The Cryer root elevator, angled, size 7 is a specialized dental instrument designed to remove retained tooth roots and root fragments.

It operates on the principle of a lever. The instrument's sharp, triangular tip is inserted into the periodontal ligament space between the root and the bone. By applying a controlled rotational force, the elevator uses the alveolar bone as a fulcrum to multiply the force, effectively luxating and lifting the root out of its socket. As the name implies, a size 7 Cryer elevator has a working tip that is 7 mm wide.
