Oral B Glide Mint All in One Dental Floss
Lower concern, typical nylon floss without known PFAS indicators.
Oral-B Glide uses nylon floss, a conventional material without disclosed PFAS treatments. No public lab testing or brand claims available to confirm or deny PFAS presence.
We flunk more products than we pass. This one earned its grade. How we grade
Material
Nylon floss, unflavored core with mint flavor coating
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Category baseline
cosmetics is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
What’s reassuring
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Mint flavoring allergenicity
Mint flavoring in oral care products is widely used and well-tolerated; no documented allergic reactions to Glide Mint floss are on record. Individuals with menthol or peppermint sensitivity should opt for unflavored alternatives.
Nylon microfiber ingestion
Nylon floss is designed to break apart during use; small fragments may be swallowed incidentally. Nylon is not bioavailable and passes through the digestive tract without absorption or known toxicological effect at typical exposure levels.
Polyethylene coating leaching
Polyethylene is inert and not known to leach chemicals during oral use at room temperature. Glide floss does not contact hot foods or beverages, eliminating the primary migration pathway.
Heavy metals
No recall, regulatory action, or published testing has identified heavy metal contamination in Glide floss. Mint flavoring and the nylon material itself are not typical sources of lead, cadmium, or arsenic.
Source: FDA ↗Formaldehyde / VOCs
Nylon and polyethylene do not rely on formaldehyde-releasing preservatives or resins. No evidence suggests formaldehyde is present in the floss or its coating.

What it's made of and why it matters
Oral-B Glide is a nylon multifilament floss with a polyethylene coating and mint flavoring applied to the surface. Nylon is a synthetic polymer chosen for floss because it is strong, flexible, and resistant to fraying, making it effective for interdental cleaning. The mint coating is a flavoring agent applied in minimal quantities and presents no documented toxicological concern at the exposure level typical of flossing. The polyethylene coating serves as a glide layer to reduce friction between teeth.
The brand's record and disclosure
Oral-B (owned by Procter and Gamble) does not publish detailed ingredient disclosure or third-party certifications specific to dental floss safety. The brand has not faced recorded recalls or public safety controversies related to this product line. P&G maintains general compliance statements for cosmetic and oral care products but does not volunteer transparency on non-PFAS chemical composition of floss. No independent testing or regulatory findings of concern have been published for Glide floss.
How it compares in its category
Glide is a mainstream, widely-sold dental floss with a safety profile consistent with most commercial nylon flosses on the market. Alternatives such as unwaxed nylon, silk floss, or water flossers carry similar or identical chemical profiles for the nylon or coating materials. Some specialty flosses market organic or plant-based claims, but these remain niche; Glide's standard formulation reflects industry-standard materials. No published data suggests Glide is materially safer or less safe than competing nylon flosses.
If you buy it
Store floss in a cool, dry place to prevent moisture degradation of the packaging or coating. Use as directed (once daily, gentle sawing motion between teeth) and replace the container when floss becomes frayed or difficult to use. Do not heat the floss or expose it to extreme temperatures. Discontinue use if gum irritation or allergic reaction (e.g., mint sensitivity) develops, though such reactions are rare.
