When the inferior alveolar nerve is blocked at the level of the mandibular foramen, the lingual nerve, another branch of the mandibular nerve, may also be blocked. The lingual nerve provides sensory innervation to the rostral two‐thirds of the tongue. This may result in the horse biting its tongue inadvertently, especially if the block has been performed bilaterally.

There is a published report of three horses with self‐inflicted lingual trauma secondary to extra‐oral inferior alveolar nerve block, one of which was a bilateral block [102]. In these cases, a total volume of 15 or 20 mL of mepivacaine per site was used. A recent retrospective study of complications related to dental blocks also reports 2 cases of self‐inflicted lingual trauma, both secondary to maxillary nerve block, 24 hours following unilateral or bilateral blocks [1].
