Dental malocclusion. Close-up of the mouth of a patient with a dental malocclusion affecting the upper right canine (upper left). A malocclusion is misalignment between the teeth of the upper and lower jaws as they close. It may be an inherited condition, or the upper and lower jaws may be different sizes. Crowding of the teeth in the mouth may also cause the condition. Braces may be used to correct the position of the teeth. Extraction of some teeth may also be required if there is overcrowding. In extreme cases surgery to lengthen or shorten the jawbones may be necessary. Here, the upper canine is strongly protruding from the dental arch.
