A kit, a tool, and a method of use for securely retaining a dental restoration on a prepared tooth stub having a top surface and a bore extending therein. The kit comprises plural dental posts of varying sizes and a tool. Each dental post includes an enlarged head and a shank. The shank is an elongated member having a first longitudinal axis arranged to be fixedly secured within the stub's bore so that the post's enlarged head extends beyond the stub's top surface. The enlarged head has plural through passageways, e.g., a coronal passageway, and a transverse passageway that communicate with one another for receipt of a setable securement medium which flows therein and about the surface of the head to secure the dental restoration to the post. The tool includes a handle portion and an opposed pair of free end tips. Each free end tip is shaped to be inserted and frictionally received within the transverse passageway of selected ones of the dental posts of the kit to releasably mount the selected dental post on the tool. The tool's handle portion is arranged to be grasped in the hand of a user to carry the post to the prepared stub and to insert its shank into the bore so that its enlarged head is located above the top surface of the tooth stub. The tool can then be manipulated to release the frictional engagement between its free end tip and the dental post to enable the tool to be removed, leaving the dental post in place. The dental restoration can then be secured to the post's enlarged head.
