Hyperdontia is a condition in which too many extra teeth grow in the mouth. This condition is also referred to as supernumerary teeth. These teeth can grow anywhere in the curved areas or dental arches where the teeth attaches to the jaw. Development of supernumerary teeth might be due to several hereditary conditions such as Gardner’s syndrome, Ehlers-Danlos syndrome, cleidocranial dysplasia, etc. Supernumerary teeth lead to delayed eruption of adjacent teeth and cause significant crowding. In some cases, this can lead to the development of cysts or tumors. [Image used under Creative Commons License from Wikimedia]
Dental crowding also called malocclusion is a hereditary condition that is characterized by an insufficient amount of space for all the teeth to properly fit within the mouth. Losing your primary teeth too early or an improper growth of teeth can also cause teeth crowding.
