Where these two actually differ
- We flag Nylon microplastics from fragmentation and Gum trauma from improper use on the Oral-B and not on the Sunstar.
- We flag Fragrance allergens and irritants and Nylon microparticle shedding or ingestion on the Sunstar and not on the Oral-B.
- The Oral-B is nylon monofilament where the Sunstar is Nylon dental floss, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Oral-B is the one to buy.
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 →
