PROBLEM TO BE SOLVED: To provide box-shaped tooth washing equipment capable of washing teeth at a short time and allowing a user to easily use the equipment.SOLUTION: The tooth washing equipment comprises: a front face part 7 a back face part 9 and a coupling part 11 for coupling the front face part 7 and the back face part 9. A recess 19 is formed between an inner face 13 of the front face part and an inner face 15 of the back face part. On one or both of the inner face 13 of the front face part and the inner face 15 of the back face part, a tooth washing action part 21 is provided. When a main body part 3 is moved along a tooth row in a state in which the recess 19 is made to cover the tooth row T, the tooth washing action part 21 contacts both or one of front faces and back faces of teeth, for generating a tooth washing action.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】使用者が容易に且つ短時間で歯の洗浄を行うことができる箱形の歯洗浄装置を提供する。【解決手段】前面部7と、背面部9と、上記前面部7と背面部9とを結合する結合部11とを備える。前面部の内面13と背面部の内面15との間に凹部19が形成される。前面部の内面13と背面部の内面15の両方または一方に歯洗浄作用部21が設けられ、凹部19を歯列Tに被せた状態で歯列に沿って本体部3を移動させたときに、歯洗浄作用部21が歯の前面と歯の背面の両方または一方に接触して歯の洗浄作用を生じる。【選択図】図1
