Dental Lace Dental Floss
Lower concern, natural materials, but brand offers no PFAS transparency.
Dental Lace floss is marketed as silk-based with plant-derived waxes (typically beeswax or plant oils), which are inherently low-PFAS materials. However, the brand makes no public disclosure about PFAS testing or chemical-free claims. No third-party certifications addressing PFAS are documented.

The full breakdown
What it's made of and why it matters
Dental Lace floss is constructed from silk fibers coated with plant-based wax, typically candelilla or similar natural wax alternatives. Silk is a protein fiber with minimal leaching risk in the oral environment, and plant waxes avoid synthetic polymer coatings (like nylon or polytetrafluoroethylene/Teflon-type coating) that can release microplastics or problematic residues. The material degrades naturally if swallowed in small amounts, unlike conventional plastic flosses.
The brand's record and disclosure
Dental Lace markets itself as an eco-conscious, zero-waste oral care brand and provides transparent information about its use of silk and plant waxes on product packaging and website. The brand does not publicly address PFAS testing or certification, and no independent third-party certifications (such as NSF, Leaping Bunny, or toxicology validation) have been reported for this product. No product recalls or safety incidents are on record for Dental Lace floss.
How it compares in its category
Most conventional dental floss is made from nylon monofilament or multifilament coated with synthetic wax or petroleum-derived compounds; some brands use Teflon-type coating (Teflon), which can shed microplastics with aggressive use. Silk-based flosses like Dental Lace occupy a small niche in the market and generally avoid the microplastic and synthetic chemical exposure of mass-market alternatives. Plant-wax coatings are inherently lower-risk than synthetic polymer or fluorocarbon finishes, though they may offer slightly less slip than traditional wax.
If you buy it
Dental floss is used in small quantities and not ingested, so systemic exposure to any coating residues is minimal. Store the product in a cool, dry place to prevent wax degradation; silk fibers are durable but will naturally fray over time if repeatedly wetted and dried. Replace the spool when fraying increases or waxing visibly diminishes. Standard daily use poses no known heating, mechanical degradation, or contamination risk beyond normal oral hygiene.
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.”
Microplastic shedding
Silk fiber with plant wax does not shed microplastics; no evidence of particle release or degradation into the oral cavity under normal flossing use.
Heavy metals in natural fiber coatings
Plant waxes (candelilla, carnauba) do not accumulate heavy metals; no data suggests lead, cadmium, or other metals in Dental Lace floss formulation.
Wax coating degradation and leaching
Plant waxes may gradually soften or lose slip with moisture exposure and storage; composition of any additives (dyes, flavorants) in the wax is not publicly disclosed, so minor leaching of undisclosed minor ingredients remains theoretically possible but not documented.
Allergic reaction to silk or natural additives
Silk allergy is rare but documented in sensitive individuals; any flavorants, essential oils, or dyes in the plant wax coating could trigger contact sensitivity in the gingival tissue, though no incidents are on record for this brand.
Bacterial growth on natural fibers if stored damp
Silk is proteinaceous and can support microbial growth if the floss spool is stored in a moist bathroom environment; proper air-dry storage mitigates this risk.
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.
