Abstract: Second premolars are one of the last successional teeth to erupt in the maxillary and mandibular arches. Early loss of primary teeth or first permanent molars can lead to disrupted eruption of these teeth. This article gives an overview of the possible aetiology and treatment of the aberrant second premolar.

Clinical relevance: Awareness of the possible sequelae of unerupted second premolars is important in diagnosis and treatment planning.
