the ophthalmic, maxillary, and mandibular. The pain of
trigeminal neuralgia occurs almost exclusively
in the maxillary and mandibular divisions.
You most commonly feel pain in the maxillary nerve, which runs along your cheekbone, most of your nose, upper lip, and upper teeth. Next most commonly affected is the mandibular nerve, affecting your lower cheek, lower lip, and jaw.
In almost all cases (97%), pain will be restricted to one side of your face.
