A tooth for a digging bucket of an excavator has a wedgelike profile formed by an end face and two surfaces extending at an angle with respect to each other, one of which is undulated with at least two convex portions conjugated by a concave portion. The profile of the undulated surface in the concave portion is in the form of brachistochrone. A groove is made in the end face of the tooth to extend widthwise of the tooth.
