Abstract: Tooth transposition is the positional interchange of two adjacent teeth or the development or eruption of a tooth in a position occupied normally by a non-adjacent tooth. It has a reported incidence of 0.4% of the population and is more common in females. Canine–premolar transposition is the most common presentation, occurring more frequently in the maxilla.2 A 17-year-old female presented with an unerupted left maxillary canine in complete transposition with the maxillary left first premolar. Orthodontic treatment to correct the malocclusion and the transposition was complicated by gingival recession, which in turn was treated with corrective periodontal surgery.

Clinical relevance: This case report demonstrates the risk of localized gingival recession in the orthodontic management of canine–premolar transposition cases, even when opting for a less hazardous treatment plan. Most importantly, it highlights the importance of an interdisciplinary approach to patient care.
