ABSTRACT Multiple supernumerary teeth are one of the most common developmental anomalies in humans. They could be associated with prolonged retention of deciduous teeth, displacement or rotation of the adjacent teeth, crowding, aberrations in the root morphology (dilacerations), and failure in eruption or impaction of the succedaneous teeth. This article highlights 2 cases of non-syndromic mandibular twin supernumerary teeth in young female clients with a chief complaint of spacing between the teeth and over-retained deciduous teeth. A diligent clinical and radiographic monitoring is warranted considering the early innocuous effects and delayed adverse effects of this condition
