PCT No. PCT/DK84/00059 Sec. 371 Date Feb. 28, 1985 Sec. 102(e) Date Feb. 28, 1985 PCT Filed Jun. 25, 1984 PCT Pub. No. WO85/00101 PCT Pub. Date Jan. 17, 1985.A toothpick made from plastic for manual removal of film on teeth and for stimulation of the gum is upwardly curved at its pointed end portion (1) to prevent the pointed end from penetrating the gum, which may often occur, especially in case of negative papillae. Furthermore an underlying, longitudinal notch (3) is provided above the back portion (4), which allows the toothpick to be compressed in its transverse direction, and which moreover allows room for the gum in case of normal as well as damaged papillae. Furthermore, transverse flaps (5) on both sides of the toothpick are provided, in order that these may strike the tooth surfaces efficiently, even where particles from repair work on teeth may remain and fill the spaces between the teeth. To facilitate easy orientation and operation, the toothpick has been provided with an upwardly projecting plate (6) towards its rear portion. |
