Abstract: | The occurrence of supernumerary teeth is a relatively uncommon dental anomaly. The aetiology is not clear. Supernumerary teeth have frequently been observed as solitary teeth and impacted in the maxillary arch. This case report describes the rare presence of bilateral maxillary fourth molars and a supernumerary tooth in the maxillary canine region. On the left side, the third molar was extracted first, allowing the fourth molar to move into a more favourable position for later extraction. Two-year postoperative radiography confirmed that the supernumerary tooth had migrated occlusally and mesially permitting a safer extraction procedure. |
