The invention circulation of the gum at the same time minimizing the enamel wear of possible to prevent the resulting damage to the teeth and gums when configured by a synthetic resin foam Chimoio parts of the toothbrush people to brushing and produced well due to brushing on the cervical portion of the tooth irritation to have the gum massaging effect to maintain the health, possible to reduce the convenience and cost in to produce the toothbrush can also be further extended the life span in a more simple form of Chimoio unlike toothbrush and consisting Chimoio of a number of strands , and it wishes to provide a toothbrush one so old toothbrush and can otherwise be Chimoio got a pat on the surface and the wide surface of the tooth to closely removed more effectively plaque by the contact without maximizes than a cleaning and whitening of teeth to. That is, the present invention is the handle portion 2 and Chimoio unit in a normal toothbrush (1) made of a (3), and the coupling hole (5) formed in the Chimoio part (3), said coupling hole (5) coupling plate which is forced-fit enables exchange 6 and, with the coupling plate (6) at a matrix (4) which is secured to the upper, the value matrix (4) is made of synthetic resin foam (foam), the upper surface portion, uneven surface (4a) is formed, the coupling hole 5 and the binding plate assembly has engaged with the engaging grooves 8 the projections (7) corresponding side of (6) is formed, value matrix (4) is soft internal a core member configured to form synthetic resin (4-1), and the external matrix is ​​made of the soft synthetic resin foam (4-1) of the hard synthetic resin so as to surround the first wrap form (4-2), or the value 4, and a soft synthetic resin foam produced in (4-1), the core material may be produced as a synthetic resin foam (4-2) of the internal rigid intergranular plurality, Chimoio body 4 is simply a soft synthetic resin foam itself (4-1) alone will be produced that can form a synthetic resin alone (4-2) of the light, the inside of the value matrix (4) may be one or more intergranular plate spring 9 naejineun coil spring 10. Such a toothbrush (1) provided by the present invention value matrix (4) to a soft or by configuration enabling a refill to selectively utilize a synthetic resin form a rigid, unlike the toothbrush and with a common Chimoio soft synthetic resin foam consists prevent tooth and gum damage when brushing your teeth, and can also further extend the life of the toothbrush, it is because there is no Chimoio numerous strands having a common toothbrush can simplify the production of toothbrushes, toothbrush manufacturing processes and reduce costs that value will be in contact with the tooth surface with a matrix to maximize the effect than the teeth cleaning effect. Toothbrush, Chimoio wealth, value matrix, synthetic resin foam, springs, combined plates, the engaging projection
