Trigeminal neuralgia is a chronic pain condition affecting one or more distributions of the trigeminal nerve. Patients with this condition experience short, sharp, shooting pain attacks, which can progress to longer, more frequent durations. The pain is often difficult to control. We report of a man who was admitted with severe neuralgia of the third division of the trigeminal nerve. Talking and any oral intake triggered a severe agonising pain. The latter made the regular oral intake of analgesia challenging. The pain was temporarily controlled with frequent local anaesthesia (LA). Dental core trainees were performing regular inferior alveolar nerve blocks which significantly improved patients’ condition allowing him to communicate and have oral intake. Subsequently, a catheter was placed allowing for a continuous anaesthesia. The connecting tube of the cannula was then used by nursing staff to administer LA providing pain relief without the need of repeated intraoral injections.
