The main principle is protecting the developing permanent tooth when a luxation injury occurs to a primary tooth. In young children, the tooth beneath the displaced primary tooth is still forming, so aggressive repositioning or reimplantation can easily damage the permanent tooth germ. The safest and most common approach is to observe and monitor the situation, letting the primary tooth heal or erupt without intervention. Extraction is reserved for situations where the displaced primary tooth poses a clear risk to the permanent successor or when the injury is so severe that preserving the tooth would do more harm than good. Immediate endodontic treatment of the primary tooth isn’t routinely indicated for luxation, since the primary tooth often lacks a long-term favorable prognosis after such trauma and endodontic therapy doesn’t address the risk to the developing successor. Reimplantation after temporary storage is generally avoided in primary teeth because it can damage the underlying permanent tooth germ. Continuous follow-up is essential to detect any eruption disturbances or pathology in the permanent successor.
