Can a tooth ache cause you chin to hurt?

It's possible: The chin is innervated by the mental nerves which are the final branches of the trigeminal nerve which innervates your lower teeth before exiting to your chin. It is possible for any pathology--toothaches, cysts, cancer--along the path of innervation to cause pain or numbness in the chin. See your dentist.

Chin pain : Absolutely. Depending on the type of pain (acute, chronic, dull, sharp, intermittent, etc.) dental examination and X-ray is needed to determine the cause. If dental fillings are present, chronic trauma caused by oral habits, occlusion (bite), gum disease can all contribute to pain. You will need to see a general dentist to determine whether the cause is of dental origin.
