See a dentist: What you are describing is not a normal occurrence. You should be examined by a dentist without delay.

Needs an exam: Please see a local dentist to have the teeth examined. The pain is of concern.

Consult: I suggest a consult with a dentist as soon as possible. This requires a personal exam and x-rays to see what's going on and what your treatment options are. Sooner rather than later before it flares up and you have a true emergency.
