The true prevalence of developmental dental disorders in horses is unknown, but from a clinical perspective, dental dysplasia of varying degrees of severity appears to be far more common than developmental abnormalities of tooth numbers. The latter includes the presence of increased numbers of teeth (supernumerary teeth), which in turn appears more prevalent than reduced numbers of teeth (hypodontia or anodontia). This clinical commentary briefly reviews all three types of developmental dental disorders from a clinical viewpoint.
