Decompression could be used as a conservative treatment approach for the management of large radicular cysts in children to have satisfactory healing and minimum damage to adjacent vital structures, simultaneously allowing the eruption of succedaneous tooth. This paper discusses the management of a large radicular cyst in a 12 year old, causing displacement of the mandibular canal and developing tooth germ using decompression that resulted in bony healing and spontaneous eruption of displaced succedaneous premolar, with a periodic follow-up for 40 months. Although decompression is a well-known approach, the present case with long-term follow-up emphasizes the potential of spontaneous healing in pediatric radicular cyst cases restoring the anatomy to normal without any functional impairment.
