Skeletal discrepancy: Dental skeletal discrepancy can be a cause behind gap teeth. If the upper jaw grows more than the lower jaw, teeth on the upper jaw will have more space to cover thus leaving gaps between them. 5.
In some individuals, the additional teeth can erupt far from the dental arch, within the maxillary sinus. The extra teeth may also migrate to a different location after development. [1] In some cases, supernumerary teeth can lead to the formation of cysts. Crowding is also frequently seen in people with hyperdontia. [2]
Reconstructive surgery is usually required in order to increase cranial space, correct tear duct stenosis, and/or correct ptosis of the eyelids in order to prevent amblyopia (lazy eye). [ 2 ] Midfacial surgery may also be required during early childhood to correct respiratory problems, dental malocclusion , and swallowing difficulties.

Orthodontic space closure [69] [80] is a way of using orthodontics in order to close spaces in the mouth where the teeth are missing. The ideal age for definitive orthodontic treatment is early adolescence but it is important to consider the patient's age, severity of hypodontia, patient expectations and their commitment to treatment.
