A prosthetic tooth having a bridge clasping arm and a clasping structure is disclosed. The prosthetic tooth includes a prosthetic tooth and at least one bridge clasping arm. The bridge clasping arm is connected to one side of the prosthetic tooth and includes a first clasping portion, which is formed on an inside surface of the bridge clasping arm. A second clasping portion is provided on an adjacent tooth, which corresponds to the bridge clasping arm. When the bridge clasping arm is positioned on the adjacent tooth, the first clasping portion and the second clasping portion engage each other for clasping. The present inventions uses the bridge clasping arm for connection with an adjacent tooth in order to improve the capability of the prosthetic tooth for bearing forces acting thereon.
