A young child sustains an intrusion injury to a primary tooth; there is no pain and the degree of intrusion is mild. The recommended management is to:

Correct answer: A. Monitor — allow spontaneous re-eruption

• A. Correct. Mildly intruded primary teeth (and many immature/intruded teeth) are typically left to re-erupt spontaneously with monitoring, provided the developing permanent tooth bud is not impinged.
• B. Immediate extraction is not indicated for a mild intrusion without complications.
• C. Surgical repositioning/splinting is not the first choice for a mild primary intrusion.
• D. Root canal therapy is not indicated unless pulp necrosis later develops.
