Background: There are a number of reported complications of inferior alveolar nerve (IAN) block administration. One of these complications is that of neurosensory disturbance, which may be attributed to the block technique or type of local anaesthetic used. The authors present a case of an unusual and largely unreported complication of maxillary branch paraesthesia following an articaine IAN block. Case description: A patient developed neurosensory disturbance of the facial nerve, maxillary and mandibular divisions of the trigeminal nerve following the administration of an IAN block for restorative dentistry. He returned 3 days after the IAN block with anaesthesia of both upper and lower left lip, cheek, tongue and loss of taste on the ipsilateral side. Neurosensory testing a year post‐injury still showed neurosensory impairment in the maxillary and mandibular distributions of the trigeminal nerve. Discussion: The mechanism of nerve injury post‐IAN administration is explored and the relevance of articaine local anaesthetic solution is considered.
