Crest Glide Deep Clean Floss To Go Packets Rip-Floss-Toss Cool Mint 30
Skip until brand confirms no Teflon-family coating on filament.
Dental floss typically uses uncoated polyester or nylon, lower concern. Crest discloses no coating or PFAS testing; confirmation from brand would raise confidence.

What Crest Glide Deep Clean Floss Cool Mint is made of, ingredients and materials
Crest Glide Deep Clean uses polyester or nylon filament as its base material. Polyester is a synthetic polymer with no established leaching risk during normal oral use, and nylon is similarly inert in the mouth. The floss is marketed as a finely woven strand without a stated coating, though the company does not explicitly disclose whether Teflon-family coating (Teflon-type coating) or other water-repellent resins are applied to the filament during manufacture. Oral products avoid the heating and degradation risks that affect cookware or food-contact plastics.
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.
Teflon-family coating/Teflon-type coating (undisclosed)
Crest does not publicly state whether polyester or nylon filament is treated with Teflon-family coating (Teflon-type coating) to achieve 'glide' properties. This is a common practice in floss manufacture but remains unconfirmed for this product. Inhalation risk during use is minimal, but PFAS content depends on confirmation.
Microplastic shedding
Polyester and nylon filament are synthetic polymers that may shed microscopic fibers during use. Oral floss is not heated or agitated intensely, but fibers may be ingested incidentally during normal use. No quantitative data on shedding from this specific product is available.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Fragrance allergens
Product lists 'Cool Mint' flavor, which may contain synthetic fragrance compounds. No specific fragrance allergens are disclosed. Oral floss has minimal dermal contact, so sensitization risk is low, but individuals with fragrance sensitivity may prefer unflavored alternatives.
Formaldehyde / VOCs
Polyester and nylon do not require formaldehyde-releasing preservatives in their manufacture. No preservatives are disclosed on the packet. Oral floss does not have the water-contact or microbial-growth risks of liquid cosmetics.
Source, ATSDR ↗Heavy metals
Crest Glide packets are white or light-colored filament with minimal dye content. No heavy metal contamination has been reported for this product or polyester floss in general. The packaging may contain inks, but exposure is not ingestion-relevant.

The brand's record and disclosure
Crest (owned by Procter & Gamble) has no publicly documented recalls or safety violations specific to floss products. The brand does not publish ingredient or material transparency reports for floss and has remained silent on whether their filament includes Teflon-family coating coatings or other synthetic treatments. This silence is the primary concern, as many floss products do use Teflon-family coating to achieve glide properties, but Crest has not confirmed or denied its presence. No certifications (such as FDA substantiation or third-party testing) are advertised on the product packaging or official materials.
How it compares in its category
Oral floss is a minor-use, low-contact cosmetic product compared to toothpaste or mouthwash. Many mainstream floss brands (Oral-B, GUM, Listerine) similarly decline to disclose detailed coating formulations. Brands that explicitly market Teflon-type coating-free or plant-based filament (such as Radius or Tom's of Maine) are more transparent. Crest Glide's ambiguity on filament treatment puts it in the middle of the transparency spectrum for mass-market flosses.
If you buy it
Use floss as directed (once daily, gentle sawing motion) and discard after use. There is no heat exposure, prolonged contact, or reuse that would trigger degradation hazards. A 30-packet supply is single-use, so no maintenance is needed. If you have concerns about Teflon-family coating exposure, contact Crest directly to request confirmation of whether their filament includes Teflon-type coating or Teflon-family coating resins; many manufacturers will provide this information on request even if not published.
