What it means
An abnormal conical form of the teeth, that is, a tooth whose sides converge or taper together incisally.
A conical shape of a tooth occurs in incisors and canines only. Conical teeth may occur isolated or associated with other dental anomalies, such as hypodontia and oligodontia; this should be assessed and coded separately.
