Interdental wedge comprises a combination of a wedge body and a compressible base (3) having an edge (4) protruding on both sides of the wedge body. Preferred Features: The base is made of a material which changes from a non-compressible state to a compressible state on the application of force. Further compression increases super proportionally to compression. The base is made of a thermoplastic elastomer provided with a light-scattering substance and the wedge body is made of a light-impermeable plastic. |
