A tooth assembly for an excavating machine includes an adapter having first and second surfaces and first and second sides. The first surface of the adapter is generally tapered and converges toward a first end of the adapter. A tooth point is coupled with the adapter at the first end of the adapter, and the tooth point has a contact edge opposite the first end of the adapter. The tooth point also includes first and second sides, the first side having a slot adapted to receive a non-rotation ridge of a retainer pin to prevent rotation of the retainer pin with respect to the tooth point. A second end of the adapter is adapted to be removably coupled with a tooth horn. The tooth assembly further includes a central portion extending generally from the first side of the adapter to the second side, the central portion defining a central bore. In accordance with a particular embodiment of the present invention, a retainer pin with a non-rotation ridge may be coupled with the central portion of the tooth assemble at least partially within the central bore.
