Material and safety Made from soft, flexible rubber that provides safer contact during grinding and cleaning. Flexible material adapts to contours, helping reduce hard impacts on the surface being worked on. Design and performance Outer concave profile concentrates contact around the tooth surface for more effective grinding and cleaning. Concave shape helps maintain consistent contact and directs debris away from the work area for clearer visibility and cleaner results. Function and practical benefits Designed to grind and clean tooth surfaces with controlled abrasion and improved surface conformity. Balances flexibility and durability for repeated use while maintaining effective grinding action. Key attributes Material: soft rubber for safer, flexible operation. Function: grinding and cleaning tooth surfaces. Design: outer concave shape to enhance contact and cleaning effectiveness. Performance: consistent contact, improved debris control, gentle on surfaces. Use scenarios Routine surface cleaning: remove light deposits and smooth surfaces during routine tooth maintenance tasks. Targeted grinding: refine small rough spots or edges where a flexible grinding surface improves control. Final finishing: access curved or irregular surfaces to deliver an even finish and remove residual debris. This product is intended to provide a safer, more adaptable rubber grinding surface with an outer concave design that improves contact and cleaning effectiveness for tooth-related grinding and cleaning tasks.
