What Crest Glide Pro Health Mint Mint Floss is made of, ingredients and materials
Crest Glide Pro Health is a nylon monofilament floss, a synthetic polymer that does not absorb saliva or break down in the oral cavity. Nylon floss is inert under normal mouth conditions and does not leach known toxicants during use. The "Comfort Mint" formulation indicates a flavoring additive, but flavoring agents in oral care products are typically food-grade or cosmetic-grade and present minimal systemic exposure risk given the small amount used and brief contact time.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Fragrance allergens (mint flavoring)
Mint flavoring in oral care can trigger contact sensitivity or allergic reaction in susceptible individuals, though incidence is low. No specific adverse reports on record for this product.
Microplastic shedding
Nylon monofilament can fragment under mechanical stress (aggressive flossing, grinding between teeth). Fragments are not ingested in significant quantity and pose negligible internal exposure risk; environmental impact of worn fibers is unquantified.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Nylon monofilament floss does not typically contain formaldehyde-releasing preservatives. No evidence of such agents in Crest Glide Pro formulation on public record.

The brand's record and disclosure
Crest (Procter & Gamble) does not publicly disclose ingredient sourcing, manufacturing standards, or testing data specific to this floss product. P&G maintains general compliance with FDA cosmetic regulations and does not list known safety recalls for this floss line. The brand has not made public commitments to third-party safety certifications or transparency initiatives for oral care products.
How it compares in its category
Nylon floss is the standard material in mass-market dental floss and carries no higher concern than waxed or unwaxed alternatives. Some consumers prefer natural fiber flosses (silk, charcoal-infused plant fibers) on principle, though safety data does not distinguish these as materially superior. The 43.7 oz bulk format is typical for this product type and does not alter hazard profile.
If you buy it
Use as directed; nylon floss is not ingested in meaningful quantity and does not require special storage. Replace the spool once floss is depleted or frayed; degradation is cosmetic, not a safety trigger. No heat or chemical exposure concerns apply to normal oral use. If gum irritation occurs after switching products, it reflects individual sensitivity, not a product defect.
