A tooth and adaptor assembly is provided for a dipper bucket. The assembly comprises an adaptor having a rear portion for attaching to the dipper bucket, a tooth capable of releasable attachment to the adaptor and a retainer pin for securing the tooth to the adaptor. The adaptor further comprises a tapering intermediate portion that narrows to a rectangular front portion. The adaptor further comprises a planar surface on a portion of its intermediate portion and a groove that traverses the planar surface, the groove perpendicular to the horizontal longitudinal axis of the adaptor. The tooth has a tip at its front end for digging and a socket at its rear end configured to receive the front and intermediate portions of the adaptor. An opening on the rear end of the tooth aligns with the groove when the tooth is coupled to the adaptor to define a passageway that terminates within the socket of the tooth. The retainer pin is adapted to be inserted into the passageway to secure the tooth to the adaptor and complete the assembly.
