Plant Based/Vegan Floss Refillable Glass Container PFAS-Free (2 Spools/4-
Lower-concern product with explicit PFAS-free claim; no third-party verification limits certainty.
Dental Lace's plant-based floss explicitly markets itself as PFAS-free, and the core material (plant cellulose or silk) has no known PFAS application. The refillable glass container further reduces plastic exposure.
Brand says: “PFAS-Free”

Why this grade
Category baseline
cosmetics is a category where PFAS exposure is more common.
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Dental Lace's plant-based floss is typically derived from cellulose fibers (often bamboo or similar plant sources) rather than nylon or plastic. Plant cellulose fibers are non-synthetic, biodegradable, and carry no known toxicity concerns for oral use. The glass refillable container eliminates plastic packaging waste and poses no leaching risk during storage of the floss itself.
The brand's record and disclosure
Dental Lace has publicly positioned itself as a PFAS-free, sustainable oral care brand and explicitly markets this product as PFAS-free. The brand emphasizes vegan and plant-based ingredients. No third-party certifications (such as NSF, FDA approval for floss materials, or independent PFAS testing) are noted on the product label based on available information, which limits independent verification of claims but does not contradict them.
How it compares in its category
Most commercial dental floss is nylon monofilament, often coated with wax (which may contain PFAS or silicone) and packaged in plastic. Plant-based alternatives like this one avoid synthetic polymer concerns and are genuinely less common. The refillable glass container model is significantly more sustainable than single-use plastic dispensers and reduces cumulative packaging waste per use.
If you buy it
Store the glass container in a dry place to prevent moisture buildup that could degrade plant fibers or encourage mold. Use standard flossing technique; plant-based fibers are generally as effective as nylon but may shred slightly more if forced between tight contacts, adjust tension accordingly. Replace spools when fraying occurs. Glass containers are durable but can break if dropped; handle carefully.
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.”
Dye or colorant toxicity
Plant-based floss may be dyed for visual appeal. No reports of heavy metal contamination or synthetic azo dyes in Dental Lace products are on record; plant-derived and food-grade colorants are standard in this brand category.
Fiber shedding or microplastic generation
Plant-based cellulose fibers may shed small fragments during flossing, particularly if worn or forced. These fragments are biodegradable and pose no systemic toxicity risk, unlike synthetic microplastics, but should not be ingested intentionally.
Glass container breakage and sharp edges
Refillable glass containers can shatter if dropped, creating sharp fragments. This is a mechanical hazard, not a chemical one, but relevant to safe handling and storage, especially in households with children or near sinks.
Oral irritation from plant fiber irritants
Plant cellulose fibers used in vegan floss are generally well-tolerated in the oral cavity. No documented cases of allergic reaction or chronic irritation specific to Dental Lace or similar plant-based flosses are on record.
Bacterial or mold growth on floss spool
If the glass container is stored in a humid bathroom without adequate air circulation, plant-based fibers may retain moisture and support microbial growth over extended periods. Ensure the spools dry fully between uses and store in a relatively dry location.
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.
Formulations and coatings change between production runs. Always check the current label before buying.
