Fusion is a developmental anomaly which results in the union of two adjcent teeth. Fusion of premolars in the permanent dentition is a rare phenomenon and fusion to a supplemental tooth could be considered even rarer. Treatment of such a complication would be to observe the condition, extraction of the fused premolar to gain space for the canine followed by orthodontic treatment, hemi-section of the fused tooth or surgical removal of the canine. Any decision should be made after careful evaluation of the This case report describes an unusual case of a supplemental premolar fused to the upper first premolar in a 12 year old patient resulting in impaction of the canine, poor aesthetics and a cross bite. Following consultation with the orthodontist the fused upper right first premolar was sectioned and the mesial portion of the fused tooth removed. The remaining tooth segement was endodontically treated. This provided adequate space for the erupting canine which only required adjunctive orthodontic allignment.
