Abstract
This article presents a case of temporary right-sided numbness of the lower lip during orthodontic treatment to upright an impacted lower right second molar (LR7) in a 15-year-old male. Following cone beam computed tomography (CBCT) this was revealed to be a result of deficient bone between the roots of LR7 and close intimacy to the mandibular canal. Traction to LR7 was discontinued and the patient's orthodontic treatment was completed uneventfully, with full recovery of normal sensation in the lower lip. CPD/Clinical Relevance: Sensory nerve symptoms initiated by orthodontic treatment are rare, and the presentations, diagnostic tools, management and outcomes of these cases have been reviewed to devise and recommend an appropriate management plan for the treating clinician.
