Which nerve supplies sensation to the lingual gingivae of all lower teeth?

• A. ID Nerve
• B. Long Buccal Nerve
• C. Maxillary Nerve
• D. Mandibular Nerve

Answer: (A)

The nerve that supplies sensation to the lingual gingivae of all lower teeth is indeed the inferior alveolar (IA) nerve, which is a branch of the mandibular nerve. The IA nerve is responsible for sensory innervation to the lower teeth, including the pulps and surrounding structures. Specifically, it provides sensation to the lingual gingivae, making it essential for the feeling in that area. The importance of understanding the roles of these nerves lies in their involvement in dental procedures and patient care. The inferior alveolar nerve block, for instance, numbs this area during dental surgeries or fillings, preventing pain during treatment. In contrast, the long buccal nerve provides sensation to the buccal gingiva of the lower molars, while the maxillary nerve pertains to the upper teeth and structures, and the mandibular nerve serves as a main trunk from which several branches, including the inferior alveolar nerve, arise. Thus, it is crucial to recognize the specific anatomical designations of these nerves when considering dental treatments and their implications.
