PROBLEM TO BE SOLVED: To provide a tooth protection device that is used by attaching to teeth in the tracheal intubation to children, the device that prevents the damage of upper jaw front teeth by a laryngoscope and can keep a stable fitted state, and thereby is suitable for the situation of children's mouth and teeth.SOLUTION: A teeth protection device is constituted of: a device body 1 comprising the U-shaped bottom 13 with a recessed cross section so as to be fittable to an upper dental arch, and front and back walls; and a reinforcing part 2 projected to a central portion of the bottom. The teeth protection device includes a notch 14 in a region across the upper lip frenulum of a surface side wall 11. A backside wall 12 is constituted by being set only in the region corresponding to the molar of both flanks and being not provided in the region corresponding to the front teeth. Also, the surface side wall is configured such that the front teeth side of the central part is formed higher than the molar side of both flanks, and the central part is inclined inside by the angle of 55° or more and 65°or less to the bottom surface. Furthermore, the notch is set to the depth where the deepest part may coincide with the bottom inner surface of the device body or becomes 5 mm or less from the bottom surface.SELECTED DRAWING: Figure 1 【課題】小児への気管挿管のさい、歯牙に覆着して用いる歯牙保護デバイスにあって、喉頭鏡による上顎前歯の損傷を防止すると共に、安定した嵌着状態を保つことができる、小児の口腔や歯牙の状況に好適なデバイスを提供する。【解決手段】上顎歯列弓に嵌着可能に、Ｕ字形状で断面を凹型とした底部１３及び表裏の壁部からなるデバイス本体１と、前記底部の中央部分に突設する補強部２より構成し、表側壁部１１の上唇小帯を挟む部位に切り欠け部１４を備えた歯牙保護デバイスにおいて、裏側壁部１２を両翼の奥歯にあたる部位にのみ設定し、前歯にあたる部位には設けない構成とした。また、表側壁部は両翼の奥歯側より中央部の前歯側を高く形成し、該中央部は、底面に対し５５°以上、６５°以下の角度で内側に傾斜させた。更に、前記切り欠け部は、最深部が前記デバイス本体の底部内面と一致するか、底面から５ｍｍ以下となる深さに設定した。【選択図】 図１
