K07: Dentofacial anomalies [including malocclusion]

K07.5: Dentofacial functional abnormalities

The top row of teeth consists of all the teeth in the upper jaw. The bottom row of teeth consists of all the teeth in the lower jaw. The two rows of teeth usually rest on each other in a particular way when you bite.

Certain habits can change the alignment of the two rows of teeth with each other. These include sucking one's fingers or lips, for example. Such habits also include continuously breathing through one's mouth or some change in how one swallows.
