Low Exposure Risk — Why This Product Category Matters

Conventional toothpaste and mouthwash contain triclosan (an endocrine disruptor), sodium lauryl sulfate (SLS, a skin irritant), artificial sweeteners, and microbeads. The mouth is one of the most absorptive surfaces in the body — chemicals applied to the mouth absorb directly into the bloodstream.

Why We Recommend This Product

RADIUS's natural silk floss is completely natural — no PTFE, no PFAS, no synthetic coatings. Biodegradable. The safest dental floss option for daily use.
