Hyperdontia is the development of extraneous teeth. It occurs in 1–3% of Caucasians and is more frequent in Asians. [65] About 86% of these cases involve a single extra tooth in the mouth, most commonly found in the maxilla, where the incisors are located. [66] Hyperdontia is believed to be associated with an excess of dental lamina.

Having this condition means patients have supernumerary teeth - additional teeth other than 20 primary teeth in children and 32 permanent teeth in adults. The reasons for this condition could be any of the following: Dichotomy (division) of tooth buds.
Additionally, the evolution and reduction in the jaw has left little room for the third molar, or wisdom tooth, to form. As a result, many individuals choose to remove them through surgery. One of the defining features among Homo sapiens is the presence of a chin. A protruding chin was absent in archaic hominids, as well as Neanderthals ...
