Dr.Collins Perio FlossPics
Lower-concern product; no waterproofing or special coatings typical of PFAS use.
Perio FlossPicks are basic interdental cleaning tools made from wood and nylon bristles, materials not typically treated with PFAS. The brand makes no PFAS claim and provides no third-party testing, but the simple construction and lack of water-repellent or non-stick coatings suggest lower risk.

The full breakdown
What it's made of and why it matters
Dr. Collins Perio FlossPics consist of a bamboo stick handle with nylon bristle floss woven or attached at one end. Bamboo is a natural, untreated wood substrate that carries minimal chemical risk when properly processed; nylon bristles are inert plastics stable at room temperature and unlikely to shed or leach when used as designed in the mouth. The combination avoids common hazard materials like PVC, BPA-containing plastics, or resin-coated wood, making material chemistry straightforward and low-risk.
The brand's record and disclosure
Perioe (the manufacturer) has not published detailed material safety data, certifications (such as ISO, FDA clearance details), or ingredient transparency statements in publicly available sources. No recalls, adverse event reports, or safety controversies have been recorded for this product. The brand's silence on PFAS stance is typical of small oral care manufacturers and does not indicate use; the simple material composition makes PFAS treatment unlikely.
How it compares in its category
Floss picks are one of the lowest-complexity dental care products and carry minimal chemical exposure compared to electric toothbrushes (electronics, batteries), whitening strips (peroxide), or mouthwashes (preservatives, dyes). Bamboo-nylon combinations are considered a safer alternative to plastic-only or resin-reinforced picks. This product sits in the mainstream safety tier for floss picks; no material trade-offs vs. higher-priced competitors.
If you buy it
Store in a dry place to prevent bamboo moisture absorption and mold growth on nylon bristles. Replace individual picks if bristles fray, splinter, or show visible wear; nylon fibers can theoretically become aspiratable if severely degraded, though this is uncommon. Rinse under water after use to remove food debris and allow air drying. Avoid prolonged soaking or dishwasher use, which may degrade the bamboo-nylon bond.
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.”
Bamboo degradation and splinter risk
Natural bamboo can develop surface splintering if wetted repeatedly or stored in high humidity. Splinters are a mechanical hazard, not chemical, but ingestion of wood fragments is unlikely during normal flossing use.
Nylon bristle shedding
Worn or poorly manufactured nylon bristles may shed loose fibers into the mouth. This is a physical hazard (choking/aspiration risk is very low in adults) rather than a toxicological one; nylon itself is biologically inert.
Mold or bacterial growth on bristles
If stored wet or in damp conditions, nylon bristles and the bamboo-bristle junction can develop microbial biofilm. This is a hygiene issue, not a chemical leaching risk; regular drying mitigates this.
Adhesive or binding agent leaching
No information is publicly available about the glue or binding method used to attach nylon bristles to bamboo. If present, typical floss-pick adhesives are not known to leach; however, confirmation from the manufacturer would strengthen this assessment.
Dyes or coatings on bamboo
No records indicate that Dr. Collins Perio FlossPicks use dyes, lacquers, or resin coatings that could introduce heavy metals or formaldehyde resins. Bamboo is often left natural or lightly treated; if colored, food-safe dyes are typical.
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.
