The Humble Co. Dental Floss Picks
Lower-concern product; standard dental floss pick with no known PFAS applications, but brand offers no transparency.
Humble Brush's floss picks are simple nylon-filament dental tools with plastic handles, materials not typically treated with PFAS. Dental floss itself has minimal reason to contain Teflon-family coating or water-resistant coatings.

The full breakdown
What it's made of and why it matters
Humble Co. floss picks use nylon filament paired with plastic handles, a conventional material combination for this product type. Nylon is a synthetic polymer that does not leach harmful chemicals during normal oral use since it makes only brief contact with saliva and does not involve heat exposure. The plastic handles are not ingested and face no documented leaching risk under typical flossing conditions, unlike food-contact plastics.
The brand's record and disclosure
Humble Brush markets itself as an eco-conscious brand focused on sustainable dental care, but public disclosure on material sourcing, manufacturing standards, and chemical safety testing is minimal. The company does not appear to publish third-party certifications (such as ISO, FDA clearance details, or toxicology reports) for its floss products on readily available channels. No recalls, safety alerts, or substantiated safety controversies are on record for Humble Co. dental floss picks.
How it compares in its category
Nylon floss picks are the industry standard and pose no greater chemical risk than competitors from other brands; this product sits in the mainstream middle of the category. Alternatives include traditional string floss (also typically nylon), wooden picks (minimal chemical concern but splinter risk), and plastic-handled picks from major manufacturers (similar material profile). The distinguishing factor for Humble Co. is branding around sustainability rather than any safety advantage or disadvantage relative to conventional floss picks.
If you buy it
Use floss picks as directed without unusual concerns; nylon filament is durable and safe for daily oral use. Store picks in a dry location to prevent mold growth if the container retains moisture. Replace the pack when filament becomes frayed or picks feel less sturdy, typically every few months depending on frequency of use. No special care or heat precautions apply to this product, as it is never exposed to cooking temperatures or intense conditions.
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.”
Nylon filament degradation and ingestion risk
Nylon floss picks are engineered to resist breakage during normal flossing; no widespread reports of filament fragments being swallowed or causing harm exist in the dental product safety literature for this product type.
Plastic handle leaching (BPA, phthalates)
Floss pick handles do not contact food, beverages, or heat and are not ingested; BPA and phthalate leaching risk is negligible under normal use conditions. Humble Co. does not disclose handle plastic type (e.g., polystyrene, polypropylene) publicly, but standard dental pick plastics are not documented sources of chemical migration in saliva.
Mold and bacterial growth on handles
Floss pick handles stored in humid bathrooms or wet conditions can harbor mold or bacteria if not dried between uses; this is a hygiene issue rather than a chemical hazard and affects most reusable or multi-use floss products equally.
Colorants and dyes in handles
If Humble Co. floss picks are pigmented or colored, the colorants are applied to non-food-contact plastic and are not documented as a concern for this product category. No testing results or recalls indicate harmful dye migration from dental floss pick handles.
Manufacturing residues or processing aids
Standard nylon and plastic dental products are subject to FDA oversight, but Humble Co. does not publicly disclose residue testing or process verification. No specific contamination reports are on record for this brand's floss picks.
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.
