Fibrous dysplasia is a developmental tumor-like condition that is characterized by replacement of normal bone by an excessive proliferation of cellular fibrous connective tissue intermixed with irregular bony trabeculae. Craniofacial lesions may cause facial pain, headache, cranial asymmetry, facial deformity, tooth displacement and visual or auditory impairment. In this case, a 2-year-9-month old boy who was diagnosed as the fibrous dysplasia showed delayed eruption on affected area. Teeth of left lateral dentition group have erupted completely but teeth of right lateral dentition group are erupting slowly. Eruption and maturation of affected teeth are in progress, so continuous observation is required presently. If the eruption state stops, surgical opening or forced eruption of the impacted teeth will be considered.
