What is a supernumerary tooth?

Where are supernumerary teeth found?
The most common form is a mesiodens, which forms between the two maxillary central incisors ( Hyun et al., 2009 ), but supernumerary teeth can also be found in the premolar and at the posterior end of the dentition ( Hyun et al., 2008; Kawashita and Saito, 2010 ).
Where is hyperdontia found?
Hyperdontia normally occurs in the anterior maxillary dentition. Supernumerary teeth are classified according to their location as “normotrophic,” occurring within the dental alveolus, or “heterotophic” when they are located in the surrounding jaw, sinuses, or nasal cavity ( Ortner, 2003 ). However, not all heterotrophic teeth are supernumerary. The shape of an additional tooth can vary from a normal morphology, mimicking the original tooth (supplement or eumorphic tooth), to an atypical morphology ( Schuurs, 2013 ). These atypical teeth may display extra cusps (tuberculated) or be more irregular due to tumor-like excessive growth of the dental tissue (odontomatous). Peg-shaped teeth, or mesiodens, are the most common and tend to be located between the central and lateral incisors. Their presence can cause malocclusion, infection, and cyst formation ( Rosenzweig and Garbarski, 1965 ). Hyperdontia is rare in the deciduous dentition, making up 0.5%–1% of cases, whereas up to 3% occur in the permanent teeth ( Fig. 4.11 ). The incidence of supernumerary teeth in modern populations has been estimated at 1.9% ( Suzuki et al., 1995 ), but populations in Alaska have been reported to have a 10% occurrence ( Schuurs, 2013 ). Lopes et al. (1991) recorded an incidence of supernumerary teeth in 16% of individuals with cleft palate.

Can a supernumerary be inverted?
If the supernumerary is conical and is not inverted, there is a reasonable chance that it will erupt, at which time it should be removed (Fig. 36.22 ).
When to remove a supernumerary?
Before 10 years of age: if the unerupted central incisor is correctly aligned the treatment of choice is to remove the supernumerary surgically and allow normal eruption of the permanent tooth. Gingival exposure may be required later because of surgical scar formation that can inhibit final soft-tissue emergence. Some authorities recommend the simultaneous removal of primary canines to counteract this tendency. Inverted supernumeraries can be removed less traumatically if surgery is performed early, however, this needs to be done with caution to avoid damage to the adjacent tooth germs.

Can supernumerary teeth fuse to normal teeth?
