The buccal nerve is a sensory nerve that innervates the cheek and the buccal mucosa. There are several synonyms for this nerve, which include the buccinator nerve, the buccal branch of the facial nerve, and the buccal branch of the mandibular nerve. The buccal nerve plays an important role in oral health, as it provides sensation to the cheek and gums. Damage or injury to this nerve can lead to numbness, tingling, and pain on one side of the face. Proper dental care, including regular check-ups and cleanings, can help prevent damage to the buccal nerve and ensure optimal oral health.
