Abstract
Supernumerary teeth are one of the routinely encountered developmental disturbances representing one or more extra teeth in the jaws. These may resemble the teeth of the group to which it belongs, i.e., molars, premolars, or incisors, or it may bear little or no resemblance. Based on the morphologic appearance, it is classified as supplemental teeth or rudimentary teeth. The supplemental teeth are those that resemble the teeth to which it is associated and rudimentary teeth are those that do not resemble the teeth. Supplemental teeth, most of the times, are associated with syndromes and they can also be present in the absence of systemic pathology. Literature reveals predilection of the presence of supplemental premolars of 2:1 in males.This is the case report of a 14-year-old male who presented with multiple unerupted bilateral supplemental premolars on both the arches.How to cite this articleSatish V, Panda S, Maganur P, Ahmed A.

Highlights
Supernumerary teeth or hyperdontia is a mammalian developmental abnormality, which is characterized by the presence of extra teeth
Around 90 to 98% of supernumerary teeth occur in the maxilla, and 90% of these are restricted to the premaxilla.[2]
This developmental anomaly can occur either in the maxilla or in the mandible.[3]. They have frequently been seen in association with syndromes, such as Gardner’s syndrome, cleidocranial dysplasia, trichorhinophalangeal syndrome, and cleft of the lip and palate. They can be associated in the absence of systemic pathology.[3]
Summary
Supernumerary teeth or hyperdontia is a mammalian developmental abnormality, which is characterized by the presence of extra teeth. Those teeth that resemble the teeth of the group to which it belongs, i.e., molars, premolars, or incisors, are called supplemental teeth, and rudimentary teeth are those teeth that bear little or does not resemble the teeth with which it is associated This developmental anomaly can occur either in the maxilla or in the mandible.[3] They have frequently been seen in association with syndromes, such as Gardner’s syndrome, cleidocranial dysplasia, trichorhinophalangeal syndrome, and cleft of the lip and palate. The supernumerary teeth have been observed in the gingiva, soft palate, nasal cavity, maxillary sinus, sphenomaxillary fissure, ophthalmic conchae, maxillary tuberosity, incisive suture, and between the orbit and the brain.[16]
