Which nerve block does NOT anesthetize the teeth?

The mental nerve block and the buccal nerve block do not provide anesthesia to the teeth.

The mental nerve block targets the mental nerve, which primarily anesthetizes the skin over the chin and lower lip, as well as the anterior teeth' labial mucosa, but does not affect the pulp of the teeth. This block is excellent for procedures involving soft tissue around the premolars and incisors, but it does not offer numbness to the actual teeth themselves.

The buccal nerve block targets the buccal nerve, which provides sensation to the buccal mucosa and the gingiva of molar teeth but also does not directly anesthetize any teeth. Its purpose is more to manage soft tissue anesthesia than to address dental pulpal anesthesia.

In contrast, both the mental and buccal nerve blocks can assist in providing comfort during dental procedures involving those regions without affecting the teeth themselves, which is why this combination is correctly identified as producing no dental anesthesia.
