Abstract:
Supernumerary teeth develop in addition to the normal dentition and are a therapeutic challenge for pedodontists, orthodontists and oral surgeons alike. Therefore, interdisciplinary treatment concepts are needed for the benefit of the patient. In the present, two-parted literature review on supernumerary teeth, current classification, associated complications, diagnostic steps and different therapeutic approches are presented and discussed. Supernumerary teeth are diagnosed in the primary and permanent dentition. Supernumerary incisors, canines, premolars, and molars, as well as distomolars and mesiodentes can be seen according to the location of the supernumerary teeth. Furthermore, based on the morphology of the supernumeraries four different types can be differentiated: conical, tuberculate, supplemental, and odontoma. Supernumerary teeth often remain asymptomatic, and are only diagnosed incidentally during a routine dental visit on radiographs (often intraoral). Nevertheless, various complications have been reported in the literature for supernumerary teeth such as disturbed eruption, malpositioning/rotation, root resorption of neighbouring teeth, and development of dentigerous cysts in impacted supernumeraries. Root resorption of neighbouring teeth can be radiographically diagnosed in up to 22.8% of the cases.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
