Where these two actually differ
- We flag Fragrance allergens or undisclosed additives and Microbial growth if floss is stored damp on the Floss & Ploss and not on the Listerine.
- We flag Fragrance allergens (menthol/mint flavoring) on the Listerine and not on the Floss & Ploss.
- The Floss & Ploss is Dental floss (plant-based or silk) and glass case where the Listerine is Nylon filament (standard dental floss), which is most of the difference in these two grades.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
