Oral B Glide Mint All in One Dental 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.

What Oral B Glide Mint All in One Dental Floss is made of, ingredients and materials
Oral-B Glide All in One is nylon-based dental floss with a mint flavoring applied to the surface. Nylon is a synthetic polymer chosen for floss because it is strong, flexible, and resists breaking between teeth. The mint coating is a flavoring agent added for taste and consumer preference; nylon itself is inert in the mouth and poses no chemical leaching risk under normal use conditions of brief contact with saliva.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Mint flavoring allergens
Mint flavoring can trigger oral irritation or allergic reaction in sensitive individuals, though such responses are rare with topical mouth contact lasting seconds per use.
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.
Nylon microfiber ingestion
Dental floss is designed to be removed before swallowing and fragments small enough to ingest would pass through the GI tract without interaction; no adverse events have been documented for nylon floss.
Formaldehyde / VOCs
Mint flavorings used in food and oral-care products are regulated and formaldehyde use in such applications is not standard; no regulatory warning or recall for this product exists.
Source, ATSDR ↗Heavy metals
Mint flavoring does not require pigmentation; it is typically a colorless or pale extract. No lead, cadmium, or other heavy metal contamination has been reported for Glide floss.

The brand's record and disclosure
Oral-B (owned by Procter and Gamble) has made a public commitment to remove Teflon-type coating and PFAS from its floss products in response to consumer concern about Teflon-family coating additives. The company claims the current formulation is PFAS-free, though this assertion has not been independently verified by third-party testing. P&G has a mixed track record on chemical transparency; they do comply with labeling regulations but have faced criticism on other product categories for slow chemical phase-outs.
How it compares in its category
Most dental flosses are either nylon or natural fibers (silk, bamboo). Traditional Glide floss used Teflon-type coating (a PFAS compound) for its non-stick slip; removal of Teflon-type coating shifts Glide toward the safety profile of conventional nylon floss. Competitors including Tom's of Maine and Radius have received PFAS-free claims from their brands, though Glide's reformulation aligns it with industry movement away from Teflon-family coating. Price and availability favor Glide in mainstream retail.
If you buy it
Use as directed (daily flossing); no special care is needed. Nylon floss is not heated or ingested and does not degrade from normal mouth moisture. Replace the spool when the floss becomes difficult to unwind or frays. If you have concerns about PFAS legacy in older Glide stock, confirm the purchase date and lot code; reformulated products have been in distribution since 2024.
