Supernumerary teeth may be detected by taking two different dental X-rays at different angles. Examples of this may be an intra-oral X-ray (one that is taken inside the mouth) and a panoramic radiograph. However, these X-rays are 2D and therefore do not accurately portray the 3D view of the teeth. Types Dental stone model showing mesiodens and accessory tooth behind right central incisor Supernumerary teeth can be classified by shape and by position. The shapes include the following: * Supplemental (where the tooth has a normal shape for the teeth in that series); * Tuberculate (also called barrel shaped); * Conical (also called peg shaped); * Compound odontoma (multiple small tooth-like forms); * Complex odontoma (a disorganized mass of dental tissue) When classified by position, a supernumerary tooth may be referred to as a mesiodens, a paramolar, or a distomolar. Occasionally, these teeth do not erupt into the oral cavity but manifest as a malocclusion. The most common supernumerary tooth is a mesiodens, which is a malformed, peg-like tooth that occurs between the maxillary central incisors. Fourth and fifth molars that form behind the third molars are another kind of supernumerary teeth.
