What does it mean when toothache pain spreads into my face?

See a dentist. If your pain is getting worse you need to see a dentist. Increasing pain means that whatever is causing your problem (usually infection) is getting worse and you need treatment. Teeth are connected with the same nerve as some of your face. Facial pain indicates the nerve is getting more irritated.
Nerve Involvement. Usually indicates 5th cranial nerve involvement which is pretty serious to be caused by a toothache. You need to see a dentist asap.
