Das Experten EXPANDING is a dynamic interdental floss engineered with moisture-activated expansion and adaptive diameter control. Designed for users with tight contacts, irregular tooth spacing, or gingival sensitivity, this floss offers 360° surface cleaning and mechanical biofilm disruption with each pass.
Material & Structural Innovations:
1. Hydrophilic Expansion Fibers (Volume-Gain Technology)
Crafted from high-tensile polyester, the floss expands upon contact with saliva, increasing its effective diameter by up to 100%. This hydrophilic expansion enhances mechanical contact with tooth surfaces, ensuring greater plaque adhesion and scraping effect in variable-width interdental spaces.
2. Manual Thickness Customization (Stretch-Adaptive Control)
Unlike conventional floss, EXPANDING can be manually stretched from both ends, allowing users to tailor its thickness to personal comfort or anatomical need. This feature enables precise control over floss force, width, and contact pressure—ideal for both narrow and wide contacts, and users with implants or crowding.
Oral Health Performance Benefits:
3. Triple-Action Functionality (Cleanse, Stimulate, Freshen)
Cleansing: Expanding mesh structure traps and removes plaque, biofilm, and food residues more effectively than flat or waxed floss types.
Stimulation: Gently massages interdental papillae, promoting blood flow and reducing risk of papillary inflammation.
Deodorization: Removes anaerobic debris and volatile sulfur compounds that contribute to bad breath.
🧪 Validated effect: Users report improved gum tone and reduced interdental bleeding within 2–3 weeks of consistent use.
4. Compatible with Advanced Care Routines
Ideal for combination therapy with interdental brushes, whitening regimes, or orthodontic appliances. Especially suitable for individuals seeking a less abrasive, yet effective method of deep-cleaning.
