What is the primary purpose of a buccal nerve block?

The primary purpose of a buccal nerve block is to anesthetize the soft tissues in the cheek. This technique specifically targets the buccal nerve, which is responsible for sensory innervation to the buccal mucosa in the lower jaw. By administering a buccal nerve block, a clinician can effectively numb the tissues adjacent to the molars, allowing for more comfortable procedures involving the buccal aspect of the mandibular molars.

While other options may concern anesthetic techniques, they do not accurately describe the specific aim of the buccal nerve block. The partial or whole anesthetics acting on teeth in the lower jaw would be achieved through different nerve blocks, such as the inferior alveolar nerve block, which targets the entire mandibular quadrant, including the teeth. Similarly, maxillary arch anesthetics require different approaches to successfully numb these structures. Therefore, it is clear that the buccal nerve block is distinctly focused on the soft tissue aspect of the cheek area.
