It is not unusual for teeth to hurt after a filling or crown. If the filling is deep or near the nerve or pulp, the filling may ache or be sensitive for several days or weeks. When the cavity is close to the nerve, the body will build a layer of dentin over time to insulate itself from the pain transmitted to the nerve form the filling. Here are some usual reasons fillings will hurt after a tooth is filled: 1) Normal response to the trauma, this pain should subside in several days or weeks. 2) If the tooth hurts only when you bite, the filling may be too high, especialy if this in the first or only tooth you hit when you bite.
