The face is a unique part of the body with its individual anatomical characteristics. While the dental clinician is usually focused on the oral cavity, the physical examination should involve close attention to the neurosensory status of the facial skin. Furthermore, skin sensitivity should be assessed pre- and postoperatively in conjunction with dental interventions. The face can be divided into several functional units, such as the eyes, nose, mouth/lips, and cheeks. With regard to the neurosensory supply of the skin, various innervation territories of the face can be distinguished representing the three divisions of the trigeminal nerve. In addition, cutaneous branches of the cervical plexus provide sensitivity to the lower and lateral portions of the face. The objective of the present article is to provide the dental clinician with a literature update of the neurosensory innervation of the face.
