You may want to have the endodontist (
root canal specialist) take a look at the
tooth and see if it needs a
root canal. Sometimes excess cement can cause tooth pain in the area as well. Sometimes if the cavity is deep, it can take some time before the teeth develop symptoms and its unpredictable when that'll happen. Another issue may be pulpal degeneration, in which the nerve will begin to die and develop problems due to its long history of fillings, cavities, crowns, etc.
