Ugly Duckling Stage

A stage of dental development in children that precedes the eruption of permanent canines, so called because the lateral incisors may be tipped laterally due to crowding by the unerupted canine crowns
This tipping may cause spacing of the incisor crowns despite crowding of the roots. The condition is often temporary and does not preclude normal dentition. The name is directly borrowed from Hans Christian Andersen’s allegorical fable of the same name
