Correct answer: A — Reposition under local anaesthesia using controlled force, flexible splint for 4 weeks

Lateral luxation involves displacement of the tooth (usually palatally or labially) with fracture of the alveolar socket wall. The tooth is locked in its displaced position (not mobile). Management involves repositioning under local anaesthesia using digital pressure (controlled force to disengage the locked apex), followed by a flexible splint for 4 weeks (IADT guidelines). Pulp vitality monitoring is essential; necrosis occurs in a significant proportion of laterally luxated permanent teeth, especially those with closed apices.
