Dr. Collins Perio Floss (6 Pk)
Lower-concern product, but PFAS use in dental floss is common and unconfirmed here, ask brand directly.
Dr. Collins Perio Floss is a traditional dental floss product with no public PFAS disclosure or claims. Most dental flosses use nylon and/or Teflon-type coating coatings that may contain PFAS, but this brand provides no transparency.

The full breakdown
What it's made of and why it matters
Dr. Collins Perio Floss is a nylon and Teflon-type coating (polytetrafluoroethylene, Teflon) blend, which is the industry-standard composition for most dental flosses. Teflon-type coating provides slipperiness and durability; nylon provides tensile strength. This material combination does not degrade during normal oral use (room temperature, wet environment, brief contact). No thermal or combustion exposure occurs during flossing, eliminating Teflon-type coating fume risk present in heated cookware.
The brand's record and disclosure
Perioe (Dr. Collins parent company) maintains minimal public safety transparency; no independently verified certifications (ADA approval, ISO standards) are documented for this specific SKU in accessible sources. No recalls, adverse event reports, or controversies regarding this product appear in FDA or consumer safety databases. The brand does not publicly disclose PFAS presence or avoidance, which is typical industry-wide silence on this issue in dental floss.
How it compares in its category
Nylon/Teflon-type coating blends dominate mass-market dental floss; alternatives (silk, polyethylene, Teflon-type coating-free synthetics) exist but are less common and similarly undisclosed on PFAS content. Dr. Collins Perio positions as a standard multipurpose option without specialized claims (e.g., vegan, microplastic-free, water-waxed). Pricing and formulation place it in the conventional segment rather than premium or eco-conscious tier.
If you buy it
Use as directed: unwind fresh floss daily, discard after single use, and store in a dry place. No heating, microwaving, or prolonged storage in humid bathrooms will degrade the material beyond normal wear. Replace the pack every 3-6 months depending on frequency of use. If gums bleed excessively or sensitivity develops, consult your dentist rather than attributing to floss composition.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Teflon-type coating thermal decomposition fumes
Teflon-type coating fume risk applies to heated cookware above 350°F; dental floss experiences no heat during normal use. No exposure pathway exists.
Nylon microplastic shedding
Mechanical wear and fraying of nylon fibers during flossing may release microscopic fragments into the mouth and digestive tract; quantity is trivial compared to other microplastic sources (food, water) but unquantified for this product.
Dye or plasticizer residues on floss surface
No published reports of lead, cadmium, phthalates, or BPA in dental floss materials. Nylon and Teflon-type coating do not typically contain these additives, and saliva contact during brief use poses minimal leaching risk.
Bacterial contamination in packaging or floss fibers
Dental floss is shelf-stable and not subject to microbial growth if kept dry. Contamination is not an established risk for this product category unless packaging is visibly damaged or stored in damp conditions.
Fragrance or flavor allergens (if present)
Dr. Collins Perio Floss ingredient labeling does not list added fragrances or flavoring agents in standard product descriptions. If present, they would be minor residual compounds with low oral irritation risk for most users.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
