Surgical removal of the supernumerary teeth is indicated in case of delayed eruption
, displacement of the adjacent tooth, cystic lesion, and resorption of the adjacent tooth, but if the risks of surgery are more than benefits, the teeth may be left in situ and monitored regularly .
In children with a family history of delayed eruption
, pulling the baby teeth doesn't speed up the eruption of the permanent teeth.

In present cases report, the fused primary incisors lead to delayed eruption
of its successor.
Impacted teeth are those with a delayed eruption
time or that are not expected to erupt completely based on clinical and radiographic assessment.4 In impacted teeth, root development might have finished, but un- aided eruption is not expected to occur.
of permanent maxillary incisors has numerous causes such as supernumerary teeth, tooth malformation or dilacerations, tooth agenesis, cysts or other pathological obstructions in the eruptive path, retained primary incisor that has become ankylosed, presence of a dense mucoperiosteum or submucosa that acts as a physical barrier to eruption, lack of space or in association with certain syndromes.
The oral manifestations include conical or peg shaped teeth, hypodontia or complete anodontia of both the deciduous and the permanent dentition with malformation of any teeth that may be present, generalized spacing, underdeveloped alveolar ridges and delayed eruption
of permanent teeth.
