Nervous system
Looks like
The end branch of the inferior alveolar nerve, leaving the lower jaw through a hole below the premolars.
What it does
Brings feeling from the lower lip, chin and the front of the lower gum.
Keeping it well
A new numb chin without injury can be a sign of cancer spreading to the jaw — see a doctor.
