fray; this product has no shelf-life concerns but degrades with extended contact with saliva and bacteria.
