K07: Dentofacial anomalies [including malocclusion]

K07.4: Malocclusion, unspecified

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.

Changes to, or incorrect positioning of, the jaw bones or the teeth may be the reason why the two rows of teeth are not properly aligned. It may even be impossible for the teeth to bite together.
