Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including malposition and malformation of the tooth bud, dentomaxillofacial disharmony, tumors, and cysts. This case was a 6-year-old female with complete left cleft lip/palate. A maxillary right second deciduous molar impacting at a high level approximate to the maxillary sinus was noted on the initial visit. To prevent surgical trauma to the surrounding tissue and succedaneous teeth, regular follow-up with radiographic examination was taken every 2 years. After a 7-year long-term follow-up, the impacted second primary molar in the right maxillary sinus had almost completely been resorbed with only about 10% of the original structure left. To the present, the resorption of the impacted deciduous molar seemed to have continued with no major pathological changes. Periodic radiographic examination is strongly advised until the total resorption process is completed.
