Central giant cell granuloma is a relatively uncommon benign bony lesion of a variably aggressive nature. This paper presents the case of a 7-year-old boy with central giant cell granuloma in the anterior mandible. In children with mixed dentition, a pathologic lesion could be the underlying cause of regular tooth mobility and exfoliation of primary teeth and can easily be overlooked, especially in cases that are not accompanied by an obvious bony expansion. The clinician needs to be aware of possible oral pathology when tooth mobility and displacement are present, and central giant cell granuloma should be considered in the differential diagnosis for children with maligned and mobile teeth.
