To provide a dental tool which can be used for removing a metal core and has a wide range of application. SOLUTION: The dental tool 10 includes a rod portion 14 having both ends, a flat portion 16 connected to one end of the rod portion 14 and having a pair of principal faces 16s, 16t, a grip connected to the other end of the rod portion 14 Section 12. The flat portion 16 is recessed from the outer peripheral edge 16 k of the flat portion 16 and has a recess 18 penetrating between the main surfaces 16 s and 16 t of the flat portion 16 and a pair of projections 18 p and 18 q are formed on both sides of the recess 18 . The flat portion 16 of the two dental tools 10 is inserted into the groove formed between the core of the metal core and the tooth and the grip portion 12 is rotated in a state where the post of the metal core is disposed between the concave portions 18, One of the pair of protrusions 18 p and 18 q is pressed against the teeth and the other is pressed against the core of the metal core to widen the groove so that the metal core can be removed from the teeth. BACKGROUND OF THE INVENTION【課題】メタルコアの除去に使用することができ、適用範囲が広い歯科用ツールを提供する。【解決手段】歯科用ツール10は、両端を有する棒部14と、棒部14の一方端に繋がり、一対の主面16s,16tを有する平坦部16と、棒部14の他方端に繋がる把持部12と、を備える。平坦部16は、平坦部16の外周縁16kから後退し、かつ、平坦部16の主面16s,16t間を貫通する凹部18が形成され、凹部18の両側に一対の突起部18p,18qを有している。メタルコアのコアと歯の間に形成された溝に、2本の歯科用ツール10の平坦部16を差し込み、凹部18の間にメタルコアのポストが配置されている状態で把持部12を回転し、一対の突起部18p,18qのうち一方を歯に押し当て、他方をメタルコアのコアに押し当てながら溝を広げて、メタルコアを歯から外すことができるように構成されている。【選択図】図1
