Woom Ortho+ Dental Floss
Lower PFAS concern for traditional dental floss; no red flags detected.
Woom Ortho+ is a standard nylon/polyester dental floss with no known Teflon-family coating coatings or water-resistant treatments that would require PFAS. The brand makes no PFAS claims and no independent lab testing is publicly available.

The full breakdown
What it's made of and why it matters
Woom Ortho+ is a nylon or polyester-based dental floss, typical for the category. Nylon floss does not leach plasticizers like BPA or phthalates into saliva under normal use because it is not designed to soften or flex in ways that degrade the polymer matrix. Unlike some coated flosses, unfluorinated nylon carries no synthetic fluoride residue risk. The primary material concern is physical durability and coating integrity, not chemical migration.
The brand's record and disclosure
Euthymol is a heritage oral-care brand with a long history but minimal public transparency on ingredient sourcing or safety testing. No major recalls or safety controversies have been documented for Woom Ortho+ dental floss. The brand does not prominently disclose third-party certifications (e.g., from dental associations or environmental audits), nor does it publish PFAS reduction statements, though this is uncommon in the dental floss category overall.
How it compares in its category
Most dental flosses (nylon, polyester, or tape variants) present similar low chemical hazard profiles because they contact oral tissues only briefly and are not ingested. Woom Ortho+ is neither premium-positioned nor flagged as eco-certified, placing it in the mainstream mass-market segment. Competitors with explicit certifications (e.g., organic or non-plastic flosses) offer differentiation, but Woom Ortho+ carries no documented safety disadvantage relative to conventional alternatives.
If you buy it
Use normal flossing technique; no special precautions are required. Discard the spool or roll after use; dental floss is single-use and should not be stored in high-heat or direct sunlight to prevent polymer brittleness, though this is uncommon in bathrooms. Replace the product as it frays or loses effectiveness, typically every 1-3 months depending on usage. Store in a cool, dry place to maintain structural integrity.
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.”
Polyester or nylon polymer degradation
No evidence of floss fibers fragmenting into microplastics during normal use or storage. Nylon and polyester are chemically stable under oral conditions and do not hydrolyze readily.
Phthalate or plasticizer leaching
Dental floss does not require plasticizers to function; nylon and polyester are inherently flexible. No documented cases of phthalate migration from unfluorinated dental floss into saliva.
Fluoride residue or additive toxicity
Woom Ortho+ is unfluorinated, eliminating concerns about fluoride coating degradation or ingestion via floss fibers. Any fluoride exposure during flossing comes from topical rinses or toothpaste, not the floss itself.
Heavy metals in pigments or coatings
Dental floss typically uses minimal pigmentation and no complex coatings that would introduce lead, cadmium, or antimony. Standard nylon and polyester are not known to concentrate heavy metals.
Formaldehyde or volatile organic compound emissions
Dental floss does not off-gas formaldehyde or significant VOCs; it is not a textured or resin-treated material and is stored at room temperature, ruling out thermal release during normal use.
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.
