Facial nerve palsy is a rare but known complication of dental local anaesthesia and may be underreported. We describe a case of a transient facial nerve palsy following the administration of an inferior alveolar nerve block and discuss the immediate practical management. Knowing the likely transient nature of this complication means the patient can be reassured and unnecessary referral avoided. While the blink reflex is inhibited, steps are needed in order to protect the cornea and prevent secondary infection and scarring. © BMJ Publishing Group Limited 2020. No commercial re-use.
