# Missing teeth

Teeth may be truly absent as a result of an inherited abnormality or as a result of disturbances in the formation of the tooth during the initial stages of development. A complete absence of teeth is known as '''''anodontia''''', which is very rarely seen in dogs. '''''Hypodontia''''', the absence of a few teeth, is relatively common in dogs and is seen in many breeds. The premolars appear to be the most commonly affected teeth. In people, ''anodontia'' has been associated with ectodermal dysplasia. This may be similar in hairless breeds which often present with missing or malformed teeth. An unerupted tooth may be unerupted due to the presence of thick fibrous gingival tissue. The teeth most commonly affected are the first premolars. A [[Intra-Oral Radiography - Small Animal|radiograph]] should be taken to confirm the presence of the tooth. If a tooth is present a procedure called an '''operculectomy''' (excision of gingival tissue) can be performed to allow crown exposure and further eruption of the tooth.

An '''impacted tooth''' is a tooth that has failed to erupt, as the path of eruption has been obstructed by another tooth or some other physical barrier. <font color="red">(pic15impacted)</font color> Occasionally it may be due to an abnormal eruption path secondary to unusual orientation of the tooth bud. This can be a result of malformation of the tooth bud or as a result of trauma to the developing tooth bud.

A '''[[Dentigerous Cyst|dentigerous cyst]]''' is a developmental odontogenic cyst and can exhibit as missing teeth.

Although not strictly supernumerary teeth, [[Persistent Deciduous Teeth|persistent deciduous teeth]] may also cause problems. Persistent deciduous teeth is an inherited condition in certain breeds and results in the development of a [[Dental Malocclusion|malocclusion]] as well as plaque retention and resulting [[periodontitis]].
