The patient was a 9-year-old Iranian boy. The left lateral maxillary tooth was found during the oral examination. In the radiographic presentations, the fused teeth showed separate roots, pulpal chambers, and separate root canals. Delayed eruption of the first and second maxillary permanent incisors was experienced due to the presence of an extra impacted tooth. In the management of this condition, both the deciduous fused teeth and extra impacted teeth were removed, and an appointment was scheduled for three months to check for spontaneous tooth eruption.
