Curaprox DF 820 dental tape is made from high-performance PTFE (polytetrafluoroethylene), offering ultra-smooth, shred-resistant cleaning for tight or sensitive interdental spaces. Its flat, tape-like structure provides superior gliding and plaque removal with minimal irritation. The non-fraying PTFE material slides easily between even the closest contacts, making it ideal for individuals with tight interdental anatomy, orthodontic appliances, or restorations.
