What it means

A tooth crown with its mesial and distal sides converging or tapering toward the incisal edge causing severe reduction of mesiodistal diameter

A peg shape appearance of a tooth occurs in lateral incisors only. A peg-shaped tooth is a microdont tooth and may occur isolated or associated with other dental anomalies, such as hypodontia and oligodontia; this should be assessed and coded separately.
